title: Multiple outputs to a textbox in C#
body: <p>Background:</p>
  
  <p>I am writing a C# form program with MSVS 2010. The form has 2 textboxes: textBox1 (input, single line) and textBox2 (output, multiple lines).</p>
  
  <p>I want to enter a string in textBox1 and when a condition is met it prints some text to textBox2. I want to be able to enter multiple inputs and print output to textBox2 and not erase the previous output. </p>
  
  <p>Questions:</p>
  
  <ol>
  <li>My question is can this be done?</li>
  <li>If not can you use multiple text boxes and move the output to the next higher value text box?</li>
  </ol>
