Hi Kevin,

>Is it possible to tell when the user drops a control onto my user control in design mode?

Events fire in both cases... To try this yourself, add the following code to your project:

	class MyPanel : Panel
	{
		protected override void OnControlAdded(ControlEventArgs e)
		{
			MessageBox.Show("Control added");
			base.OnControlAdded(e);
		}
	}

Build the project, drag MyPanel from the Toolbox onto a form and add any control to the panel by dragging one onto the panel.
