Answer / deepak ray

Just retrieve the id from database using reader or dataset
and store the id in a string.
and
set the string in a public readonly property like this.


string _UserId;
public string UserId
{ get { return _UserId; } }

SqlDataReader dr = null;
dr = cmd.ExecuteReader();
if (dr.HasRows)
{
dr.Read();
_UserId = dr["UserId"].ToString();
}
dr.Close();
dr.Dispose();
