Hi seriverma,

I have created sample that full-fill your requirement. For this sample i have used Northwind database. In order to download the database you will need to visit the following URL.

Install Microsoft Northwind and Pubs Sample databases in SQL Server Management Studio

HTML

<center>
    <b>Categories:</b>&nbsp;
    <table id="tblRadioLists">
    </table>
    <br />
    <b>Selected Value:</b>&nbsp;<span id="lblCategory"></span>
</center>
<div>
    <script type="text/javascript">
        $(function () {
            $.ajax({
                type: "POST",
                url: "Default.aspx/GetCategories",
                data: '{}',
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                success: function (r) {
                    var table = $("[id*=tblRadioLists]");
                    $.each(r.d, function () {
                        var rdb = "<tr><td><input id=rb" + this['Text'] + " onclick=CheckedCategory(this) type='radio' name='rbCategories' value=" + this['Text'] + " /><label for=lbl" + this['Text'] + ">" + this['Text'] + "</label></td></tr>";
                        table.append(rdb);
                    });
                }
            });
        });

        function CheckedCategory(checkedRadio) {
            $('[id*=lblCategory]').text(checkedRadio.value);
        }
    </script>
</div>

Code

[WebMethod]
public static List<ListItem> GetCategories()
{
    string query = "SELECT CategoryID, CategoryName FROM Categories";
    string constr = ConfigurationManager.ConnectionStrings["conStr"].ConnectionString;
    using (SqlConnection con = new SqlConnection(constr))
    {
        using (SqlCommand cmd = new SqlCommand(query))
        {
            List<ListItem> Categories = new List<ListItem>();
            cmd.CommandType = CommandType.Text;
            cmd.Connection = con;
            con.Open();
            using (SqlDataReader sdr = cmd.ExecuteReader())
            {
                while (sdr.Read())
                {
                    Categories.Add(new ListItem
                    {
                        Value = sdr["CategoryID"].ToString(),
                        Text = sdr["CategoryName"].ToString()
                    });
                }
            }
            con.Close();
            return Categories;
        }
    }
}
