Hello Andrew,

We're sorry for the issue you're experiencing.

Could you please give us more details about your scenario and how to reproduce this error? Thanks

Kind regards,

I'm encountering the same error.

I declare a empty context menu with DefaultGroupSettings Height of 100px in html:

<rad:RadContextMenu ID="TreeMenu" runat="server" EnableEmbeddedBaseStylesheet="true" OnClientItemClicked="TreeContextMenuItemClicked_Handler" OnClientShowing="ShowingAddMenu_Handler">
  <DefaultGroupSettings Height="100" />
</rad:RadContextMenu>

In response to a button click, I add items to the context menu using javascript and display the menu (this is a contrived example, but representative of what the code is doing):

function ShowMenu()
{
  var MenuToLoad = $find("<%= TreeMenu.ClientID %>");
  var MenuItems = MenuToLoad.get_items();
  MenuItems.clear();

  var ThisItem = new Telerik.Web.UI.RadMenuItem();
  ThisItem.set_text("Item 1");
  MenuItems.add(ThisItem);

  var ThisItem2 = new Telerik.Web.UI.RadMenuItem();
  ThisItem2.set_text("Item 2");
  MenuItems.add(ThisItem2);

  var ThisItem3 = new Telerik.Web.UI.RadMenuItem();
  ThisItem3.set_text("Item 3");
  MenuItems.add(ThisItem3);

  MenuToLoad.showAt(10,10);
}

The error is generated any time one of the items is clicked in the displayed menu.

I don't know it this will help but make sure you have a radscriptmanager on the page and/or ajax manager

[Seth]

Andrew,

Thank you for the suggestion, but I do have an ASP.NET Script Manager on the page.

Were you able to overcome the error?

Seth

[Andrew]

ya we did but, there was acutally many issues...

I think it had something to do with using the ajaxtoolkit and the telerik toolsin the same site

[Seth]

That would be a major bummer.  The form in question does make use of the AjaxControlToolkit.

Hopefully someone from Telerik can chime in with a suggestion.

Hello Seth,

Could you please try adding a dummy menu item and check if this helps?

<telerik:RadContextMenu ID="TreeMenu" runat="server">
       <Items>
           <telerik:RadMenuItem>
           </telerik:RadMenuItem>
       </Items>
       <DefaultGroupSettings Height="100" />
   </telerik:RadContextMenu>

Kind regards,
