XML

[WebMethod]

public static List<string> GetAutoCompleteData(string username)
{
List<string> result = new List<string>();
using (SqlConnection con = new SqlConnection("Data Source=SureshDasari;Integrated Security=true;Initial Catalog=MySampleDB"))
{
using (SqlCommand cmd = new SqlCommand("select DISTINCT UserName from UserInformation where UserName LIKE '%'+@SearchText+'%'", con))
{
con.Open();
cmd.Parameters.AddWithValue("@SearchText", username);
SqlDataReader dr = cmd.ExecuteReader();
while (dr.Read())
{
result.Add(dr["UserName"].ToString());
