title: How to add bold text to rich text box
body: <p>I'm working with Visual Studio Express 2012 with C#.</p>
  
  <p>I am using code to add text to a <code>RichTextBox</code>. Each time there are 2 lines added. The first line needs to be bold and the second line normal.</p>
  
  <p>Here is the only thing I could think to try, even though I was sure it would not work:</p>
  
  <pre><code>this.notes_pnl.Font = new Font(this.notes_pnl.Font, FontStyle.Bold);
  this.notes_pnl.Text += tn.date.ToString("MM/dd/yy H:mm:ss")  + Environment.NewLine;
  this.notes_pnl.Font = new Font(this.notes_pnl.Font, FontStyle.Regular);
  this.notes_pnl.Text += tn.text + Environment.NewLine + Environment.NewLine;
  </code></pre>
  
  <p>How can I add bolded lines to a rich text box?</p>
  
  <p>Thanks for the answers submitted so far. I think I need to clarify a little.
  I am not adding these 2 lines 1 time. I will be adding the lines several times.</p>
