Refresh Main form after closing sub form

Question

I have a form F1. In this form F1 a method called Refreshthisform() is written by me.

when i press a button in F1, form F2 opens. after performing some transcations, wheni close F2, i want the method RefreshthisForm() in F1 has to be invoked and refreshed.

to be simple, F1 has a method which should invoke when i close F2.

Can some one help me with a sample code

There are many ways you could handle this. One way would be: // this is just pseudocode Form1 btnClick { Form2 form2 = new Form2(this); form2.Show(); } public void RefreshForm() { } Form2 Form1 form1; public Form2(Form1 form1) { this.form1 = form1; } form_closing { form1.RefreshForm(); } Form2

Form 1 is the main form. When a button is clicked in form1 form 2 is opened keeping form1 also in opened state. now after the changes made in form2 if we close form2 then in form1 there is a method called refreshthisform() which should be invoked(or) called. the event for form 2 is form2_closing. in this event i have to invoke a function(or) method called refreshthisform() of form1

Is F2 a modal dialog form? Form1 private void call Form2() { Form2 form2 = new Form2(); form2.ShowDialog(); //this call blocks unless form2 is closed. RefreshForm(); // call your refresh function } If instead Form2 is not modal dialog you need to introduce an event in Form1 pass that event onto Form2 and trigger that event upon closing form2
