OnClientContextMenuItemClicked And Return Confirm

[Inge Wandsvik]

I have a RadTreeView (RadControls Ajax Q1 2008 1.415) with ContextMenu. When I click an item in the ContextMenu called "Delete", I want to show a confirm messagebox. What happens now is that it run a postback no matter what (the ContextMenu item has PostBack=true), but I want to stop this if the user clicks "Cancel" in the confirm messagebox.

Here is my javascript function (called from OnClientContextMenuItemClicked):

    function onClientContextMenuItemClicked(sender, args)
    {
        var menuItem = args.get_menuItem();
        var treeNode = args.get_node();

        switch(menuItem.get_value())
        {
            case "Edit":
                break;
            case "Delete":
                return confirm('Are you sure?');
                break;
        }
    }

Anyone with a solution?

Hello Inge Wandsvik,

You need to subscribe to the OnClientContextMenuItemClicking instead of OnClientContextMenuItemClicked.

To cancel the event you can use:

eventArgs.set_cancel(!confirm('Are you sure?'));

I hope this helps.

Can you do this with the radconfirm I tried this and it just posts back is there an example of this with the rad confirm??

Hello Matthew Todd,

Unfortunately, this cannot be easily achieved and might lead to some side effects. I would rather suggest that you use the standard confirm method instead to cancel the postback.
