I have a small problem.
In my web project I have one modal form, for examplo, called F1, with one textfield txTotal;
F1 calls F2 (another modal webform).
when I close F2 I would like to call one method in F1 to update txTotal; but I receive this error:
F2.btClose.Action, line 50
Static reference to instance method: call this on an instance of class F1.F1.
