To learn how to style RadPropertyGrid and any of our WPF controls, you can read the common topic about Setting a Theme (Using Implicit Styles)
There is also another way to obtain the template of a particular visual element. In the RadControls installation folder on your PC, go to Themes folder ( Themes.Implicit in case you're using Implicit Styles
) and select the theme that you use in your application. Then drill down to find the respective Telerik.Windows.Controls.Data.xaml
file in that directory. From this resource dictionary you can extract any needed resources.
I hope this helps.
