title: How to show existing form from another form?
body: <p>i have Form1 and Form2, in Form1 i have some textboxes like username,password and more... and a textbox "region". when user hits "region"(Form1.hide()), then Form2 opens witch has 5 labels with names of regions on it. </p>
  
  <p>so how can i make that when user clicks on a name of region in Form2, Form1 will have the region on it? and keep all the data that the user entered before the region click.</p>
  
  <p>something like this(in form 2):</p>
  
  <pre><code>private void center_Click(object sender, EventArgs e)
      {
          this.Hide();
          Form1.region = "center";
          Form1.show();
      }
  </code></pre>
