                <asp:TextBox ID="txtUser" runat="server"></asp:TextBox>  
            </div>

    using System.Linq;  
    using System.Web;  
    using System.Web.UI;  
    using System.Web.UI.WebControls;  
    using System.Data;  
    using System.Data.SqlClient;  
      
    public partial class GetCode : System.Web.UI.Page  
    {  
        protected void Page_Load(object sender, EventArgs e)  
        {  
            if (Request.QueryString["q"] != null)  
            {  
                string key = Request.Params["q"].ToString();  
                string result = "";  
                SqlHelp sql = new SqlHelp();  
                string str = "select top 15 CustomCode from tCustomList where CustomCode like '" + key + "%'";  
                SqlDataReader dr = sql.ExecuteReader(str);  
                while (dr.Read())  
                {  
                    result += dr["CustomCode"].ToString() + "
";  
                }  
                dr.Dispose();  
                sql.SqlClose();  
                if (result == "")  
                    result = "not exists";  
                Response.Write(result);  
            }   
        }  
    }
