rdlc报表 矩阵控件下的按组分页

场景：

使用rdlc开发报表，例如订单产品报表，显示多个订单，一个订单有动态生成的固定的多个产品组成，同时统计每个订单里多个产品数量总数。

数据库层面分析：

此报表属于交叉报表，例如5个订单，3个产品，总共的数据库记录应该为15条，而不是5条。

 

存在的技术难点：

（1）动态列生成

使用Matrix矩阵控件

（2）统计每个订单里多个产品数量总数

确保每个订单的第一条数据是正确的，第二条或第三条数据为NULL都没关系

（3）控制每页显示33条记录，而不是通过默认的高度来控制分页

（4）由于是使用矩阵控件，所以分页下序列号需从数据库中控制好

 

最终完成的效果：

 

（1）数据库方面：
