I would like to determine the index of the selected context menu item. But I don't want to build a unique eventhandler for each menu item...how do I do this
MenuItem开发者_高级运维 mi= StatusContextMenu.MenuItems.Add("Set option");
mi.MenuItems.Add(0,new MenuItem("Set to A", new EventHandler(SetLetter)) );
mi.MenuItems.Add(1,new MenuItem("Set to B", new EventHandler(SetLetter)));
mi.MenuItems.Add(2,new MenuItem("Set to C ", new EventHandler(SetLetter)));
mi.MenuItems.Add(3,new MenuItem("Set to D", new EventHandler(SetLetter)));
private void SetLetter(object sender, System.EventArgs e)
{
index = ????
}
C#, .net 2.0
You can cast the "sender" parameter (cast to MenuItem) to find the index in the mi.MenuItems collection.
Alternatively, I would set-up the event handlers using anonymous functions...
E.g.
mi.MenuItems.Add(0,new MenuItem("Set to A", (s, e) => SetLetter("A"));
Then you've got SetLetter as:
private void SetLetter(string letterToSetTo)
{
}
