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?
