Hi, I am trying to convert my DataGrid to a RadGridView and I get the following error

 

System.Reflection.TargetInvocationException

Hi,

You have styles associated with standard Silverlight DataGrid - not with RadGridView. Please fix your styles!

Greetings,

What is the TargetType for the HeaderCellStyle or how can I change this cell header style?

Nevermind I found it : Telerik.Windows.Controls.GridView.GridViewHeaderCell
