I have a UserControl that has in it a TableLayoutPanel. I activate ControlAdded event that adds the controls added in the UserControl to the TableLayoutPanel:

The problem is that at DesignTime when I'm trying to add a control to my new UserControl, the VisualStudio 2005 crashes.
If I have another UserCOntrol that inherits from it i get this error: 'child' is not a child control of this parent

Can anyone give me some sample code that solves this problem?

Thanks

That event you postedis firing off when you add the controls. I'd bet oneobject or the other could be null. Try setting a breakpoint in that method.

Does it work as you expect at runtime? I would imagine not, but based on what you've said it appears I might be wrong.

If you are trying to prevent a control from being added to the form, and instead have it added to the TableLayoutPanel, you should override the OnControlAdded event, rather than putting this code in an event handler.

If, for whatever reason you need to stick with the design you've shown, you could try to wrap the tableLayoutPanel1.Controls.Add(e.Control); line in an If(Designmode = True) or If(Debugger.Attached = True) clause.
