Preserve the state of multiple forms

Hi all

I am designing an application where the user can enter information on different forms that are accessed from a main window. Each form contains a combination of text boxes, radio buttons, etc.

The problem I am having is that if the user closes the form (using the standard X button at the top of the form) and then loads it again from the main window, the form returns to its default values and doesn't save the values that the user entered.

I did consider using tabs instead of separate forms, but there will be situations where the user will want to compare the entries on several forms simultaneously.

So, is it possible (without having to write code to store all the variables and reload them) to save the state of the form when it has been closed and reproduce the user's entries when it is opened again?

P.s. I am quite new to visual studio programming.

Thanks in advance.
