StartMenu events?

Hello, George,

According to the provided brief information, I suppose that you are trying to detect clicking the application menu button:

The RibbonBarElement.ApplicationButtonElement property gives you access to the button element. You can subscribe to its Click event.

            this.radRibbonBar1.RibbonBarElement.ApplicationButtonElement.Click+=ApplicationButtonElement_Click;

        private void ApplicationButtonElement_Click(object sender, EventArgs e)
        {
            Console.WriteLine("click");
        }

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
