How do I override theme for specific controls?

[Joshua]

In my code behind I have set to use an application wide theme e.g.
StyleManager.ApplicationTheme = new SummerTheme();

In my xaml I would like to style the gridviewgrouppanelcell e.g.

<Grid.Resources>
     <Style TargetType="telerik:GridViewGroupPanelCell">
         <Setter Property="Background" Value="Red"/>
     </Style>
 </Grid.Resources>

However, the background stays as the summer theme. How can I override it but keep the theme for other controls?

Hi Joshua,

Thank you for the feedback.
We can confirm the issue and it is known for us. We will increase its priority and will do our best to address it in one of the next builds.
In the meantime, could you send us your application with exact requirements what you are trying to achieve so we can provide you with appropriate workaround?
 
All the best,
Yordanka

My application is too big to send over but essentially the requirements are mentioned in the first post. I need to style the background of the gridviewgrouppanelcell while keeping the Summer theme on all other telerik controls.


Is there anyway that I can reference the GridViewGroupPanelCell in codebehind so I can change the background from there?

Hi Joshua,

 

Thank you for getting back to us! For the time being you cannot modify this element either in xaml or in code- behind in any theme different than the default one. On the other hand you may modify a built-in theme as described in the following online help article. As my colleague Yordanka proposed we will do our best to fix it in one of the next internal builds. 


Please excuse us for any inconvenience caused!

Kind regards,
