I am using Server Side code to do Paging on SharePoint List. I am using Visual Web Part to show items from List.

protected void Page_Load(object sender, EventArgs e)

   if (!this.Page.IsPostBack)
       // below function loads data from sharepoint list. Not showing whole logic as its not required

When I load data it loads whole Page. Is it possible to load only that Web Part instead of whole Page. Any examples?


I tried to use Ajax update panel in ascx file

<asp:updatepanel runat= "server>
<section id="ideas" class="container">
            <a href="#" role="button" id="btnShow"  runat="server" OnServerClick="btnShow_Click">Get data</a>


But in my code behind i cannot get divTest and it throws compile time error. Whats wrong in this?

  • asp:panel is not UpdatePanel. Second to access control from server side you need to mark runat="server" Jun 5, 2015 at 22:14
  • @AmalHashim you see i have marked them already

There are a few issues with your code.

First off, you have not declared the UpdatePanel correctly. You are missing the closing double-quote on the runat attribute and you are missing the ContentTemplate element. This is an example of a correctly declared UpdatePanel from this article on MSDN:

    <asp:UpdatePanel ID="UpdatePanel1" runat="server">
            <asp:Calendar ID="Calendar1" runat="server"></asp:Calendar>

Second, even if you declared the UpdatePanel correctly it would have no effect. The UpdatePanel works with Server Controls, not raw HTML elements.


You need to use Ajax to do this.

In ASP.Net for implementing this in Server Side we use UpdatePanel. For more you can check asp.net community site https://ajaxcontroltoolkit.codeplex.com/documentation

You can also use client side for implementing the same. In client side you either JavaScript object model or REST API to query data and load it to table etc using jQuery.
