Disable top menu item?

[Josh]

Top Menu Item
    - Action A   
    - Action B

I've got a radmenu, using onitemclick to handle events on the server - is there anyway to disable postback for the top menu item so there is only post back when clicking one of the items? Can't seem to find an easy solution for this...

Hello Josh,

Thank you for writing to us.

There are two ways of accomplishing this:

1. Set the PostBack property to false of those Items which you do not want to do a postback upon clicking:

   <telerik:RadMenuItem Text="Text" Value="Value" PostBack="false"></telerik:RadMenuItem>

2. Handle the OnClientItemClicking client-side event and cancel the event if the clicked Item is a root Item (canceling the OnClientItemClickcing event will prevent the postback):

           function OnClientItemClicking(sender, eventArgs)
           {
               var item = eventArgs.get_item();
   
               var rootItems = sender.get_items();
   
               if (rootItems.indexOf(item) > -1)
               {
                   eventArgs.set_cancel(true);
               }
           }

You could read more about the client-side functions and events used here:

• RadMenu and RadContextMenu objects
• RadMenuItemCollection object
• OnClientItemClicking

I have also attached a sample project which demonstrates both approaches described above.

I hope this helps.
