context menu on a usercontrol?

I've written a usercontrol that, in essence, is a palette of widgets. When the user right-clicks on one of the widgets that I've drawn on the control, I want to allow the user to delete the selected widget.

In the MouseClick event handler of my usercontrol, I determine which widget the user has clicked on. I then check to see if the mousebutton is the right button. If so, I display a menu that should allow the user to delete the widget:

if (e.Button == MouseButtons.Right)
{
    ContextMenu deleteMenu = new ContextMenu();
    MenuItem deleteItem = new MenuItem("Delete...", new System.EventHandler(this.onDeleteMenuItem_Click));
    deleteMenu.MenuItems.Add("Delete");
    deleteMenu.Show(this, new Point(mouseXPosition, mouseYPosition));
}

My handler for this item is:

private void onDeleteMenuItem_Click(object sender, EventArgs e)
{
    System.Diagnostics.Debug.WriteLine("Deleting...");
}

When I right-click, the menu is displayed, but the handler never gets called. What am I doing wrong?

I suspect it is because you are not adding the menu item:

Change this line of code:

deleteMenu.MenuItems.Add("Delete");

to:

deleteMenu.MenuItems.Add(deleteItem);
