Ajax autocomplete extender ve table dan veri gösterme ?

Question

Merhaba

Aşağıdaki kodları nasıl birleştirebilirim. Ajax eklediğim textbox sadece aşağıdaki örnekteki string veriyi gösteriyor. Fakat ben table dan veri çekerek göstermek isityorum. Ne yapmam gerekiyor ?

System.Web.Services.WebMethodAttribute(), System.Web.Script.Services.ScriptMethodAttribute()] 
    public static string[] GetCompletionList2(string prefixText, int count, string contextKey) 
    { 
        // Create array of movies 
        string[] movies = { "Star Wars", "Star Trek", "Star Trek", "Star Trek", "Star Trek", "Star Trek", "Star Trek", "Star Trek", "Star Trek", "Star Trek", "Star Trek", "Star Trek", "Superman", "Memento", "Shrek", "Shrek II" }; 
 
        // Return matching movies 
        return (from m in movies where m.StartsWith(prefixText, StringComparison.CurrentCultureIgnoreCase) select m).Take(count).ToArray(); 
    } 
void records() 
{ 
 SqlConnection cn = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ToString()); 
        if (cn.State != System.Data.ConnectionState.Open) 
        { 
            cn.Open(); 
        } 
        SqlCommand cmd = new SqlCommand("kayitcek", cn); 
        cmd.CommandType = CommandType.StoredProcedure; 
                SqlParameter id113 = cmd.Parameters.Add("@txt", SqlDbType.VarChar, 100); 
        id113.Direction = ParameterDirection.Input; 
        id113.Value = txtMovie.Text; 
        SqlDataAdapter da = new SqlDataAdapter(cmd); 
        DataTable dt = new DataTable(); 
        da.Fill(dt); 
cn.Close(); 
}
