推荐答案

为什么不用清除按钮，在触发器上用空数据集重新绑定水晶报告。这样就可以清除数据了。

Why don''t you put clear button, on trigger of which you re-bind the crystal report with an empty dataset. This would give effect of clearing data.

就这么做..

CrystalReportViewer1.ReportSource = Nothing

CrystalReportViewer1.Refresh（）

它将清除你的水晶报告查看器。

Just do it..
CrystalReportViewer1.ReportSource = Nothing
CrystalReportViewer1.Refresh()
It will clear your crystal report viewer.
