Make WPF TextBox begin at a certain location in the box

I can't seem to find the answer online when I search around, I don't know if this is because there is an easier way that I don't know about.
I want my text box text to begin after the line on the picture below:
Is there something that I can set in the XAML or in he C# code.
Also, if there is a solution, the data that the user enters it getting stored in a database so I don't want there to be space before there data if you get me.
Any idea's please let me know, Thanks.
<Label Content="Firstname:" HorizontalAlignment="Left" Margin="84,177,0,0" VerticalAlignment="Top" Foreground="#FFACACAC" FontSize="13"/>
<TextBox x:Name="txtFirstname" HorizontalAlignment="Left" Height="43" Margin="59,166,0,0" TextWrapping="Wrap" VerticalAlignment="Top" Width="433" PreviewTextInput="TextOnlyValidation" VerticalContentAlignment="Center" FontSize="16" />
<GridSplitter HorizontalAlignment="Left" Height="34" Margin="190,171,0,0" VerticalAlignment="Top" Width="1" Background="#FFACACAC"/>

You need to create a new style for your TextBox, and change the layout inside it :

Hope this helps.

You mentioned a couple of problems.
(1) Want text to appear after that line
Solution is to set padding, so that there is a large dead-space on the left of the textbox. How much? However wide your label is, or whatever it takes to get to the line.
Use something like Padding="15,0,0,0" to just set the left padding.
(2) Adding padding won't let you click in TextBox
Click where? Over the label, or to the right of the line? You can set IsHitTestVisible="False" on the label to ensure it doesn't get in the way of your clicking.
But finally, this is not a great design. You've got absolute positions for Margin whereas you want to try and create a layout that flows and adapts to the space given. A Grid will help with this. You're also trying to overlay two UI elements, and then work around problems introduced by doing this. This is a clear sign you're doing things wrong! The best solution, if a control doesn't do what you want, is to create your own control derived from those that are closest to what you want. You would be better off creating your own TextBox-with-inbuilt-label component and using that.

You could make a grid with 2 columns around the label and textbox.
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="50" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Label Grid.Column="0" Content="Firstname:" HorizontalAlignment="Left" Margin="84,177,0,0" VerticalAlignment="Top" Foreground="#FFACACAC" FontSize="13"/>
<TextBox Grid.Column="1" x:Name="txtFirstname" HorizontalAlignment="Left" Height="43" Margin="59,166,0,0" TextWrapping="Wrap" VerticalAlignment="Top" Width="433" PreviewTextInput="TextOnlyValidation" VerticalContentAlignment="Center" FontSize="16" />
</Grid>

Just set the correct amount of padding:
<Grid VerticalAlignment="Center">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="Firstname" VerticalAlignment="Center" Margin="5" />
<TextBox Grid.Column="1" Padding="10,0,0,0" BorderThickness="0" VerticalAlignment="Center" />
</Grid>

To avoid spaces in your value you can use :
string firstname = txtFirstname.text.Trim()

Auto hover color for buttons based on their Background color

I've googled a lot but I've found nothing about this situation.
I have several flat Buttons with different Background colors, but the hover color is the same for all of them! I want each Button has its own hover color based on its background, for example gets a little lighter.
I've tried making custom styles and I reduced the Opacity in IsMouseOver trigger, but It's not what I want because it also affects the content of the button and not only the background color!
Win32 C# applications have a Flat Appearance property that do the trick automatically. When you choose a color for the BackColor and set the button as Flat, it takes care of all states color (Hover color, Disabled color, ...), however I've no idea how to do this in WPF.
Thank you in advance

