title: run postback for UpdatePanels
body: <p>I have a jquery modal that is being called from a button on my page. When the Webmethod for this button is called, and all logic is complete, I need to refresh several update panels on my page, to reflect the changes that took place in the WebMethod.</p>
  
  <p>I've not used Update Panel much, but i've followed a view examples and am drawing a blank.</p>
  
  <p>In the success portion of my call, i've placed this:</p>
  
  <pre><code>    success: function (msg) {
           $('#ApproveDialog').modal('hide');
           __doPostBack("&lt;%= UpdatePanel1 %&gt;","");
  </code></pre>
  
  <p>and my update panel is:</p>
  
  <pre><code>       &lt;asp:Button ID="button" runat="server" style="display:none;"/&gt;
          &lt;asp:UpdatePanel runat="server" ID="UpdatePanel1" UpdateMode="Conditional"&gt;
              &lt;ContentTemplate&gt;
                  &lt;asp:GridView ID="grdMessageDate" runat="server"/&gt;                &lt;/ContentTemplate&gt;
              &lt;Triggers&gt;
                  &lt;asp:AsyncPostBackTrigger ControlID="button" EventName="Click"/&gt;
              &lt;/Triggers&gt;
          &lt;/asp:UpdatePanel&gt;
  </code></pre>
  
  <p>I've left out part of the Grid, but i have a button in the first col, which is used to display further information.</p>
  
  <p>When i click the button in the grid. this is causing the postback.</p>
  
  <p>How do i call the postback in the success method?</p>
