I'm new to using Telerik ASP.net AJAX treeview control. The problem I'm
facing is whenever I do a nodeEdit it does fires the code behind
RadTreeView1_NodeEdit event but, when the page reappears it will have 2
treeview controls. One having the old data and the other having the new
updated data. I'm updating the database table and repopulating the tree
when the database write is complete.
Please let me know how to solve this issue.
Thanks
