Hi Doug,
You could modify the existing TreeviewAdvDragDrop sample to handle multiple drag-drop of multiple nodes, by placing the following code segment within the TreeViewAdv''s DragOver event handler :
// To prevent drag-dropping on itself
if(this.treeViewAdv1.SelectedNodes.Contains(destinationNode))
{
e.Effect = DragDropEffects.None;
this.treeViewDragHighlightTracker.ClearHighlightNode();
}
The
modified sample containing the above workaround is attached here. Please refer to it and let me know if you have any questions.
