If he/she confirms then only he can able to add a new child node . For this I have written the bellow mentioned code . It is working for when user is confirms but it not working when user not confirming it . It is giving error at
"args.set_cancel(true);" . Can you please help me out .
function
onClientContextMenuItemClicked(sender, args)
{
var menuItem = args.get_menuItem();
var treeNode = args.get_node();
if (!confirm("Do you really want to add a new value. ? "))
{
args.set_cancel(
true);
}
else
{
switch(menuItem.get_value())
{
case "NewValue":
break;

Attach the function to OnClientContextMenuItemClicking event of RadTreeView instead of OnClientContextMenuItemClicked. The OnClientContextMenuItemClicking client-side event occurs when the user clicks a menu item, but before the OnClientContextMenuItemClicked event fires, and performing any action for contextmenuitem click and can be canceled.
Thanks,

Thanks for your reply . I used the OnClientContextMenuItemClicking event earier , but issue was when you don't confirm the message still the context menu item was displaying , if you clicked outside once then only the context menu item is removing . Can you suggest me what should I do in this case .

Canceling the OnClientContextMenuItemClicking means that the click on the menu item is canceled. It does not mean the menu would close. You can close it by yourself (using the hide() or close() javascript methods).
I hope this helps.
