MDI - ShowDialog alternative ***Resolved***

[LIPAE]

I have a MDI form that opens a child form (called form1). On this form I want to be able to open another form (Called form2). (Which is also a child form). Once the new form is opened I want the code execution to halt for form1 until form2 is closed. The showdialog function does this but it cannot be done from a child form. Is there any way around this?

The reason I want to do this is so that when form2 comes up i can enter data and then when form2 is closed I can call a method to refresh a combo box on my form1.

Any help will be much appreciated.
