Problem with a PropertyGrid field

Hi,
I'm implementing a tool which has to manage a lot of objects. The user can select some objects simultaneously and modify the properties in a PropertyGrid. Each object has a Name which has to be unique. In Visual Studio's GUI builder if the user selects some controls simultaneously the (Name) property disappears from the PropertyGrid for avoiding to assign the same name to some controls. ¿Somebody knows how it could be implemented this behaviour in my tool?

thanks.
