What is the error .& how to solve this problem...P

first the link u have provided is not working

try to copy and paste ur markup to help u

but any way try to check with me the syntax here:

<atlas:ScriptManager runat="srever" ID="scriptManager1" EnablePartialRendering="true"/>

<atlas:UpdatePanel runat="srever" ID="updatePanel1" Mode="Always" >

<ContentTemplate>

//here u add ur controls

</ContentTemplate>

</atlas:UpdatePanel>

or if u make it conditional mode

<atlas:ScriptManager runat="srever" ID="scriptManager1" EnablePartialRendering="true"/>

<atlas:UpdatePanel runat="srever" ID="updatePanel1" Mode="Conditional" >

<ContentTemplate>

//here u add ur controls

</ContentTemplate>

<Triggers>

// here u add ur triggers may be upon event or a change in property as u wish

</Triggers>

</atlas:UpdatePanel>
