HTML

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <script src="Scripts/jquery-1.4.1.js" type="text/javascript"></script>
    <script language ="javascript" >
        function postrowtodel(id) {
            $.get("default12.aspx?action=delete", { name: id }, function (data) {
                location.reload();
            });
        }
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:datalist id="DataList1" runat="server" xmlns:asp="#unknown">
          <HeaderTemplate >
         <table width="100%"><tr><td>first col</td><td>second col</td></tr>
        </HeaderTemplate>
        <itemtemplate>
          <table><tbody><tr><td><a href="javascript:postrowtodel('<%# Container.DataItem %>')">Delete</a></td><td><![CDATA[<%# Container.DataItem %>]]></td></tr></tbody></table>
        </itemtemplate>

    </div>
    </form>
</body>
</html>

and code behind file contains following code

C#

//under PageLoad method
 if (!IsPostBack)
        {
            List<string> list; 
            if (Request.QueryString["action"] != null)
            {
                if (Request.QueryString["action"].ToString() == "delete")
                {
                    Response.Clear();
                    list = (List<string>)Session["DataSource"];
                    list.Remove(Request.QueryString["name"].ToString());
                    Response.Write("");
                    Response.End();
                }
            }
            else
            {
                if (Session["DataSource"] != null)
                {
                    list = (List<string>)Session["DataSource"];
                }
                else
                {

                    list = new List<string>();
                    list.Add("Bread");
                    list.Add("Cheeze");
                    list.Add("Wine");
                    list.Add("Beer");
                    list.Add("Waffles");
                    Session["DataSource"] = list;
                   
                }
                DataList1.DataSource = list;
                DataList1.DataBind();
