There's a very simple way to do this. Your requirement is simple since you only have two textboxes.

You can assign a class-wide string variable that holds when textbox1_GotFocus() is invoked as well as textbox2_GotFocus(). So if that textbox GotFocus() is called you assign a value. Then put a condition for the class-wide string variable in the button that if the class-wide variable has a value of thats kind, that textbox is populated whatever you want to put in the textbox.

It worked for me so I believe it should work on you.
