As I mentioned in the question, I am trying to create a button and I wanna use this button in all forms.
I checked MDI application but something is wrong with it. I tried to use interface but it worked only the main form not in childform.
Kind Regards
I think there is a way: in the button you can call the
DoWorkmethod of form and you can makeDoWorkas you want in different forms.in this way you can get the reference of all forms in central form and in the
ButtonClickEventyou can callDoWorkmethod of the forms.
