Gridview grouping style

[Indika]

Hello, 

I am working on the application where contains the two different styles / themes (Light / Dark) . The user can switch between styles using the toggle button and it will merge the dictionaries. I have two issues which needed to be solved.

1.  I want to change the background colour of the grouped rows in the telerik grid.
2. When you switching between the styles, It will raises an error when is going to filtering the telerik grid. Error : Logical child element already exists. Disconnect it first. 

Could you please let me know, Is telerik supporting customized themes of the applications at the moment ? 

Thanking you

Hello Indika,

As concerned to your first question,you can apply a style for the Grouped rows in the Grouped Event of the RadGridView using the following code (assuming that you have a style named GridViewRowStyle1 which resides in the Resources):

private void gridView_Grouped(object sender, GridViewGroupedEventArgs e)
{
   if (this.gridView.IsGrouping)
   {
         this.gridView.RowStyle = this.Resources["GridViewRowStyle1"] as Style;
         }
         else
         {
               this.gridView.RowStyle = null;
         }
   }
}

Attached is a sample application that demonstrates such a behavior.

As for the second problem - it could be great if you send us a simple application that raises such an error.
