how to refer to the form that caused: form2.show

how to refer to the form that caused: form2.show

  Same situation for ShowDialog(). ShowDialog is not much more than a Show() that temporarily takes over the main thread of the application until the modal dialog is closed.

  There is no built-in knowledge of what form caused another form to show... after all, pretty much any code could have shown the Form2, not just something within Form1.

  If you really need this association, then the easiest thing would be to add a public property to Form2 (call it "ShownByForm" for example). Then set this property just before showing the form...

  public partial class Form1 : Form

  {

  /*...*/

  public void ShowForm2()

  {

  Form2 FormToShow = new Form2();

  FormToShow.ShownByForm = this;

  FormToShow.Show();

  }

  }

  public partial class Form2 : Form

  {

  /*...*/

  private Form _shownByForm = null;

  public Form ShownByForm

  {

  get { return _shownByForm; }

  set { _shownByForm = value; }

  }

  }

  How do I get a reference to form1.

  Neither using parent nor owner in form2 has worked for referencing the form that instantiated the current form with:  form2.show

  THnaks.
