>>>Is Form2 modal? Sounds like it should be. In that case, it has direct access to Form1's controls. They are all still in memory. I think you have to go into the generated part of Form1's code and change their scope from the default of private.

Create a public form method that you call from the other form. Pass a reference from the calling for to the pop-up form via the constructor and save a reference to it. When you need to refresh the calling form just call public method. No need to mess with the generated code. The pop-up form really shouldn't be calling specific controls on the calling form anyway.

If the pop-up is modal, it's even easier. Keep the form as-is and just refresh in the calling form after the modal form call (it will block while the form is open).
