Most controls in .NET forms don't use a containership-model (like VFP does). All controls are actually just properties added to the form, even if they appear "inside" another control. (NOTE: that's not absolutely true everywhere); take a look at the code in the .designer files to see this. Another stumbling point is that, inside of a delegate (event), Me/this usually doesn't refer to the control that raised the event. That's why the event signature usually passes the source of the event as the first parameter.
