    I have two three views. One has hierarchical data and the other is flat data. is there a way to disable dragging and droping group items into the flat treeview?

    Hi mher,

    I guess by "group" item you want to indicate an item that has child items. If so, you can examine the attached project where a basic approach is realized. It uses the PreviewDragStarted event of the source tree and stops the drag operation if the dragged item has children. Please let us know if this helped you.

    All the best,
