RadPane will not pass its theme to its content. That is the reason scrollbars to have different look rather than the theme. Please, try setting the theme on the ScrollViewer explicitly
, i.e. with an x:Key
Expression Blend is the easiest way for styling the RadDocking
control. It generates all necessary styles and resources and make RadDocking
control easy to modify without deep knowledge of XAML. Please, check the follow online articles for styling the RadDocking control:
Another way for styling RadDocking is to take the resources from the RadControls installation folder on your machine. Inside that folder you will find the Themes folder which contains all themes resources. Just drill down to the Telerik.Windows.Controls.Docking.xaml file and theme of your choice and include those resources in the project.
I hope this will be helpful.
All the best,
the Telerik team
