Answer 1

The easiest way would be create properties that expose the text fields. Call your edit form, then read the properties back.

public class MainForm
{
  private void OnEditClick()
  {
    EditForm editForm = new EditForm();
    DialogResult result = editForm.ShowDialog(this);
    //check the result for ok/cancel etc if your using them.
    whatever = editForm.TextBox1;
    whatever2 = editForm.TextBox2;
}

public class EditForm
{
  public string TextBox1 { get { return textBox1.Text;} }
  public string TextBox2 { get { return textBox2.Text;} }
  // etc
}

You could expose the whole control, but if all you care about is the contents of the text boxes, creating properties to expose just those is cleaner.
