<pre><code>        &lt;iframe 
            runat="server" id="Iframe2" height="565" width="100%"   scrolling="no" 
            style="overflow-x:hidden;" frameborder="0" marginheight="0" marginwidth="0" 
            vspace="0" hspace="0"&gt;                
        &lt;/iframe&gt;  

     &lt;asp:HiddenField ID="hdfIndex" runat="server" /&gt;                         
     &lt;/ContentTemplate&gt;
            &lt;Triggers&gt;
                 &lt;asp:AsyncPostBackTrigger ControlID="ibtnPrevious" EventName="Click" /&gt;
                 &lt;asp:AsyncPostBackTrigger ControlID="ibtnNext" EventName="Click" /&gt;
                 &lt;asp:AsyncPostBackTrigger ControlID="ibtnPage1" EventName="Click" /&gt;
                 &lt;asp:AsyncPostBackTrigger ControlID="ibtnPage2" EventName="Click" /&gt;
                 &lt;asp:AsyncPostBackTrigger ControlID="ibtnPage3" EventName="Click" /&gt;
                 &lt;asp:AsyncPostBackTrigger ControlID="ibtnPage4" EventName="Click" /&gt;
                 &lt;asp:AsyncPostBackTrigger ControlID="ibtnPage5" EventName="Click" /&gt;
            &lt;/Triggers&gt;
</code></pre>

<p>But when I use it without iframe then it works nicely.</p>
