title: Difference between AsyncPostBackTrigger and PostBackTrigger on UpdatePanel?
body: <p>I have a <code>GridView</code>(ucLAD) in my <code>UpdatePanel</code>(upnlListing). Inside my <code>ucLAD</code> I have a checkbox and an action for <code>rowClicked</code>:</p>
  
  <pre><code>&lt;asp:UpdatePanel ID="upnlListing" runat="server" &gt;
       &lt;Triggers&gt;
          &lt;asp:AsyncPostBackTrigger ControlID="ucLAD"/&gt;
          &lt;%-- &lt;asp:PostBackTrigger ControlID="ucLAD"/&gt; --%&gt;
       &lt;/Triggers&gt;
       &lt;ContentTemplate&gt;
          &lt;asp:Panel ID="pnlRequest" runat="server" style="margin-top:15px; height: auto;"&gt;
               &lt;ucgv:BaseGrid runat="server" ID="ucLAD"/&gt;
          &lt;/asp:Panel&gt;
  
       &lt;/ContentTemplate&gt;  
  &lt;/asp:UpdatePanel&gt;
  </code></pre>
  
  <p>When I use the <code>PostBackTrigger</code> the action performed would be the <code>rowClicked</code> same thing happen when I check the checkbox but when I use the <code>AsyncPostBackTrigger</code>, I can check the checkboxes but when I click the row, the action for <code>rowClicked</code> don't trigger. How can I fix this?</p>
