Make WPF TextBox begin at a certain location in the box - c#

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()
Info : Trim

Increase checkbox dimension in listview c# [duplicate]

I'm using a checkbox control like this:
<CheckBox VerticalAlignment="Bottom" IsChecked="{Binding Selected}"
Grid.Column="0"
FontSize="{StaticResource PhoneFontSizeLarge}"
Content="{Binding Name}">
</CheckBox>
The thing is that I change size to be a little bigger. In this case text is getting bigger, but tick itself remains the same. It looks ugly, can I resize checkbox somehow?
UPDATE
I'm doing it on windows phone so LayoutTransform not appropriate here

Try some thing like this:-
<CheckBox>
<CheckBox.LayoutTransform>
<ScaleTransform ScaleX="2" ScaleY="2" />
</CheckBox.LayoutTransform>
</CheckBox>
You can also check this link

<StackPanel Height="80"
Name="StackPanel1"
Orientation="Horizontal">
<Viewbox Height="{Binding Path=ActualHeight, ElementName=StackPanel1}">
<CheckBox />
</Viewbox>
</StackPanel>
Adjust the StackPanel height as needed.

Ended up with the following:
Add an empty checkbox
Open control in expression blend
Select checkbox there
Open Edit Template -> Edit Copy
It will create a new style with custom template that you will be able to assign to checkboxes.
It produced about 150 loc style, but I couldn't find another way

ScaleTransform scale = new ScaleTransform(2.0, 2.0);
yourCheckBox.RenderTransformOrigin = new Point(0.5, 0.5);
yourCheckBox.RenderTransform = scale;

Just add below mention codes in windows/usercontrol resource, it will automatically increase the default size of the []checkbox inside a Xaml control.

The closest I've come to getting to an answer is this post (code is omitted from my Style as it didn't have any effect) :-
Change ListViewItem background colour on mouse over
However, I'm still unable to control the mouseover and selected colours. I'm getting closer as the post above suggests that it is a button which is actually doing the highlighting and selecting but I don't know how to incorporate that in to my existing style.
Here's the current effect of the Style. The top row is selected, the third row is mouse-overed, the other two rows are normal.
Mouseover / selected colours
BTW, the Style I'm using was extracted from Blend and I tweaked it to use my app colours.
I don't think my Class code would be relevant here but correct me if I'm wrong and I will post it.

I think you need to add a style for the ListViewItems and set the ListView.ItemContainerStyle:
<!-- New style -->
<Style x:Key="StyleListViewItem" TargetType="ListViewItem">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="Green"/>
</Trigger>
<Trigger Property="IsSelected" Value="True">
<Setter Property="Background" Value="Blue"/>
</Trigger>
</Style.Triggers>
</Style>
<!-- Existing style -->
<Style x:Key="StyleListView" TargetType="ListView">
<Setter Property="ItemContainerStyle" Value="{StaticResource StyleListViewItem}"/>
<Setter Property="SnapsToDevicePixels" Value="true"/>
<!-- ... -->
</Style>

WPF: Cant find correct BorderBrush after setting Style

I have a button which I apply a style too. After the style is applied I have a test that checks the BorderBrush of the button to make sure the style was correctly applied. This test always fails, because the BorderBrush never gets updated in the Buttons properties.
Is there a way for me to get the actual BorderBrush being displayed? All i can get is the default BorderBrush, not the applied styles value.
The style I am using is this:
<Style x:Key="ActiveModuleBtnStyleOn" TargetType="Button">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Grid>
<Border Margin="0"
BorderThickness="3"
BorderBrush="Green"
Background="White"
VerticalAlignment="Stretch"
CornerRadius="4"
HorizontalAlignment="Stretch">
<Border.Effect>
<DropShadowEffect BlurRadius="10" Color="Black" Direction="325" Opacity=".5" RenderingBias="Quality" ShadowDepth="5" />
</Border.Effect>
</Border>
<TextBlock Margin="2" Text="{TemplateBinding Content}" TextWrapping="Wrap" TextAlignment="Center" VerticalAlignment="Center" HorizontalAlignment="Center"/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
<Setter Property="IsEnabled" Value="true"/>
</Style>
Then I apply the style like this:
if(var1 == 1)
TopologyNvTxBtn.Style = this.FindResource("ActiveModuleBtnStyleOn") as Style;
else
TopologyNvTxBtn.Style = this.FindResource("ActiveModuleBtnStyleOff") as Style;
In my test app, I want to check which style has been applied. The difference between the two styles is the border brush. I would like to do something like this:
if(TopologyNvTxBtn.BorderBrush == Brushes.Green)
return PASS;
But the BorderBrush never changes (e.g. in a watch window, it stays the same as the default buttons style BorderBrush), but its definitely applied correctly as in the GUI it turns green.
How can i access this property in my test?
Many thanks in advance

The BorderBrush property of the Button is not bound to anything in your template. You need to do this in the control template:
<Style x:Key="ActiveModuleBtnStyleOn" TargetType="Button">
<Setter Property="BorderBrush" Value="Green" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Grid>
<Border Margin="0"
BorderThickness="3"
BorderBrush="{TemplateBinding BorderBrush}"
Background="White"
VerticalAlignment="Stretch"
CornerRadius="4"
HorizontalAlignment="Stretch">
<Border.Effect>
<DropShadowEffect BlurRadius="10" Color="Black" Direction="325" Opacity=".5" RenderingBias="Quality" ShadowDepth="5" />
</Border.Effect>
</Border>
<TextBlock Margin="2" Text="{TemplateBinding Content}" TextWrapping="Wrap" TextAlignment="Center" VerticalAlignment="Center" HorizontalAlignment="Center"/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
<Setter Property="IsEnabled" Value="true"/>
</Style>
Notice how the BorderBrush is now bound to the BorderBrush property of the Button. Then you you can set the BorderBrush in the style and should be able to access it in this way:
if(TopologyNvTxBtn.BorderBrush == Brushes.Green)
Let me know if that works.
Cheers,
Eric

