Hey guys,

I am currently implementing an autocomplete feature without using a webservice, and have put my ServiceMethod attribute in the autocomplete extender as GetProviders.

Here's how the GetProviders method looks like in the xxx.aspx.cs:

C#

public static string[] GetProviders(string prefixText, int count)
  {
      ArrayList fd = new ArrayList();
      fd.Add(DBManager.GetAllFood());
      return fd;
  }

Any idea how I can improve it??

Thanks in advance

I use auto complete Extender just the way you do.. here take a look on code:

aspx page:

VB

<asp:AutoCompleteExtender ID="TextBox1_AutoCompleteExtender" runat="server"
CompletionInterval="10" CompletionSetCount="10" DelimiterCharacters=""
Enabled="True" FirstRowSelected="true" MinimumPrefixLength="1"
ServiceMethod="GetName" TargetControlID="TextBox1" UseContextKey="true">

aspx.cs code:

[System.Web.Services.WebMethod]
    [System.Web.Script.Services.ScriptMethod]
    public static List<string> GetName(string prefixText, int count)
    {
        if (count == 0) //count should not be zero
        {
            count = 5;
        }
        SqlConnection conn = new SqlConnection();
        conn.ConnectionString = <connectionstring>;
        SqlCommand cmd = new SqlCommand(sqlquery, conn);
        conn.Open();
        List<string> names = new List<string>();
        SqlDataReader dr = cmd.ExecuteReader();
        while (dr.Read())
        {
            names.Add(dr[<columnname>].ToString());
        }
        conn.Close();
        return names;
    }</columnname></connectionstring>

lemme know if it was what you were looking for.
