                DataSet userDS = new DataSet();

              
                   conn = new SqlConnection(connectionString);
                   conn.Open();
                   // execute the command
                  // dataReader = new SqlDataReader( conn);

                string connectionString = ConfigurationManager.ConnectionStrings["Dorknozzle"].ConnectionString;
                comm = new SqlCommand("select Username, Password from tblEmployee where Username =" + username + "‘ AND Password =’" + password, conn);

The name 'Username' does not exist in the current context means the field are not available First try to create the instance of usercontrol then try to use it

Try this

TextBox tempTextBox = (TextBox)(Username)
string username.Text = tempTextBox.Text;
