钻取报表开发步骤：
先看总体效果：如图
点击单据编号
下面就做个看看...
1.先添加一个RDLC报表文件作为钻取报表.
添加一个RDLC报表,在设计界面添加一个表格Table,配置好数据源如图：
2.设置钻取报表对应的字段.
(1) 也许看到上面orderID为什么和别的不一样，多了个下划线了吧！不急,这里看怎么设置的.
鼠标点击orderID这列，右击文本框属性，找到字体选项卡如图：
在效果里将默认改为下划线。
(2)下面设置钻取报表.
然后再选择操作选项卡，第一步：设置启用为超链接为：转到报表(R).第二步：设置指定报表，指定报表里面填写钻取子报表的报表名如(DrillThoughReport) 不要加.rdlc 后缀名哦.第三步：添加参数,添加参数名和参数的值(值可以是Table 的列值和参数等)
总体设置如图：
点击确认.下一步设置子报表了.
3.设置子报表
转到子报表里，添加子报表的参数,这个参数来自哪里呢？当然是前面主报表里面设置过的参数啊,所以在这里添加参数，参数名orderID(注意参数名的大小写)并选中允许空白值和Null值.然后点击确认.最后在子报表里面添加数据就OK了.(主报表的数据源实际和子报表的数据源是一对多的关系 这里的主外键就是orderID啦)
如图：
好了。设置报表阶段基本完成.下面就代码了。