the hover color is the same for all of them!
This is probably because in your Button's style, you have one single Background brush when IsMouseOver is True.
because it also affects the content of the button and not only the background color
This is probably because when the panel (likely a Border) you are animating is also the parent of the content control(e.g. ContentPresenter, ContentControl), so the Opaciy of this content control is also affected.
To solve these problems, you just need to create some visual elements (e.g. Rectangles, Borders) at the same level as your content control, and animate them based on which trigger is activated.
Here is a simple example.
<Window.Resources>
<Style x:Key="FocusVisual">
<Setter Property="Control.Template">
<Setter.Value>
<ControlTemplate>
<Rectangle Margin="2" SnapsToDevicePixels="true" Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" StrokeThickness="1" StrokeDashArray="1 2"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<SolidColorBrush x:Key="Button.Static.Background" Color="#FFDDDDDD"/>
<SolidColorBrush x:Key="Button.Static.Border" Color="#FF707070"/>
<SolidColorBrush x:Key="Button.MouseOver.Background" Color="#FFBEE6FD"/>
<SolidColorBrush x:Key="Button.MouseOver.Border" Color="#FF3C7FB1"/>
<SolidColorBrush x:Key="Button.Pressed.Background" Color="#FF737B7F"/>
<SolidColorBrush x:Key="Button.Pressed.Border" Color="#FF2C628B"/>
<SolidColorBrush x:Key="Button.Disabled.Background" Color="#FFF4F4F4"/>
<SolidColorBrush x:Key="Button.Disabled.Border" Color="#FFADB2B5"/>
<SolidColorBrush x:Key="Button.Disabled.Foreground" Color="#FF838383"/>
<Style x:Key="MyButtonStyle" TargetType="{x:Type Button}">
<Setter Property="FocusVisualStyle" Value="{StaticResource FocusVisual}"/>
<Setter Property="Background" Value="{StaticResource Button.Static.Background}"/>
<Setter Property="BorderBrush" Value="Transparent"/>
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
<Setter Property="HorizontalContentAlignment" Value="Center"/>
<Setter Property="VerticalContentAlignment" Value="Center"/>
<Setter Property="Padding" Value="4"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Grid SnapsToDevicePixels="true">
<Rectangle x:Name="BackgroundVisual" Fill="{TemplateBinding Background}"/>
<Rectangle x:Name="PressedVisual" Fill="{DynamicResource Button.Pressed.Background}" Opacity="0"/>
<Rectangle x:Name="DisabledVisual" Fill="{DynamicResource Button.Disabled.Background}" Opacity="0"/>
<ContentPresenter x:Name="contentPresenter" Focusable="False" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsDefaulted" Value="true"/>
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="Opacity" TargetName="BackgroundVisual" Value="0.6"/>
</Trigger>
<Trigger Property="IsPressed" Value="true">
<Setter Property="Opacity" TargetName="PressedVisual" Value="1"/>
</Trigger>
<Trigger Property="IsEnabled" Value="false">
<Setter Property="TextElement.Foreground" TargetName="contentPresenter" Value="{StaticResource Button.Disabled.Foreground}"/>
<Setter Property="Opacity" TargetName="DisabledVisual" Value="1"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
<Setter Property="BorderThickness" Value="0"/>
</Style>
</Window.Resources>
Here is how the style looks.
Hope this helps! :)

Check this out :
http://learnwpf.com/post/2006/03/06/How-do-I-change-an-items-appearance-on-mouseover-in-WPF.aspx
for Background you can simply set the "Background" property instead of setting the "BitmapEffect" property.
Hope this helps

ListBox/Rectangle Margins, Changing Look of Selected Item, Binding for Selected Item

