Radtreeview, the drop event doesnt fire, only the previewdrop event

[Annett]

Hi,

i have a radtreeview filled with hierarchicaldata. In code i do the settings.

            _radTreeView = projectTreeView._xTreeView;
            _radTreeView.AllowDrop = true;

            _radTreeView.Drop += TreeViewDrop;
            _radTreeView.PreviewDrop += TreeViewPreviewDrop;
            _radTreeView.DragOver += ....

If i drop an item the dropevent doesnt fire. Temporarily i solved this and work with the previewdropevent. But i dont like this solution. Have anyone ideas where my problem is? Some points that i must check?

Thanks
Annett

Hello Annett,

The RadTreeView actually uses and handles the Drag Drop events. Still they can be used for managing the drag and drop process, too. You should use the AddHandler() method of the TreeView with the handledEventsToo parameter set to 'true'. 

public void AddHandler( RoutedEvent routedEvent, Delegate handler, boolhandledEventsToo );

In the API Reference you can see that the Drop event is inherited from System.Windows.UIElement.
