I am trying to get the selected value of the check-box but it is always showing zero in the back-end table even when i select the check-box. The data type for the check-box is bit. I am not sure what am i doing wrong here.
 using (SqlConnection con = new SqlConnection(strConnString))
                using (SqlCommand cmd = new SqlCommand(@"insert into myTable(UserID, Name) values( @UserID, @Name)"))                                                                                            

                    using (SqlDataAdapter sda = new SqlDataAdapter())
                        cmd.CommandType = CommandType.Text;
                        cmd.Parameters.AddWithValue("@UserID", tempUser.ToString());

                        cmd.Parameters.AddWithValue("@Name", chckNM.Checked);

                        cmd.Connection = con;
