C#关键代码
代码 private void BindReportViewer()
{
BusinessLogic.MetalStatViewCollection MSVCOLL = new BusinessLogic.MetalStatViewCollection();
MSVCOLL = BusinessLogic.MetalStatViewCollection.getMetalStatViewCollection("year=2009 and month=12 and day=3");
IList<rMSV> MSVList = new List<rMSV>();
foreach (MetalStatView m in MSVCOLL)
{
MSVList.Add(new rMSV(m.GroupField, m.clientName, m.weight, m.amount));
}
ReportDataSource rds = new ReportDataSource("DataSet_Metal_DataTableMetal", MSVList);
ReportViewer1.LocalReport.DataSources.Clear();
ReportViewer1.LocalReport.DataSources.Add(rds);
ReportViewer1.LocalReport.Refresh();
}
{
BusinessLogic.MetalStatViewCollection MSVCOLL = new BusinessLogic.MetalStatViewCollection();
MSVCOLL = BusinessLogic.MetalStatViewCollection.getMetalStatViewCollection("year=2009 and month=12 and day=3");
IList<rMSV> MSVList = new List<rMSV>();
foreach (MetalStatView m in MSVCOLL)
{
MSVList.Add(new rMSV(m.GroupField, m.clientName, m.weight, m.amount));
}
ReportDataSource rds = new ReportDataSource("DataSet_Metal_DataTableMetal", MSVList);
ReportViewer1.LocalReport.DataSources.Clear();
ReportViewer1.LocalReport.DataSources.Add(rds);
ReportViewer1.LocalReport.Refresh();
}
需要用dataset的XSD文件作为中转。
详细过程，可以参考：http://www.codeproject.com/kb/aspnet/ReportViewer.aspx
以前按照MSDN的指导，有成功使用过动态绑定RDLC，可这次使用到业务对象，并用ObjectDataSource来作为数据源的中转，结果搞了几天，也总是有问题。
后来，重头来过，不用ObjectDataSource，按codeproject上的简单例子，实现了动态绑定，再将我们要使用的业务对象加上去，通过XSD来中转，一样完成了目标功能。