As I stated above, the Border is part of the Button ControlTemplate. I just launched Blend and got a copy of the "Factory" template. With this, you can do pretty much everything with it (assuming you know about Stylying.):
<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"/>

<Setter Property="BorderThickness" Value="1"/>
<Setter Property="HorizontalContentAlignment" Value="Center"/>
<Setter Property="VerticalContentAlignment" Value="Center"/>
<Setter Property="Padding" Value="1"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">

<ContentPresenter x:Name="contentPresenter" Focusable="False" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsDefaulted" Value="true">
<Setter Property="BorderBrush" TargetName="border" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="Background" TargetName="border" Value="{StaticResource Button.MouseOver.Background}"/>
<Setter Property="BorderBrush" TargetName="border" Value="{StaticResource Button.MouseOver.Border}"/>
</Trigger>
<Trigger Property="IsPressed" Value="true">
<Setter Property="Background" TargetName="border" Value="{StaticResource Button.Pressed.Background}"/>
<Setter Property="BorderBrush" TargetName="border" Value="{StaticResource Button.Pressed.Border}"/>
</Trigger>
<Trigger Property="IsEnabled" Value="false">
<Setter Property="Background" TargetName="border" Value="{StaticResource Button.Disabled.Background}"/>
<Setter Property="BorderBrush" TargetName="border" Value="{StaticResource Button.Disabled.Border}"/>
<Setter Property="TextElement.Foreground" TargetName="contentPresenter" Value="{StaticResource Button.Disabled.Foreground}"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
MSDN has a good introductory tutorial about Style and Templates. Besides, you can find tons of articles around the web!
The Button itself is pretty much this:
<Border
x:Name="border"
Background="{TemplateBinding Background}"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}"
SnapsToDevicePixels="true">
<ContentPresenter
x:Name="contentPresenter"
HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
Margin="{TemplateBinding Padding}"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}"
Focusable="False"
RecognizesAccessKey="True"
SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
</Border>
So, what your looking for is Triggers, you'll have to add and change as you wish these tags:
<ControlTemplate.Triggers>
<Trigger Property="IsDefaulted" Value="true">
<Setter Property="BorderBrush" TargetName="border" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="Background" TargetName="border" Value="{StaticResource Button.MouseOver.Background}"/>
<Setter Property="BorderBrush" TargetName="border" Value="{StaticResource Button.MouseOver.Border}"/>
</Trigger>
<Trigger Property="IsPressed" Value="true">
<Setter Property="Background" TargetName="border" Value="{StaticResource Button.Pressed.Background}"/>
<Setter Property="BorderBrush" TargetName="border" Value="{StaticResource Button.Pressed.Border}"/>
</Trigger>
<Trigger Property="IsEnabled" Value="false">
<Setter Property="Background" TargetName="border" Value="{StaticResource Button.Disabled.Background}"/>
<Setter Property="BorderBrush" TargetName="border" Value="{StaticResource Button.Disabled.Border}"/>
<Setter Property="TextElement.Foreground" TargetName="contentPresenter" Value="{StaticResource Button.Disabled.Foreground}"/>
</Trigger>
</ControlTemplate.Triggers>
Things to pay attention: TargetName and every <Trigger Property="IsDefaulted" Value="true"> alike!
Good luck!

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"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<LinearGradientBrush x:Key="ButtonNormalBackground" EndPoint="0,1" StartPoint="0,0">
<GradientStop Color="#F3F3F3" Offset="0"/>
<GradientStop Color="#EBEBEB" Offset="0.5"/>
<GradientStop Color="#DDDDDD" Offset="0.5"/>
<GradientStop Color="#CDCDCD" Offset="1"/>
</LinearGradientBrush>
<SolidColorBrush x:Key="ButtonNormalBorder" Color="#FF707070"/>
<Style x:Key="BoringButtonStyle" TargetType="{x:Type Button}">
<Setter Property="FocusVisualStyle" Value="{StaticResource ButtonFocusVisual}"/>
<Setter Property="Background" Value="{StaticResource ButtonNormalBackground}"/>
<Setter Property="BorderBrush" Value="{StaticResource ButtonNormalBorder}"/>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
<Setter Property="HorizontalContentAlignment" Value="Center"/>
<Setter Property="VerticalContentAlignment" Value="Center"/>
<Setter Property="Padding" Value="1"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Microsoft_Windows_Themes:ButtonChrome x:Name="Chrome" BorderBrush="{TemplateBinding BorderBrush}" Background="{TemplateBinding Background}" RenderMouseOver="{TemplateBinding IsMouseOver}" RenderPressed="{TemplateBinding IsPressed}" RenderDefaulted="{TemplateBinding IsDefaulted}" SnapsToDevicePixels="true">
<ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
</Microsoft_Windows_Themes:ButtonChrome>
<ControlTemplate.Triggers>
<Trigger Property="ToggleButton.IsChecked" Value="true">
<Setter Property="RenderPressed" TargetName="Chrome" Value="true"/>
</Trigger>
<Trigger Property="IsEnabled" Value="false">
<Setter Property="Foreground" Value="#ADADAD"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Window.Resources>
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">
<Setter Property="Control.Template">
<Setter.Value>

<Rectangle Margin="2" SnapsToDevicePixels="true" Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" StrokeThickness="1" StrokeDashArray="1 2"/>

</Trigger>

</Setter.Value>
</Setter>
</Style>

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>
