OnClientItemClicked

The OnClientItemClicked client-side event occurs when the user clicks on a menu item, after the menu responds to the mouse click.

The event handler receives two parameters:

  1. The instance of the menu firing the event.

  2. An eventArgs parameter containing the following methods:

  • get_item returns a reference to the RadMenuItem that was clicked.

  • get_targetElement (RadContextMenu only) returns a reference to the target element attached to the context menu that is responsible for the context menu showing.

  • get_domEvent returns a reference to the DOM event that caused the clicking.

You can use this event to respond when the user clicks on a menu item:

<script type="text/javascript">
    var clipboardEmpty = true;
    function copyPasterItemClicked(sender, args) {
        var clipboardElement = $get("hdClipboard");
        var itemValue = args.get_item().get_value();
        if (itemValue == "Cut") {
            clipboardElement.value = args.get_targetElement().value;
            args.get_targetElement().value = "";
            clipboardEmpty = false;
        }
        if (itemValue == "Copy") {
            clipboardElement.value = args.get_targetElement().value;
            clipboardEmpty = false;
        }
        else if (itemValue == "Paste") {
            args.get_targetElement().value = clipboardElement.value;
        }
    }  
</script>
