Hello all. I try to use RadTreeView but I can't  catch events: PreviewDrop and Drop. But PreviewDragStarted and other Drag events I catch. And UI works successfully.

Hello Alexander,

The TreeView does not use the built-in WPF DragDrop and it relies on our own implementation with the RadDragAndDropManager, mainly because of code compatibility with Silverlight.

The Drop and PreviewDrop events are inherited from the base visual classes and are not used.

The PreviewDragStarted and Drag events respectively are TreeView's own events and are used.

If you need, with some code, you can use the built-in WPF DragDrop as well, but the treeView does not by default.

I noticed that you have submitted bug report as well, I will reply in more detail there once I have a look at your code.

All the best,
Miroslav
