I followed the example in the documentation help file(ms-help://telerik.radcontrols.prometheus.2007.Q3/telerik.radcontrols.prometheus.2007.Q3/tree_ContextMenuOverview.html) to display Add and Delete on a right-click. If I add a new node so that it's text is "New node" and then double-click to edit the text to anything else, when I add another new node, it creates the new node with text "New node", but also resets the text of the node I just edited back to "New node".
This can easily be duplicated in your online demo at http://www.telerik.com/DEMOS/ASPNET/Prometheus/TreeView/Examples/Functionality/ContextMenu/DefaultCS.aspx.
Right-click on "Public Folders" and select "New Folder". Then double-click and change the text to "My Folder". Now, right-click again on "Public Folders" and select "New Folder". There are now two folders named "New Folder" instead of one named "My Folder" and one named "New Folder".
