Question

我试图在水晶报表中输入与其编辑掩码不匹配的参数值。它会引发Report Application服务器失败错误。无论如何都要捕获此异常并抛出用户可理解的异常。问题是堆栈跟踪没有显示我的代码的任何部分。通过我的代码写入.net的方式

System.Runtime.InteropServices.COMException: The Report Application Server failed

Answer 1

Asp.net ReportViewer有ReportError个事件，您可以处理并自定义错误OnReportError="ReportViewer1_OnReportError"

检查CrystalReportViewer是否有类似内容：

CrystalReportViewer.onHandleException or
CrystalReportViewer.OnHandleExceptionAndPromptIfNeeded

HandleException()   Fired when an exception occurs.

参考：http://www.crystalreportsbook.com/Crystal_Reports_Net_Ch14_3.asp 不容易找到新的文件。
