Is there a way to prevent users dragging and dropping nodes in the Tree.
I have a tree which prevents dragging and dropping but when you click a node (mouse down) and drag the node (mouse still down) the node selected does not move but any node that is under the mouse pointer is highlighted.
This probably seems a little counter-intuitive, but you need to set:
this.ultraTree1.Override.SelectionType = Infragistics.Win.UltraWinTree.SelectType.SingleAutoDrag;
In this case, AutoDrag refers to automatically dragging nodes, so it will not drag the selection. It doesn't actually automatically drag nodes, either, it just fires the SelectionDrag event.
Thanks. It fixed it.
