            // Ensure that the view is set to show details.
            listView1.View = View.Details;            

            // Create column headers for sorting the listview data. 
            ColumnHeader IDHeader, FirstNameHeader, LastNameHeader, HomePhoneHeader, CellPhoneHeader, CountryHeader, ZipCodeHeader, CityHeader, StreetHeader, EmailHeader;
            IDHeader = new ColumnHeader();

The simple answer to your problem is to create a populating method in Form 2 to put any data you want to appear into the form. You also add a delegate and an event to fire upon adding the new information which will return any data you changed into the record you were editing. I won't write code for your homework but the pseudocode would be:

Form 1

Create Form2 variable

instattiate form2 variable
form2.event += method to update record;
form2.show


method to update record(var 1, var 2, var 3, etc.)
{
record.var = var1;
etc.

form2.event -= method to update record;
}


Form 2
delegate with structure that includes all variables to update

event of type of above delegate

when button apply is clicked
{
  event(var 1, var 2, var 3, etc.)
}
