Hello David,

You can listen for the PreviewDragStarted event and do the following:

private void treeView_PreviewDragStarted(object sender, RadTreeViewDragEventArgs e)
{
    foreach (object item in e.DraggedItems)
    {
        if ((treeView.ItemContainerGenerator.ContainerFromItem(item) as RadTreeViewItem) != null)
        {
            e.Handled = true;
        }
    }
}

This should achieve your purpose. Let me know if you have further questions.

Sincerely yours,
