I am trying to add content to a groupbox header, so that part of the content aligns to the left and the other part aligns to the right.
I've tried adding a grid as the content to the header with 2 columns, but everything aligns left. I want column 1 to align left, and column 2 to align on the right side of the group box.
Is this even possible?
Thanks
The problem here is, which size the tab-header should use. You can define your header as described and set minumum width for your Grid. This would probably have the effect you're looking for.
<Grid MinWidth="250">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<TextBlock Text="Test on the left"/>
<TextBlock Grid.Column="1" Text="Right" HorizontalAligment="Right" />
</Grid>
More influence for the optical style of GroupBox you can get through the HeaderTemplate and the Template-property.
