The great control in the asp.net ajax is the update
panel control.it can be added to almost every
asp.net page almost magically.this control when
used with a ScriptManager permits a programmer to
use partial rendering(a technique by which many
sections of page updated partially without reloading
the entire page).

following is a simple example wrapping a GridView in an
UpdatePanel control -

<asp:ScriptManager runat="server" ID="ScriptManagers"
EnablePartialRendering="True" />

<h1>Gridview data:</h1>
<p>Page rendered at <%= DateTime.Now.ToLongTimeString() %>.</p>
<asp:UpdatePanel runat="server" ID="TheUpdatePanel">
<ContentTemplate>
<asp:GridView id="Grid" runat="server"
AllowPaging="True" PageSize="10"
onpageindexchanging="Grid_PageIndexChanging">
</asp:GridView>
<p>Grid rendered at <%= DateTime.Now.ToLongTimeString() %>
</p>
</ContentTemplate>
</asp:UpdatePanel>

in the above codes The UpdatePanel allows the content
within its <ContentTemplate> tags to be updated using Ajax
without reloading the page.
