Telerik team,

I am using OnClientNodeEditing event of radtreeview to rename the node. I am also updating the database from the client side.
I am getting a weird problem. Whenever I rename the node and after then any server side event gets call the node get the previous text i.e. the text which was before renaming.

I don't want to post back for simple action like renaming the node.
Please let me know the cause and resolution for such behavior of the radtreenode.

Any help will be appreciable.

Regards,
Sampada

Hi Sampada,

Could you send the code for the OnClientNodeEditing event, so that we can get a better understanding of your logic in order to reproduce the issue.

Following is my code to rename the radtreenode :

function trvNodes_onNodeEditing(sender, args) {
            var parent = new Telerik.Web.UI.RadTreeNode();
            parent = args._node.get_parent()
            var flag = true;
            var allNodes = parent.get_allNodes();
            
            if (args.get_newText().trim() == "") {
                flag = false;
                args.set_cancel(true);
            }
 
            if (flag) {
            //folowing method update the database entry from client side.
                RenameNode(args._node.get_value(), args.get_newText());
            }
        }

After renaming node if I add new node in treeview from server side.
The new node name went and old node name appears.
I am not rebinding radtreeview while adding node.

Hi Sampada,

Try adding the following line in the beginning of the trvNodes_onNodeEditing function:
sender.trackChanges();

Then add a handler for the OnClientNodeEdited event and write the following line inside it:
function onClientNodeEdited(sender, args) {
    sender.commitChanges();
}

This should solve the issue.
