title: Linkbutton Click not working in update panel
body: <pre><code>&lt;div id="TrainingSearchGridContainer" class="mt_20"&gt;
     &lt;asp:UpdatePanel runat="server" ID="UpdatePanelCountryRegions" UpdateMode="Conditional"&gt;
                      &lt;ContentTemplate&gt;
  &amp;nbsp;
  &lt;asp:DropDownList runat="server" ID="ProductDropDown"&gt;&lt;/asp:DropDownList&gt;
  &lt;asp:DropDownList runat="server" ID="DateDropDown"&gt;&lt;/asp:DropDownList&gt;
  
  &lt;asp:DropDownList runat="server" ID="CountryDropDown" AutoPostBack="True" OnSelectedIndexChanged="LoadRegions"&gt;&lt;/asp:DropDownList&gt;
  &lt;asp:DropDownList runat="server" ID="StateDropDown"&gt;&lt;/asp:DropDownList&gt;
      &lt;asp:LinkButton ID="SearchBtn" runat="server" OnClick="StartSearch"&gt;
      &lt;span class="blueButton2css3"&gt;&lt;span class="btnspan"&gt;
          &lt;asp:Literal ID="SearchButtonText" runat="server"&gt;&lt;/asp:Literal&gt;&lt;/span&gt;&lt;/span&gt;
  &lt;/asp:LinkButton&gt;
  &lt;/ContentTemplate&gt;
      &lt;Triggers&gt;
   &lt;asp:asyncpostbacktrigger controlid="SearchBtn" eventname="Click" /&gt;
  </code></pre>

  </p>
  
  <p>But for some reason when I click on the button nothing happens, If I remove the update panel the button works fine.</p>
