Even after i click the textbox with different values that are already there in the xml , nothing is auto populated


    [System.Web.Services.WebMethodAttribute(), System.Web.Script.Services.ScriptMethodAttribute()]
    public static string[] GetCompletionList(string prefixText, int count, string contextKey)
    {
        XmlTextReader Reader = new XmlTextReader("App_Data/Employee.xml");

        List<string> returnData = new List<string>();

        while (Reader.Read())
        {

            returnData.Add("//EmployeeName");
        }

        return returnData.ToArray();
        //return default(string[]);
    }

I am not sure if the control is even passed to this function. How can i check it the control is passed to this function
