Update panel is a server control. It is used to update specified portion of a web page. To use update panel, we need to use a script manager.

in aspx page

<asp:ScriptManager ID="scriptManger1" runat="server">

</asp:ScriptManager>
<asp:UpdatePanel ID="updKpf" runat="server">
<ContentTemplate>
<%-- add controls here which you want not to post back during updation--%>
</ContentTemplate>
</asp:UpdatePanel>
