title: Get the name of the button that triggered the event
body: <p>I have an event handler that handles the click event of multiple buttons: </p>
  
  <pre><code>Private Sub primeHandler(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles _2s.Click, _3s.Click, _4s.Click, _5s.Click, _6s.Click
  
  End Sub
  </code></pre>
  
  <p>_2s, _3s, etc are all buttons.
  Now I need a way to determine which button triggered the event and also get the button's name <strong>as string</strong>. Any way to do that? Thanks</p>
