Good day,,

I am having problem with the autocompleteextender in my application. i already created a webservice..

<asp:TextBox ID="txtSKU" runat="server"></asp:TextBox>

            <cc1:AutoCompleteExtender ID="aceSKU" runat="server"
                Enabled="True" 
                ServicePath="http://localhost:3099/WebService1.asmx" 
                ServiceMethod="GetMaterialName"
                TargetControlID="txtSKU" 
                MinimumPrefixLength="2"
                CompletionInterval="100"
                EnableCaching="true"
                ShowOnlyCurrentWordInCompletionListItem="true"    
                 >

    public class WebService1 : System.Web.Services.WebService
    {


        public WebService1()
        {
        }

        [WebMethod]
        [System.Web.Script.Services.ScriptMethod()]

        public DataTable GetMaterialName(string prefixText, int count)
        {
           SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["myConn"].ConnectionString);
           con.Open();
            DataSet ds = new DataSet();
           try
           {
               SqlCommand cmd = new SqlCommand("SELECT description FROM PHSROD20.C1DB.DBO.LKPMATERIAL where description like '%" + prefixText + "%'", con);

               SqlDataAdapter da = new SqlDataAdapter();
               da.SelectCommand = cmd;
               da.Fill(ds);
           }
           catch (Exception err)
           {

               string error = err.ToString();
           }
           //SqlCommand cmd = new SqlCommand();

           finally
           {
               con.Close();
           }

          return ds.Tables[0];

        }
    }
}
<asp:TextBox ID="txtSKU" runat="server"></asp:TextBox>

            <cc1:AutoCompleteExtender ID="aceSKU" runat="server"
                Enabled="True" 
                ServicePath="http://localhost:3099/WebService1.asmx" 
                ServiceMethod="GetMaterialName"
                TargetControlID="txtSKU" 
                MinimumPrefixLength="2"
                CompletionInterval="100"
                EnableCaching="true"
                ShowOnlyCurrentWordInCompletionListItem="true"    
                 >
            </cc1:AutoCompleteExtender>
