title: TextBox Events in C#
body: <p>I have a TextBox. After leaving the textBox the first character should be a capital Letter.
  Three Events work as same. They are Leave,Validating and Validated.</p>
  
  <pre><code>if (txtLocl.Text.Length &gt; 0)
      txtLocl.Text = txtLocl.Text.Substring(0, 1).ToUpper() + txtLocl.Text.Substring(1); 
  </code></pre>
  
  <p>Which event of these 3 events should I use?</p>
