How do I change transparancy/opacity on just the header

[Kjell]

I have been asked to make the header of a RadWindow transparant but this should not affect the content, how can I do this?

I am using VS2010/SL4/.Net4, Windows server 2003, 7014 build of telerik controls for SL.

Hello Kjell,

You can use a DataTemplate as a RadWindow.HeaderTemplate and set a background in that DataTemplate. Please check this article on RadWindow Header.

Let me know if you need further guidance, I will be glad to help.

Which article?

I'm getting closer, tried this:

 

 

 

<telerik:RadWindow.HeaderTemplate>

 

 

 

 

<DataTemplate>

 

 

 

 

<Border Background="Green">

 

 

 

 

<TextBlock Text="Select Email Folders" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"/>

 

 

 

 

</Border>

 

 

 

 

</DataTemplate>

 

 

 

 

</telerik:RadWindow.HeaderTemplate>

 

I am using green just so I can see it easier in the designer, but it only covers there the text is, not the entire header width or the window border.

Ok got another step closer by setting borderbrush and borderbackground, still need to figure out how to get my background across the entire header.

I tried going another route and editing the template in Blend (which I was trying to avoid), but even there the transparancy settings only seem to work if I set the opacity for the entire control.

Ok this might be a hack but for now I'm just hardcoding the theme to "Transparant", this does what I need.