A few questions regarding ListBox here (3 actually)
1. ListBoxItem/Rectangle Margins
From the image, I think the margins are uneven, the left seems like it have more margin. And this is when my margins is already set to
<ListBox.ItemTemplate>
<DataTemplate>
<Rectangle Width="20" Height="20" Margin="1,2,2,2">
<Rectangle.Fill>
<SolidColorBrush Color="{Binding}" />
</Rectangle.Fill>
</Rectangle>
</DataTemplate>
</ListBox.ItemTemplate>
2. How can I change the Selected Item Look?
I don't want that blue background, can I just have a border?
I tried the example from Change WPF DataTemplate for ListBox item if selected
with this code
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="ContentTemplate">
<Setter.Value>
<DataTemplate>
<Rectangle Width="20" Height="20" Margin="1,2,3,2">
<Rectangle.Fill>
<SolidColorBrush Color="{Binding}" />
</Rectangle.Fill>
</Rectangle>
</DataTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="ContentTemplate">
<Setter.Value>
<DataTemplate>
<Border BorderBrush="DarkGray" BorderThickness="1">
<Rectangle Width="20" Height="20" Margin="1,2,3,2">
<Rectangle.Fill>
<SolidColorBrush Color="{Binding}" />
</Rectangle.Fill>
</Rectangle>
</Border>
</DataTemplate>
</Setter.Value>
</Setter>
</Trigger>
</Style.Triggers>
</Style>
</ListBox.ItemContainerStyle>
and got something like
3. Binding for Selected Item
I am trying to bind the selected color to a property of the view model. If the color in the view model does not exists in the list of colors provided, no color should be selected. Think of this as an alternative way to select color, I have selection of colors via RGB/HSB sliders. I tried
<ListBox ItemsSource="{Binding ThemeColors}" SelectedValue="{Binding Color}" SelectionChanged="ListBox_SelectionChanged" ...
then in C#
private void ListBox_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
var listBox = (ListBox)sender;
if (listBox.SelectedValue != null)
Color = (Color)listBox.SelectedValue;
}
But after that, when I try to select colors with the sliders, I get some weird jerking and sometimes the color always snap back to the color selected from the list box. But sometimes it works fine, I am quite confused.

1.ListBoxItem comes with a default Padding of "2,0,0,0", that's why the Margin seems of. This can be changed in the ItemContainerStyle of the ListBox
<ListBox.ItemContainerStyle>
<Style TargetType="{x:Type ListBoxItem}">
<Setter Property="Padding" Value="0,0,0,0"/>
</Style>
</ListBox.ItemContainerStyle>
(Although I seem to get the best result with a Padding of 1,0,0,0. Can't explain that..)
2.To remove the Background and only display the Border I think you'll have to retemplate the ListBoxItem and modify the Triggers to use BorderBrush instead of Background for the Border.
<ListBox.ItemContainerStyle>
<Style TargetType="{x:Type ListBoxItem}">
<Setter Property="Padding" Value="0,0,0,0"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListBoxItem}">
<Border x:Name="Bd" SnapsToDevicePixels="true" Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="1" Padding="{TemplateBinding Padding}">
<ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="true">
<Setter Property="BorderBrush" TargetName="Bd" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/>
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.HighlightTextBrushKey}}"/>
</Trigger>
<MultiTrigger>
<MultiTrigger.Conditions>
<Condition Property="IsSelected" Value="true"/>
<Condition Property="Selector.IsSelectionActive" Value="false"/>
</MultiTrigger.Conditions>
<Setter Property="BorderBrush" TargetName="Bd" Value="{DynamicResource {x:Static SystemColors.ControlBrushKey}}"/>
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
</MultiTrigger>
<Trigger Property="IsEnabled" Value="false">
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.GrayTextBrushKey}}"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ListBox.ItemContainerStyle>
For 3. I'm not sure I understand what you want to do

