OnClientShown

(RadContextMenu only) The OnClientShown client-side event occurs when the context menu first appears, either in response to a right-click on one of its targets or a call to its show or showAt method.

The event handler receives two parameters:

  1. The instance of the context menu firing the event.

  2. An eventArgs parameter containing the following methods:

  • get_targetElement returns a reference to the DOM element that was right-clicked to show the context menu. If the menu appeared in response to a call to the show or showAt method rather than a right-click on one of its targets, get_targetElement returns null.

  • get_domEvent returns a reference to the DOM event.

You can use this event to initialize the context menu when it appears:

<script type="text/javascript">
    function initializeContextMenu(menu, args) {
        var target = args.get_targetElement();
        if (target)
            menu.get_items().getItem(1).disable();
    }
</script>

<telerik:RadContextMenu ID="RadContextMenu1" runat="server" OnClientShown="initializeContextMenu">
    <Items>
        ...
    </Items>
</telerik:RadContextMenu>
