I use your new XamDataTree control (NetAdvantage 2010.3) in my application.
The DragAndDrop function works fine if I define it in the XAML file.
Unfortunately, the function does not work, however, if I define it in the C# file. 
I have an edit and a view mode in my program. It is therefore important to control the DragAndDrop functionality within the program. Perhaps I have overlooked something and you can give me an advice.

Many thanks in advance.

I have attached an extract of the Xaml-and the c# file.