Blinking button on WPF application

My WPF application has a style manager that I have built on blend.
My problem is this: I've got a login button that blinks occasionally and i can't figure out how to remove this behavior.
Here's the style code for my login box:
<Style x:Key="LoginBoxGrid" TargetType="{x:Type Grid}">
<Setter Property="Background">
<Setter.Value>
<ImageBrush ImageSource="/Client;component/Assets/images/LoginBox.png" Stretch="None" TileMode="Tile"/>
</Setter.Value>
</Setter>
<Setter Property="Opacity" Value="0.765"/>
<Setter Property="Width" Value="411"/>
<Setter Property="HorizontalAlignment" Value="Left"/>
<Setter Property="Margin" Value="126,150,0,111"/>
</Style>
<Style x:Key="LoginBoxHeader" TargetType="{x:Type Label}">
<Setter Property="Grid.Column" Value="2"/>
<Setter Property="Margin" Value="-16.183,18.347,0,0"/>
<Setter Property="Width" Value="64.994"/>
<Setter Property="FontSize" Value="16"/>
<Setter Property="FontWeight" Value="Bold"/>
<Setter Property="FontStyle" Value="Italic"/>
<Setter Property="Foreground" Value="White"/>
<Setter Property="VerticalAlignment" Value="Top"/>
<Setter Property="HorizontalAlignment" Value="Left"/>
<Setter Property="FontFamily" Value="/Client;component/Assets/Fonts/#Arial Black"/>
</Style>
<Style x:Key="LoginBtn" TargetType="{x:Type Button}">
<Setter Property="Grid.Column" Value="2"/>
<Setter Property="Margin" Value="16.6,9.022,9.282,8"/>
<Setter Property="Grid.Row" Value="4"/>
<Setter Property="Width" Value="164"/>
<Setter Property="BorderThickness" Value="0"/>
<Setter Property="Opacity" Value="0.78"/>
<Setter Property="IsDefault" Value="True"/>
<Setter Property="Foreground" Value="White"/>
<Setter Property="Background">
<Setter.Value>
<ImageBrush ImageSource="/Client;component/Assets/images/LoginBtn.png"/>
</Setter.Value>
</Setter>
</Style>
And here's my code for the window:
<Grid Style="{StaticResource LoginBoxGrid}" >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="0.127*"/>
<ColumnDefinition Width="0.326*"/>
<ColumnDefinition Width="0.462*"/>
<ColumnDefinition Width="0.085*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="0.269*"/>
<RowDefinition Height="0.028*"/>
<RowDefinition Height="0.256*"/>
<RowDefinition Height="0.223*"/>
<RowDefinition Height="0.178*"/>
<RowDefinition Height="0.046*"/>
</Grid.RowDefinitions>
<Label Content="User Name" Grid.Column="1" Margin="43.986,23.1,8,8" Grid.Row="2" Width="82" BorderThickness="0" FontFamily="Arial" FontWeight="Bold" FontStyle="Italic"/>
<Label Content="Password" Grid.Column="1" Margin="43.986,15.873,8,8" Grid.Row="3" Width="82" BorderThickness="0" FontFamily="Arial" FontWeight="Bold" FontStyle="Italic"/>
<PasswordBox Grid.Column="2" Name="PassTb" HorizontalAlignment="Left" Margin="8,18.877,0,8" Grid.Row="3" Width="172.6" d:LayoutOverrides="Height"/>
<TextBox Grid.Column="2" Name="UserTb" HorizontalAlignment="Left" Margin="9.282,23.1,0,11.004" Grid.Row="2" TextWrapping="Wrap" Text="TextBox" Width="172.6" d:LayoutOverrides="Height"/>
<Label Style="{StaticResource LoginBoxHeader}" Content="Login" />
<Button Name="LoginBtn" Style="{StaticResource LoginBtn}" Content="Login" />
</Grid>
The Button I'm talking about is called "LoginBtn", as is its style.
How can I remove that blinking behavior? Thanks in advance.

That flashing is due to the default style that WPF uses for buttons. To be more specific, it's due to the Trigger on the button's control template. To remove this, go into blend, right click on the button and select "Edit Template"->"Edit a copy". Click on the child element of the content presenter (by default, this is the control called "Chrome"). Then, in the triggers tab, inactive RenderDefaulted by pressing "- trigger". That trigger will keep the button from blinking. If you just want the XAML for all of that, here it is wrapped by windows.resource...
<Window.Resources>
<Style x:Key="ButtonFocusVisual">
<Setter Property="Control.Template">
<Setter.Value>
<ControlTemplate>
<Rectangle Margin="2" SnapsToDevicePixels="true" Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" StrokeThickness="1" StrokeDashArray="1 2"/>

<Setter Property="Foreground" Value="#ADADAD"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>

Then, wherever you button is, apply this style...
<Button Style="{DynamicResource BoringButtonStyle}"/>
Update: The default button style has changed over the years. The idea is the same, use Blend for Visual Studio to edit the templete of the element you want to change. For this button, simply remove the IsDefaulted trigger entirly. Here is an updated code snippet.
<Style x:Key="FocusVisual">

Simple solution: Set button's "Focusable" to False.

