Step 1 : Create a table :
 
create table DbTable (
ID int Primary key identity (1,1),
Name nvarchar(max) Not null,
Manufacturer nvarchar(max),

using System.Web;
using System.Data;
using System.Data.Sql;
using System.Configuration;
using System.Data.SqlClient;
using System.Web.Script.Serialization;
using System.Web.SessionState;

namespace AMS_New_Project.Handler
{
    /// <summary>
    /// Summary description for HW_AssetName
    /// </summary>
    public class HW_AssetName : IHttpHandler
    {

        public void ProcessRequest(HttpContext context)
        {
            string term = context.Request["term"] ?? "";
            List<string> listofassetnames = new List<string>();
            string constr = ConfigurationManager.ConnectionStrings["ConStr"].ConnectionString;
            using (SqlConnection con = new SqlConnection(constr))
            {
 
                con.Open();
                SqlCommand cmd = new SqlCommand("select Name from DbTable where Name like @name + '%' group by Name", con);
                cmd.Parameters.Add(new SqlParameter()
                {
                    ParameterName = "@Name",
                    Value = term,
                });
                SqlDataReader rdr = cmd.ExecuteReader();

                while (rdr.Read())
                {
                    listofassetnames.Add(rdr["Name"].ToString());
                }
                con.Close();

            }
            JavaScriptSerializer jss = new JavaScriptSerializer();
            context.Response.Write(jss.Serialize(listofassetnames));



        }

        public bool IsReusable
        {
            get
            {
                return false;
            }
        }
    }
}
