Rounded edge 3D style button in WPF

I am trying to create a round edge 3D shape styled button in WPF. I want to create a button look like this image.
<Style TargetType="{x:Type Button}" >
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Grid>
<Rectangle x:Name="GelBackground" Opacity="1" RadiusX="9" RadiusY="9"

I used above code for creating button but it will not giving expected result. look like this.
Any help will be appreciated.

You can use borders inside a button template with a blur-effect to achive the requested result:
<Button Content="English" Width="100" Height="50">
<Button.Style>
<Style TargetType="{x:Type Button}" >
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ButtonBase}">
<Border CornerRadius="5" Background="{TemplateBinding Background}" Name="button" Width="100">
<Grid>
<Border BorderThickness="1,0,1,1" BorderBrush="Black" CornerRadius="{Binding ElementName=button, Path=CornerRadius}">
<Border.Effect>
<BlurEffect Radius="2" KernelType="Gaussian"/>
</Border.Effect>
</Border>
<Border BorderThickness="0,1,0,0" BorderBrush="White" Margin="2" Opacity="0.7" CornerRadius="{Binding ElementName=button, Path=CornerRadius}">
<Border.Effect>
<BlurEffect Radius="2" KernelType="Gaussian"/>
</Border.Effect>
</Border>
<ContentPresenter TextBlock.FontSize="{TemplateBinding FontSize}" TextBlock.FontFamily="{TemplateBinding FontFamily}" TextBlock.Foreground="{TemplateBinding Foreground}" VerticalAlignment="Center" HorizontalAlignment="Center" Content="{TemplateBinding Content}"></ContentPresenter>
</Grid>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Setter Property="Background" Value="#002060" />
<Setter Property="Foreground" Value="White" />
<Setter Property="FontSize" Value="20" />
<Setter Property="FontFamily" Value="Consolas" />
</Style>
</Button.Style>
</Button>
Result:

WPF XAML custom control to look like an LED

I wanted a control that looks like an LED and I found this code here
WPF Custom LED Checkbox
The problem is I can't get it to change colors. When I start typing the trigger OnColor or OffColor it says the member is not recognized. Here's the Code

Here's how I'm trying to use it
<local:LedControl IsChecked="true" IsEnabled="true" OnColor="Green" x:Name="Led1" Content="Led1" HorizontalAlignment="Left" Margin="10,33,0,0" VerticalAlignment="Top"/>
Here's the C# code in the User Control
using System.Windows;
using System.Windows.Controls;
using System.Windows.Media;
namespace WpfLed
{
public partial class LedControl : UserControl
{
static LedControl()
{
DefaultStyleKeyProperty.OverrideMetadata(typeof(LedControl), new FrameworkPropertyMetadata(typeof(LedControl)));
}
public static readonly DependencyProperty OnColorProperty =
DependencyProperty.Register("OnColor", typeof(Brush), typeof(LedControl), new PropertyMetadata(Brushes.Green));
public Brush OnColor
{
get { return (Brush)GetValue(OnColorProperty); }
set { SetValue(OnColorProperty, value); }
}
public static readonly DependencyProperty OffColorProperty =
DependencyProperty.Register("OffColor", typeof(Brush), typeof(LedControl), new PropertyMetadata(Brushes.Red));
public Brush OffColor
{
get { return (Brush)GetValue(OffColorProperty); }
set { SetValue(OffColorProperty, value); }
}
}
}
I've even tried rebuilding the solution, I'm sure its something simple that I'm overlooking.
EDIT:
I put the template under User control I forgot to post the C# code to add the dependencies but it still doesn't recognize that control. I updated the code above to reflect the changes. I'm new to using WPF and XAML, I don't get any errors in the UserControl just when I try to use it in the MainWindow.xaml

The class CheckBox(the type, that is) doesn't have a Dependency Property named OnColor and OffColor.
You need to create a new class, inheriting from CheckBox, and add to it those 2 new Dep Props.
Or use AttachedProperty instead.

Listview fore color will be unchanged in selection mode

I have the below XAML
however I want when the user box clicked on any of the textblock in he list view I want the forecolor of the text to be unchanged (currently changed to white)
instead I want the border color to be changed
how can I do that?
ListView x:Name="LV" ItemsSource= "{Binding Lggv}" SelectionChanged="dataGridData_SelectionChanged" >
<ListView.ItemTemplate>
<DataTemplate>
<StackPanel >
<Border BorderThickness="1" BorderBrush="Black">
<TextBlock Text="{Binding Info }" AllowDrop="True" >
<TextBlock.Background>
<LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
<GradientStop Color="#FFCEE6C6" Offset="0.008"/>
<GradientStop Color="#FF9ECF8C" Offset="0.987"/>
</LinearGradientBrush>
</TextBlock.Background>
</TextBlock>
</Border>
<Grid >
<Grid.Background>
<LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
<GradientStop Color="#FFC5DDFF" Offset="0"/>
<GradientStop Color="#FFA8C8F7" Offset="1"/>
</LinearGradientBrush>
</Grid.Background>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="1*"></ColumnDefinition>
<ColumnDefinition Width="1*"></ColumnDefinition>
<ColumnDefinition Width="1*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Border Grid.Column="0" BorderThickness="1" BorderBrush="Black">
<TextBlock Text="{Binding DateTime}" ></TextBlock>
</Border>
<Border Grid.Column="1" BorderThickness="1" BorderBrush="Black">
<TextBlock Text="{Binding ComPort}"></TextBlock>
</Border>
<Border Grid.Column="2" BorderThickness="1" BorderBrush="Black">
<TextBlock Text="{Binding Data}" ></TextBlock>
</Border>
</Grid>
</StackPanel>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>