A slightly less obtrusive way of removing that blinking would be to set a new ControlTemplate for ButtonBase with the offending bindings removed.
I took this via StyleSnooper from the Button default Style and revamped/simplified it to be a Style for ButtonBase that simply provides a new ControlTemplate*. To do this, add an assembly reference to Presentation.Aero and introduce the Microsoft.Windows.Themes namespace in your ResourceDictionary.
Here, I specifically removed the affected Button's ability to "blink" on its IsDefault property by hardcoding RenderDefaulted to false; you'll probably also want to replace the RenderMouseOver TemplateBinding.
<ResourceDictionary [...]
xmlns:mwt="clr-namespace:Microsoft.Windows.Themes;assembly=PresentationFramework.Aero">
<Style TargetType="{x:Type ButtonBase}"
x:Key="NonBlinkingButtonBase">
<Setter Property="Control.Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ButtonBase}">
<mwt:ButtonChrome Background="{TemplateBinding Panel.Background}"
BorderBrush="{TemplateBinding Border.BorderBrush}"
RenderDefaulted="False"
RenderMouseOver="{TemplateBinding UIElement.IsMouseOver}"
RenderPressed="{TemplateBinding ButtonBase.IsPressed}"
Name="Chrome"
SnapsToDevicePixels="True">
<ContentPresenter RecognizesAccessKey="True"
Content="{TemplateBinding ContentControl.Content}"
ContentTemplate="{TemplateBinding ContentControl.ContentTemplate}"
ContentStringFormat="{TemplateBinding ContentControl.ContentStringFormat}"
Margin="{TemplateBinding Control.Padding}"
HorizontalAlignment="{TemplateBinding Control.HorizontalContentAlignment}"
VerticalAlignment="{TemplateBinding Control.VerticalContentAlignment}"
SnapsToDevicePixels="{TemplateBinding UIElement.SnapsToDevicePixels}" />
</mwt:ButtonChrome>
<ControlTemplate.Triggers>
<Trigger Property="UIElement.IsKeyboardFocused" Value="True">
<Setter Property="mwt:ButtonChrome.RenderDefaulted" TargetName="Chrome" Value="True" />
</Trigger>
<Trigger Property="ToggleButton.IsChecked" Value="True">
<Setter Property="mwt:ButtonChrome.RenderPressed" TargetName="Chrome" Value="True" />
</Trigger>
<Trigger Property="UIElement.IsEnabled" Value="False">
<Setter Property="TextElement.Foreground">
<Setter.Value>
<SolidColorBrush>
#FFADADAD</SolidColorBrush>
</Setter.Value>
</Setter>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Then use this style as a BasedOn for your Button:
<Style x:Key="LoginBtn"
TargetType="{x:Type Button}"
BasedOn="{StaticResource NonBlinkingButtonBase}">
[...your stuff...]
</Style>
(*) And yes, we should really have the ability to use BasedOn for ControlTemplates as well...

I've since my first answer ran into this problem when attaching images to buttons and I figured out by setting the image and button to stretch and using a size on the border it fixed the problem.
Example code..
<Border Width="45" Height="45">
<Button x:Name="buttonSend"
ToolTip="Send" Command="{Binding Path=SendCommand}" Style="{StaticResource actionButtonStyle}">
<Image Source="..\Images\Email-256.png" Stretch="Fill" />
</Button>

Having an issue with my TextBox control template

I am working on a simple textBox template, which is just two borders, one with a gradient background. Now, my specific issue is that I want to be able to set the foreground color of the textBox to whatever color I want and have it work correctly. However, I can't seem to get both the disabled foreground and enabled foreground colors to work together. If I set the foreground to red for example, when I disable the textBox, the foreground doesn't get changed to my disabled color. I tried binding the foreground in the IsEnabled="true" trigger but that doesn't seem to work. The foreground always stays red, no matter if the textBox is enabled or not.
Can you please take a look at the below template and tell me what I am doing wrong? Also, please point out to me any other mistakes I may have made since I am new at creating templates.
Thanks a lot.

