ContentPresenter triggers not working
contentpresenter, controltemplate, wpf
Solution
Got it!
I had the header like this:
<TabItem.Header>
<TextBlock>My Header</TextBlock>
</TabItem.Header>
Problem was, there's already a TextBlock inside the header, you don't need to wrap the text again.
<TabItem.Header>
My Header
</TabItem.Header>
And it works.
Problem
I have a ContentPresenter inside a ControlTemplate trying to layout a TabItem. I want the foreground color of the TextBlock inside the header to change color when the tab is selected. My template is the following: ``` <TabControl.Resources> <Style TargetType="TabPanel"> <Setter Property="HorizontalAlignment" Value="Right" /> </Style> <Style TargetType="TabControl"> <Setter Property="BorderThickness" Value="0,0,0,0"></Setter> </Style> <Style TargetType="TabItem"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type TabItem}"> <ContentPresenter x:Name="ContentSite" VerticalAlignment="Center" HorizontalAlignment="Center" ContentSource="Header" Margin="30,10,30,10"/> <ControlTemplate.Triggers> <Trigger Property="IsSelected" Value="True"> <Setter TargetName="ContentSite" Property="TextBlock.Foreground" Value="DarkGoldenrod"></Setter> </Trigger> <Trigger Property="IsSelected" Value="False"> <Setter TargetName="ContentSite" Property="TextBlock.Foreground" Value="Black"></Setter> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style> </TabControl.Resources> ``` Unfortunately the triggers are doing nothing. Several other posts here on SO show a `Setter` tag that looks exactly like mine, using `TargetName` to make sure we only change the header and not the whole tab. The property is recognized and compiles, but nothing happens. What the heck is going on, and what am I doing wrong? This has been driving me nuts for hours!
