C# Winforms .Net - Dynamic Communication Between Two Forms

Question

I've two froms which need to communicate simultaneously. When certain element in FORM B is clicked, FORM A is shown and some operation is performed. But the foreach loop inside FORM B should work when i click some next button in FORM A after the first operation.

Answer 1

Can you modify the constructor of your FormA

public FormA(Form F1)
{
   InitializeComponent();
   formB = frm as FormB;            
}

Show the form from FormB as

FormA frmA = new FormA(this);
frmA.Show();

Now you have a reference of FormB in FormA. Now expose the loop logic in a public method which could be accessed by this instance of FormB

Hope this helps.

Answer 2

Another option is to create your own events in FormB and subscribe to them in FormA here is a few examples:

Also here is a greate sample about how to do this:

Note also,while what V4Vendetta offered would be the easy way to do this-this however is probably the better way to do this,and also a better practice.
