OnClientMenuItemClicking
The OnClientMenuItemClicking client-side event occurs when the user clicks on a ribbonbar menu item, before the ribbonbar responds to the mouse click.
The event handler receives two parameters:
The instance of the ribbonbar firing the event.
-
An eventArgs parameter containing the following methods:
get_item() returns a reference to the ribbonbar menu item that was clicked. In this case it is RibbonBarMenuItem.
set_cancel() lets you prevent the ribbonbar from responding to the mouse click.
You can use this event to respond when the user clicks on a ribbonbar menu item:
<script type="text/javascript">
function OnClientMenuItemClicking(sender, args) {
var item = args.get_item();
if (item.get_text() == "Flip Vertical") {
args.set_cancel(true);
}
}
</script>
