I'm trying to add a context to an ellipse button but I do not know how I can accomplish it.
So far all what I can do is
<Ellipse Fill="{TemplateBinding Background}"/>
but I do not want a background, I want a text. If someone can help me in here that will help alot..
Here's the code:
<Button Grid.Column="0" Height="40" Width="40" Margin="-26,-10,26,10" FontWeight="Bold">
<Button.Template>
<ControlTemplate TargetType="{x:Type Button}">
<Ellipse/>
</ControlTemplate>
</Button.Template>
<Button.Content>
Meat
</Button.Content>
</Button>
If you can help to me, please copy and past the code with the answer:
<ControlTemplate TargetType="{x:Type Button}">
<Ellipse>
<ContentPresenter/>
</Ellipse>
</Grid>

<Grid >
<Path Style="{StaticResource Process}" ToolTip="Process">
<ControlTemplate> <Path Style="{StaticResource Process_DragThumb}"/> </ControlTemplate>

Currently I am working on wpf popup which contains a label, which constitute of textblocks inside the control template. Here my issue is that popup has a bottom border shadow. Already a border is there for the popup along with that this shadow effect increases the bottom border thickness, which looks like this (check the link below to see the screenshot for popup).
Wpf code is like this
Label Control template style
<Style x:Key="popuplabelstyle" TargetType="{x:Type Label}">
<Setter Property="OverridesDefaultStyle" Value="true" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Label}">
<Border BorderBrush="Red" x:Name="labelBorder" BorderThickness="1" Padding="12" Background="White" Height="auto" MinHeight="260" Width="220">
<StackPanel>
<TextBlock Text="ABCD" Margin="0,0,0,4" />
<TextBlock Text="abcd" Margin="0,4,0,0" />
</StackPanel>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
xaml code for popup
<Popup x:Name="Mypopup" Panel.ZIndex="2" Placement="MousePoint" HorizontalOffset="10" VerticalOffset="10" IsOpen="{Binding ">
<Label Style="{StaticResource popuplabelstyle}"/>
</Popup>
I don't know why it's happening like this. Can anyone help me to solve this?
See the screenshot of the popup in below link
Try to set the SnapsToDevicePixels and/or UseLayoutRounding property of the Border to True to enable pixel snap rendering:
<ControlTemplate TargetType="{x:Type Label}">
<Border BorderBrush="Red" x:Name="labelBorder"
BorderThickness="1" Padding="12" Background="White" Height="auto" MinHeight="260" Width="220"
SnapsToDevicePixels="True" UseLayoutRounding="True">
<StackPanel>
<TextBlock Text="ABCD" Margin="0,0,0,4" />
<TextBlock Text="abcd" Margin="0,4,0,0" />
</StackPanel>
</Border>
</ControlTemplate>
This should make the Border look sharper.
When should I use SnapsToDevicePixels in WPF 4.0?
I was under the impression that a ContentPresenter would display the content of a Control.
However, if I use this :
<Button Content="Remove table">
<Button.Template>
<ControlTemplate>
<Grid x:Name="grid" >
<Border x:Name="border" BorderBrush="Black" BorderThickness="1" >
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Border>
</Grid>
</ControlTemplate>
</Button.Template>
</Button>
No text actually gets displayed.
Where am I mistaken ?
Adding the TargetType="Button" will show the text you are expecting.
<ControlTemplate TargetType="Button">

