passing data between forms

Mark Gutierrez

Hi, I have 2 child forms inside an MDI form. On the first form is a search button that will launch the search form also inside the mdi form. when I doubleclick the listview control I want the text on the listview control copied on the first form searchtextbox so i can perform the process with it. How can I launch the 2nd form inside the MDI form and how can I pass the data from the second form back to the first form? Thanks

Okay, I'm making an assumption that the ListView control is on your parent form. So here's what you'd do:
1. Define an event on the parent form that will be raised when the ListView is double-clicked
2. When you create the first child form have the parent subscribe to the event for the child (the event handler will be in the child form class definition)
3. Define the event on the second child form to pass back the data
4. When you click the Search button on the first child form you will assign its owner to the first form's parent and the first child form will subscribe to the event defined on the second child form
