Is it possible to set the position alignment for a GroupBox
Header
in WPF? The default is to place in the top left corner of the GroupBox
outline but I would like it to be centered at the top. I know that you can set the properties of the text using:
<GroupBox Grid.Row="1" HorizontalAlignment="Center">
<GroupBox.Header>
<TextBlock Text="Cash Match" Foreground="Black" FontWeight="Bold"/>
</GroupBox.Header>
</GroupBox>
But I'm looking to set the position of it with respect to the GroupBox
outline.
It's simple! Just edit Template of GroupBox:
In Blend, do the following :
Search for following section:
<Border x:Name="Header" Padding="3,1,3,0"
Grid.Column="1" Grid.Row="0" Grid.RowSpan="2">
...
</Border>
Change Grid.Column
to 2
HorizontalAlignment="Right"
You have just aligned the header to right!!! But bot the white gap behind it. For that,
Now search for following section :
<Border BorderBrush="White" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="4" Grid.ColumnSpan="4" Grid.Row="1" Grid.RowSpan="3">
<Border.OpacityMask>
...
</Border.OpacityMask>
...
</Border>
Add RenderTransformOrigin="0.5,0.5"
to the border
Just above , add following code (this will shift the "white gap" behind header to right:
<Border.RenderTransform>
<ScaleTransform ScaleX="-1"/>
</Border.RenderTransform>
You are done! You just got a GroupBox with right aligned header!!!
Please tell me if this is what you required.
Changing the group-box-header alinment will result in non-OS-conform controls.
Therefore, I think you won't be able to change this using the default styles. A custom template will solve your problem.
