Have you looked for a click event? http://msdn2.microsoft.com/en-us/library/system.windows.forms.menuitem.click(VS.71).aspx[^]
MenuItem childrenItem = new MenuItem((string)childItem["ProductName"]); chilrenItem.Click += new System.EventHandler(this.menuitem_click); private void menuitem_click(Object sender, System.EventArgs e){ //respond to the click event }Mark's blog: developMENTALmadness.blogspot.com

I've never heard of a the Menu class. I've heard of MainMenu, MenuStrip, ContextMenu, ToolStrip, but not that. Anyway, if its anything like the previous three components, you can capture the click events on the items themselves like someone already mentioned. Or you can handle the MenuItemsClicked event of the menu. Heres an example from a toolstrip:
ToolbarControl.ItemClicked += new ToolStripItemClickedEventHandler(ToolbarControl_ItemClicked); private void ToolbarControl_ItemClicked(object sender, System.Windows.Forms.ToolStripItemClickedEventArgs e) { //Get the name of the item clicked switch (e.ClickedItem.Name) { case "Item1": DoWork(); break; case "AnotherItem": DoSomethingElse(); break; } } -
