title: Controlling The Number Of Items In Multi Line Textbox
body: <p>I am attempting to Write Products to a Multiline Textbox.</p>
  
  <p>I am writing the information like this:</p>
  
  <pre><code>public override string ToString()
  {
      string output = String.Empty;
  
      output = String.Format("Cust Name {0}" + Environment.NewLine +
                             "Product Name: {1}" + Environment.NewLine +
                             Customer.Name, Name);
      return output;
  }
  </code></pre>
  
  <p>Products are being added one at a time at different times (like a feed).</p>
  
  <p>I want the textbox to only to display the 20 newest Products.</p>
  
  <p>How can I control this?</p>
