I am able to show just one column 'mem_name'. I want to show an extra column 'mem_id' also. Can anyone help me out. My code:

SqlCommand cmd = new SqlCommand("select * from member where mem_name like @Name+'%'", con);
cmd.Parameters.AddWithValue("@Name", prefixText);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);
List<string> CountryNames = new List<string>();
for (int i = 0; i < dt.Rows.Count; i++)
{
CountryNames.Add(dt.Rows[i][1].ToString());
}
return CountryNames;

Hi S.Rajendran,

1.take code on your .aspx page

XML

<asp:TextBox ID="_txtMem" runat="server" Width="150px" AutoPostBack="true" OnTextChanged="_txtMem_TextChanged"></asp:TextBox>

//add AutoCompleteExtender with atleast these properties//

XML

<asp:AutoCompleteExtender ID="_txtBuy_AutoCompleteExtender" runat="server"
OnClientItemSelected="ClientItemSelectedMem">
</asp:AutoCompleteExtender>

XML

<asp:HiddenField ID="hfMemId" runat="server" />

2.Use javascript

JavaScript

<script type="text/javascript">
        function ClientItemSelectedMem(sender, e) {

            var hdMemID = $get('<%= hfMemId.ClientID %>');

            hdMemID.value = e.get_value();

        }
    </script>

3.place this code on _txtMem_TextChanged Event on .cs page

C#

string MemId = "";
        string MemName = "";
        customerId = Request.Form[hfMemId.UniqueID];
        customerName = Request.Form[_txtMem.UniqueID];

4.use GetCompletionList method like this

C#

// Select member from database//
Member = aBal.SltMem(prefixText);
        if (Member.Count > 0)
        {
            foreach (string i in Member)
            {
                string[] splt = i.Split(',');
                string item = AjaxControlToolkit.AutoCompleteExtender.CreateAutoCompleteItem(splt[1].ToString(), splt[0].ToString());
                list.Add(item);
            }
        }
        else
        {
            list.Add("No Member Named " + prefixText + "");
        }
        return list.ToArray();
<pre>