There are a few different issues here all working against you. The first is that you're setting a specific Foreground value on your control instance, which has a higher priority than values set from Triggers in your Style for properties of the control itself. This is different than properties set on elements inside the ControlTemplate, like "Border". The way you're using Triggers to set the Border properties is illustrating that. Normally you would also want to use TemplateBindings to pull in values set on your control instance as defaults, like Background, which are currently being ignored.
To switch between two values of a property on your styled control, like you want to do with Foreground, you can use a Setter and a Trigger in your Style to provide a default and alternate value. This is still subject to being overridden by a value set on an instance. If you want to disallow instances overriding a Trigger set it up like the "Border" Trigger where you're setting values on elements inside the ControlTemplate.
The last change I'd recommend is switching to StaticResource for the Brushes you're pulling into your Style. In this case it probably won't make a difference, but in some cases a default Style can get pulled into a context that doesn't have any reference to the surrounding Resources from the file it was declared in. Using Static will guarantee that it will include those Resources no matter where it gets used. You may not run into this but it's a good habit to get into when setting up Styles/Templates like this.
Here's your code with those improvements:
<SolidColorBrush x:Key="DisabledForegroundBrush" Color="#888" />
<SolidColorBrush x:Key="DisabledBackgroundBrush" Color="#EEE" />
<Style x:Key="TextBoxControlTemplate1" TargetType="{x:Type TextBox}">
<Setter Property="KeyboardNavigation.TabNavigation" Value="None"/>
<Setter Property="AllowDrop" Value="true"/>
<Setter Property="Background">
<Setter.Value>
<LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
<GradientStop Color="#FF000000" Offset="0"/>
<GradientStop Color="#FF4D4D4D" Offset="1"/>
</LinearGradientBrush>
</Setter.Value>
</Setter>
<Setter Property="HorizontalContentAlignment" Value="Stretch"/>
<Setter Property="VerticalContentAlignment" Value="Stretch"/>
<Setter Property="FontFamily" Value="Segoe UI"/>
<Setter Property="FontSize" Value="12"/>
<Setter Property="Padding" Value="8,5,3,3"/>
<Setter Property="BorderThickness" Value="2"/>
<Setter Property="BorderBrush" Value="#FF000000"/>
<Setter Property="Foreground" Value="Red" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TextBox}">
<Grid>
<!--Take advantage of containment when possible to let the layout engine help you!-->
<Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="5" Padding="0" Background="#FF000000"/>
<Border x:Name="Border" BorderBrush="#FFFFFFFF" BorderThickness="1" CornerRadius="5" Padding="0" Margin="{TemplateBinding BorderThickness}"
Background="{TemplateBinding Background}"/>
<ScrollViewer Margin="0" x:Name="PART_ContentHost"/>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Background" Value="{StaticResource DisabledBackgroundBrush}" TargetName="Border"/>
<Setter Property="BorderBrush" Value="{StaticResource DisabledBackgroundBrush}" TargetName="Border"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Foreground" Value="{StaticResource DisabledForegroundBrush}"/>
</Trigger>
</Style.Triggers>
</Style>
And the TextBox using only the Style settings:
<TextBox Text="TEST" TextWrapping="Wrap" Canvas.Top="293.761" Canvas.Left="112" Style="{DynamicResource TextBoxControlTemplate1}"
Height="28.724" Width="232.25" IsTabStop="False" HorizontalContentAlignment="Right" VerticalContentAlignment="Center" />

A couple ideas to try:
Get rid of one of your triggers. Having two opposing triggers may not be a good idea. I would set the default Background, BorderBrush, and Foreground directly on your Border declaration, and remove the Enabled="True" trigger. Then, debugging is only a matter of getting the Enabled="False" trigger right.
Add the TargetName property to setter for your Enabled="False" trigger.
This is a longshot, but use UIElement.IsEnabled instead of just IsEnabled, like this: <Trigger Property="UIElement.IsEnabled">.
Hope something I've said here helps!

The possible reason is that your DisabledBackgroundBrush is not visible at the point where you use your style. Please try to add the styles into the ControlTemplate's resources:
<ControlTemplate TargetType="{x:Type TextBox}">
<ControlTemplate.Resources>
<SolidColorBrush x:Key="DisabledBackgroundBrush" Color="#EEE" />
...
</ControlTemplate.Resources>
...
By the way, your control template doesn't honour the values of your properties.
For example, you should perhaps use something like
<ScrollViewer Margin="{TemplateBinding Padding}" x:Name="PART_ContentHost"/>
in your control template.
