title: control.focus() after selectedIndexChanged
body: <p>I need to focus on a textbox after an item has been selected from a dropdownlist.</p>
  
  <p>I've tried control.focus() and setfocus().</p>
  
  <p>The last thing I've tried was Set_Focus(dtbEffectiveDate.ClientID) inside the SelectedIndexChanged method with the folowing method.</p>
  
  <pre><code>Protected Sub Set_Focus(ByVal ControlName As String)
      Dim strScript As String
  
      strScript = "&lt;script language=javascript&gt; window.setTimeout(""" + ControlName + ".focus();"",0); &lt;/script&gt;"
      RegisterStartupScript("focus", strScript)
  End Sub
  </code></pre>
  
  <p>I'm out of answers so any help would be awesome.</p>
