         * The 'id' parameter identifies the record.
         */
        return id;
    }
    else {
        /* 
         * You should add a new record to the database here and
         * return its unique identifier (ID).
         */
        int newEmployeeId = 0;
        return newEmployeeId;
    }
}

Delete Record from Database

Implement the EmployeesMasterDetailSimple.DataLayer.DeleteEmployeeFromDataBase method to delete employee information from the database.

• C#

    string q = $"Do you really want to delete {employee.FullName}?";
    if(XtraMessageBox.Show(q, "Employee Deletion", MessageBoxButtons.YesNo) != DialogResult.Yes)
        return false;
