Fortuntately, if there were a known bug that caused this (there's not), it would be with VS .NET, not MM .NET <s>. When you set the BindingSource of these controls you're really just using VS .NET technology to do this. That said, I'd still like to help you get to the bottom of this.

First of all, when you say the BindingSource property was wiped out, did you check the "Windows Forms Designer" generated code section to see what the BindingSource property was set to? Was this blanked out?

Secondly, is it possible these other controls were inadvertently selected when you set the BindingSource of your new controls?
