title: ComboBox's SelectedIndexChanged event not being called on Enter
body: <p>I'm working on VS 2010 with VB using .NET Framework 4.0</p>
  
  <p>I have a <code>combobox</code>. It has some items in it and displays just fine. Here's where it gets a little weird:</p>
  
  <p>If I click the drop-down arrow on the <code>combobox</code> and CLICK on the item I want, <code>SelectedIndexChanged</code> is called - good.</p>
  
  <p>If I click inside the text area of the <code>combobox</code> and start typing what I want selected and finish it by pressing the up (or down) key, <code>SelectedIndexChanged</code> is called - also good.</p>
  
  <p>If I click the drop-down arrow on the <code>combobox</code> and start typing what I want selected and finish it by pressing ENTER, <code>SelectedIndexChanged</code> is not called - PROBLEM.</p>
  
  <p>Is there a different event that is caused by the <code>ENTER</code> in the last case? I've tried using the <code>TextChanged</code> and <code>TextUpdate</code> events, but those do not seem to be working:</p>
  
  <pre><code>Private Sub cmbStatus_TextChanged(sender As System.Object, e As System.EventArgs) Handles cmbStatus.TextChanged
  If e.Equals(Keys.Enter) Then
      Call SomeMethod()
  End If
  </code></pre>
  
  <p>Should I use something besides <code>e.Equals(Keys.Enter)</code>?</p>
  
  <p>Is there another event I should be looking for?</p>
  
  <p><strong>EDIT:</strong>
  An example of the items in the <code>ComboBox</code> are:</p>
  
  <ul>
  <li>10 - NEW ENTRY AND COMPLETENESS CHECK            <code>---&gt; this is the most common type</code></li>
  <li>13 - ASSIGNED TO TRB/HRB                         <code>---&gt; there are a few with '/'</code></li>
  <li>60 - EXTERNAL (HOLD UNTIL FURTHER NOTICE)        <code>---&gt; there are a few with '(' and ')'</code></li>
  </ul>
  
  <p>Basically, the type of each listing is "## - SOME TEXT".</p>
