title: Send values from one form to another form
body: <p>I want to pass values between two Forms (c#). How can I do it?</p>
  
  <p>I have two forms: Form1 and Form2. </p>
  
  <p>Form1 contains one button. When I click on that button, Form2 should open and Form1 should be in inactive mode (i.e not selectable).</p>
  
  <p>Form2 contains one text box and one submit button. When I type any message in Form2's text box and click the submit button, the Form2 should close and Form1 should highlight with the submitted value.</p>
  
  <p>How can i do it? Can somebody help me to do this with a simple example.</p>
