推荐答案

您需要获取数据集或数据表中的表，然后在水晶报表中调用它。您不能将datagridview用于水晶报告。

You need the get the table in a dataset or datatable and then call it in crystal report. You cannot use datagridview for crystal report.

CrystalReport3 cr = new CrystalReport3();
          cr.SetDataSource(dt)//Where dt is the datatable object.;

谢谢
