GrapeCity.ActiveReports.Web.ReportService中有几个virtual方法:
protected virtual string GetPhysicalPath(string prefix, string path)
protected virtual object OnCreateReportHandler(string reportPath)
protected virtual void OnLocateCredentialsHandler(object sender, LocateCredentialsEventArgs locateCredentialsEventArgs)
这些方法都是在什么时候用呀?
前两个方法应该返回什么样的值呢? |
