>>To control the drag and drop behavior I suggest you use the EnableDragAndDrop property of RadTreeView.
That's what I tried first, but it doesn't work dynamically either. If I put:
RadTreeView2.EnableDragAndDrop = true;
in a callback (i.e. anywhere besides the page initialization), it doesn't work. Any ideas?
After taking a closer look at the Ajax traffic (I'm using ServerCallback mode), it appears that you are sending the ViewState down to the server in the POST, and returning JSON that contains only the node content and some settings like this:
}]_$$_<li class="rtLI"><div class="rtTop rtSelected"> ...
That is great for performance, but these settings are apparently not transported for all nodes or not for the TreeView itself? In any case, the ones I set are apparently not being applied client-side... and it doesn't look like they are present anywhere in the client-server communication.
