Prevent Auto-Expand of Nodes during Drag and Drop?

[Richard]

Hi,

The Drag-and-Drop example between a RadTreeView and a RadGrid works fine, but we need to lock-down the TreeView while the user drags to the RadGrid. You see, if the TreeView is large, and the user drags one of the top nodes slowly across the TreeView, then it is quite annoying for the TreeView to expand all the nodes while dragging... I've disabled "Dropping" on the TreeView, but that has no effect on the Expand mode, of course. Any tips on how to elegantly disable ExpandMode while dragging a node?

Thanks!

Hi Richard,

Attach the OnClientNodeExpanding event to RadTreeView and cancel the event if you are dragging a node.

javascript:

<script type="text/javascript">
    function OnClientNodeExpanding(sender, args) {
        if (sender._dragging) {
            args.set_cancel(true);
        }
    }
</script>
