hello

I get a NullReferenceException when doing this:

RadDragAndDropManager.SetAllowDrag(this, true);

 


I tried with:

 

RadDragAndDropManager.SetAllowDrop(this, true);

 


This is working fine

I also tried:

this.SetValue(RadDragAndDropManager.AllowDrag,true);

This line crash as well

Does anybody have an idea?

I found the solution


following a bad management of our splash screen, it appeared that Application.Current.MainWindow arrived null

this caused a Telerik internal function to scrash

I just set it to the main page of the application and it went right



I suggest that Telerik make a specific test in order to get a cleaner error message
