水晶报表--动态添加子报表

1，创建DataSet

2，将字段绑定(拖动)到子报表

3，将子报表加入到主报表中(省略了主报表部分的初始化)

            //create the relation of main report and the child report

            //Section define the character of this Section.
            // it contains type, name, width, height and so on.

            //visit child reports and databind

            ////visit child reports and databind
            _rptContainerDoc.Subreports[1].SetDataSource(dsSingle);
