title: At runtime, how to update a listview control on a hidden form
body: <p>I got a hidden form (ViewRegisterForm) which has a ListView. This form is hidden, but I want to update the ListView from another form (RegistrationForm) during runtime.</p>
  
  <p>To be honest I am not sure what is the best method to approach this scenario hence I am open to suggestions..</p>
  
  <pre><code>    private void UpdateListView(string value){
          ViewRegisterForm.MdiParent = this;
          ViewRegisterForm.Show();
          ViewRegisterForm.Location = new Point(10, 5);
  
      }
  </code></pre>
  
  <p>Obviously this did not work!</p>
