从数据库创建特殊的动态数据网格

Question

我正在为我们的univercity（智能半或半自动等）写一个时间表程序。

我正在写这个惠特C＃和访问数据库。

我有下面表的数据库： 1-教师（teacher_id，TEACHER_NAME） 2-类（类标识码，CLASS_NAME） 3-教训（lesson_id，lesson_name） 4-术语（term_id，term_name） 5 - 小时（hour_id，hour_name） 6天（day_id，DAY_NAME） 7-时间表（time_table_id，teacher_id，lesson_id，term_id，class_id_hour_id，day_id）

我写界面污物代码的所有表排除时间表

我认为这个行为最好的事情是datagrid

现在时间表格形式我要像下面

www.uplooder.net/img/image/47/16197657f8466c5a1b8716aee14d768b/csharp.jpg

我想在列标题用户友好的用户界面（排除列右上）显示小时

而行（不包括右上）显示类

而且在任何类和小时组老师的交集和教训

注：

数据网格的

1，第一行是小时，从数据库获取数据网格的 2，第一列（从右到左）是从DB 获得类3，如果先前设定的任何细胞秀老师的名字和课程名称

我该怎么办？

请帮我

非常感谢
