title: Passing Data back to First Form from Second Form and a class using delegates in C#
body: <p>From FormA I call FormB using <code>frmB.Show();</code></p>
  
  <p>In FormB, I have two textboxes. Assume User enters some data in those two textboxes.
  I need to add this to a ListBox on FormA.</p>
  
  <p>To achieve this I have created a delegate instance and called it in FormA after creation of frmB object - which works fine.</p>
  
  <p>In FormB, Class1 object is created and one of its method is called which also needs to access/update the ListBox in FormA.</p>
  
  <p>I can't create an instance for Class1 in FormA as Class1 instance is created in FormB. I tried to assign Class1 delegate instance to FormB instance but it is not working. </p>
  
  <p>How can I achieve this ?</p>
