Could you please give some more information about the exact problem you are facing and which version of the controls you are using? I'm attaching a sample project here which demonstrates the approach of using the CanDropOnTabStrip property with the PreviewShowCompass event in order to prevent dropping on the tabs.
I'm looking forward to your reply.
