hi, i'm triyng to edit the style of the radpanegroup, i want to edit the background header.. (like in the attached screenshot) but there is a problem: if i declare a telerik windows 7 theme, i lost the customized style of the rad panegroup..when i move the radpanegroup, the style become the default. Instead, if i don't use    any theme, the style work perfectly. here is the link with the small project zipped:  http://www.fileserve.com/file/c6wsFJT/dock.zip

Hi Marco,

When you set a style to the RadPaneGroup, it basically overrides the theme, if any.
I suggest you use the resources directly from the Windows7 theme and apply any customizations to that particular RadPaneGroupStyle.

Also, when you take the pane group out of the normal flow of RadDocking, it becomes a ToolWindow. To customize the header of the dragged pane group, you need to customize the ToolWindowStyle. You can check more details here.

I hope this helps.
