Hi
I am also having the same problem but the scenario is quite different. I am dynamically attaching ContextMenus with the tree nodes based on different values. These context menus are getting their IDs in the form of random number which is being generated inside the loop in order to differentiate the context menu of one node with the other.
Everything works fine except on iPad. So this solution doesn't work with my scenario. Could you please help me out in sorting out this one?
<telerik:RadTreeView ID="tvCompletedCourses" runat="server" AllowNodeEditing="false" oncontextmenuitemclick="tvCompletedCourses_ContextMenuItemClick">

<Items>
<telerik:RadMenuItem Value="Enter" Text="Enter">
</telerik:RadMenuItem>
<telerik:RadMenuItem Value="Print" Text="Print Certificate">
</telerik:RadMenuItem>
</Items>
<CollapseAnimation Type="none" />