You should distinguish between the item content and the item container. Handling item selection style should be the responsibility of the container. The following style defines a replacement for the visual representation of a ListViewItem with some basic properties. Depending on your desired visual, you may want to define a different style.
Define the style as resource:
<Style x:Key="ListViewItemStyle" TargetType="ListViewItem">
<Setter Property="Margin" Value="3"/>
<Setter Property="Background" Value="Transparent"/>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="BorderBrush" Value="Transparent"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ListViewItem">
<Border
Background="{TemplateBinding Background}"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}"
Padding="{TemplateBinding Padding}">
<ContentPresenter/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="BorderBrush" Value="Red"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="LightBlue"/>
</Trigger>
</Style.Triggers>
</Style>
The item will be displayed differently when the mouse is over (background color) and when the item is selected (red border). The foreground should stay untouched with this.
Usage:
<ListView ItemContainerStyle="{StaticResource ListViewItemStyle}">
<!-- your other code -->
</ListView>

SnapsToDevicePixels option

I am trying to style some tabs but I ran into this issue where the color of the border changes as I resize window. First of all, I used this http://blogs.intuidev.com/post/2010/01/25/TabControlStyling_PartOne.aspx to style the tabs if you're wondering about the code.
Also, here is the pic of what's wrong.
EDIT:
<Color x:Key="BorderColor_Base">#888</Color>
<Color x:Key="TabControl_BackgroundColor_Base">#CCC</Color>
<SolidColorBrush x:Key="TabControl_BackgroundBrush_Base"
Color="{StaticResource TabControl_BackgroundColor_Base}"/>
<LinearGradientBrush x:Key="TabItemPanel_BackgroundBrush"
StartPoint="0,0" EndPoint="0,1">
<LinearGradientBrush.GradientStops>
<GradientStop Offset="0.98" Color="Transparent"/>
<GradientStop Offset="0.99"
Color="{StaticResource BorderColor_Base}"/>
</LinearGradientBrush.GradientStops>
</LinearGradientBrush>
<SolidColorBrush x:Key="TabItem_BorderBrush_Selected"
Color="{StaticResource BorderColor_Base}" />
<Style TargetType="{x:Type TabControl}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="TabControl">

</Grid.RowDefinitions>
<Border Background="{StaticResource TabItemPanel_BackgroundBrush}"

<TabPanel Grid.Row="0" IsItemsHost="True"/>
</Border>

BorderThickness="2,1,1,1">
<!-- This is where the Content of the TabItem will be rendered. -->
<Viewbox>
<TextBlock x:Name="Header">
<ContentPresenter x:Name="ContentSite"

Margin="7,2,12,2"

</TextBlock>
</Viewbox>
</Border>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="False">
<Setter TargetName="Border" Property="Margin" Value="{StaticResource TabItemMargin_Base}" />
<Setter Property="Panel.ZIndex" Value="90" />
</Trigger>
<Trigger Property="IsSelected" Value="True">
<Setter Property="Panel.ZIndex" Value="100" />
<Setter TargetName="Border" Property="BorderThickness" Value="2,1,1,0" />
<Setter TargetName="Border" Property="Background" Value="White" />
</Trigger>
<Trigger Property="IsEnabled" Value="False">
<Setter TargetName="Header" Property="Background" Value="#CCC" />
<Setter TargetName="Header" Property="Foreground" Value="#888" />
<Setter Property="Panel.ZIndex" Value="80" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

The issue is with this brush:
<LinearGradientBrush x:Key="TabItemPanel_BackgroundBrush" StartPoint="0,0" EndPoint="0,1">
<LinearGradientBrush.GradientStops>
<GradientStop Offset="0.98" Color="Transparent" />
<GradientStop Offset="0.99" Color="{StaticResource BorderColor_Base}" />
</LinearGradientBrush.GradientStops>
</LinearGradientBrush>
You are using a gradient from transparent to #888 as your background, so you are seeing one of the colors "in between" transparent and #888. Instead, you can use a Transparent background and border of #888, like so:
<Style TargetType="{x:Type TabControl}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="TabControl">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="1*" />
<RowDefinition Height="10*" />
</Grid.RowDefinitions>
<Border Grid.Row="0" Background="Transparent" BorderBrush="#888" BorderThickness="0,0,0,1" Padding="{StaticResource TabItemPanel_Padding}"
SnapsToDevicePixels="True" />
<TabPanel Grid.Row="0" IsItemsHost="True" />
<ContentPresenter Grid.Row="1" ContentSource="SelectedContent" />
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
You may need to tweak the Margin of the Border and/or the TabPanel to ensure they line up correctly though.

Labas!
Try to increase line's height, for instance set it to 5 or 10 pixels. If color is wrong again it means that you wrong styled TabControl.

How to select default button in wpf dialog?

I am creating a WPF dialog. It is like our normal messagebox with ok and cancel button. How to create such a dialog so that the Ok button is selected when the dialog is opened?

To set a Window's Default button
Set your default button's IsDefault property to true.
Note that you can also set a Window's Cancel button by setting a button's IsCancel property to true.
To set the Selected (focused) button in a Window
If you want to select a particular button then use the Focus method like this:
yourButton.Focus();
You might do this when a Window loads (in the Window_Loaded event).
To select a particular button when your Window opens make sure its IsTabStop property is set to true and ensure its TabIndex property is lower than any other control on the Window.

just create a new button template and change the look and feel for the IsDefault=Tue state.
I just created a style and modified the state.