I've created a custom progress bar as follows:
<!-- Custom progress bar -->
<Style
x:Key="CopyProgressBar"
TargetType="ProgressBar">
<Setter
Property="Template">
<Setter.Value>
<ControlTemplate
TargetType="ProgressBar">
<Grid>
<Border
x:Name="PART_Track"
CornerRadius="5"
BorderBrush="#BBC6C4"
BorderThickness="2" />
<Rectangle
x:Name="PART_Indicator"
Fill="#A5B2B0"
RadiusX="5"
RadiusY="5"
Margin="3"
HorizontalAlignment="Left" />
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Here's how it is used:
<ProgressBar
x:Name="copyProgress"
Height="13"
Width="279"
Canvas.Left="158"
Canvas.Top="103"
Minimum="0"
Maximum="100"
Style="{StaticResource CopyProgressBar}" />
It works quite well, but when the progress is full, the right side of the fill bar is clipped, which removes the rounding styling I'm going for. I've fiddled with padding, margins, max width, etc, but I can't find a way to prevent the clipping.
Here is an image:
This was an interesting one to answer. I finally got it nailed down to being the margin that was causing the problem. The progress bar sets the width of PART_Indicator based on the width of PART_Track regardless of the margin or paddings that are set. The following style will get you the desired behaviour.
<Style x:Key="CopyProgressBar" TargetType="ProgressBar">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ProgressBar">
<Border BorderBrush="#BBC6C4" BorderThickness="1" CornerRadius="5" Padding="1">
<Grid x:Name="PART_Track" >
<Rectangle x:Name="PART_Indicator" HorizontalAlignment="Left" Fill="#A5B2B0" RadiusX="5" RadiusY="5"/>
</Grid>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Wpf dropshadow disappears.
Here is how to reproduce.
Type the following in xaml pad.
<Page.Resources>
<DropShadowEffect x:Key="shadow"
Opacity="1"
ShadowDepth="1"
Color="Blue"
BlurRadius="30"/>
</Page.Resources>
<Grid>
<Button HorizontalAlignment="Left" VerticalAlignment="Top" Margin="0,0,0,0">
<Button.Style>
<Style TargetType="{x:Type Button}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border x:Name="Bd"
BorderBrush="Black" BorderThickness="1"
Background="Yellow"
CornerRadius="8"
Effect="{StaticResource shadow}">
<TextBlock Text="Hello out there" HorizontalAlignment="Center" VerticalAlignment="Center" />
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Button.Style>
</Button>
</Grid>
You should see some text with a border abound it, and a drop shadow around the border.
Now change the Margin="0,0,0,0" to Margin="0,300,0,0", and size your xaml pad window so you can see the border. On my machine, the drop shadow is now gone.
Anyone else see this? Please help.
I wish I had a good explanation for you, but there were some weird things in your XAML that I played with and I think I have a solution for you.
If you use a Grid, most likely you want to lay out a specific number of rows and columns. You should specify those. This doesn't affect your problem, however.
Likewise, you should specify the Row and Column for your element because you'll eventually need to put this information in your XAML anyway. It's a good habit to start with IMO.
The problem that I can't explain is with the combination of HorizontalAlignment and VerticalAlignment. When you put the Button in the Grid, I would expect the Button to take up the entire space, but it doesn't. The only way you can make this work as far as I could figure out was to specify Height and Width. If you do this, the Effect will work. I found that the threshold in your original XML was a total Y margin of 239. For example, if you used 0,239,0,0, it would fail. If you used 0,139,0,100, it would also fail because the sum is 239. Weird stuff.
Here's my XAML that works:
<Page.Resources>
<DropShadowEffect x:Key="shadow"
Opacity="1"
ShadowDepth="2"
Color="Blue"
BlurRadius="30"/>
</Page.Resources>
<Grid Width="Auto" Height="Auto">
<Grid.RowDefinitions>
<RowDefinition></RowDefinition>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition></ColumnDefinition>
</Grid.ColumnDefinitions>
<Button Width="90" Height="30" HorizontalAlignment="Left" VerticalAlignment="Top" Margin="0,300,0,0" Grid.Row="0" Grid.Column="0">
<Button.Style>
<Style TargetType="{x:Type Button}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border x:Name="Bd"
BorderBrush="Black" BorderThickness="1"
Background="Yellow"
CornerRadius="8"
Effect="{StaticResource shadow}">
<TextBlock Text="Hello out there" HorizontalAlignment="Center" VerticalAlignment="Center" />
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Button.Style>
</Button>
EDIT The OP does not want to specify a size for the Button because the Content of the Button can change dynamically. It turns out that if you set the MinHeight to something like 18 (I think this is reasonable for most content), the dropshadow effect will work again.
<Border x:Name="Bd" BorderBrush="Black" BorderThickness="1" Background="Yellow" CornerRadius="8" Effect="{StaticResource shadow}" MinHeight="18">
<StackPanel Orientation="Vertical">
<TextBlock>hi</TextBlock>
<TextBlock>there</TextBlock>
</StackPanel>
</Border>
