为主报表的每个子报表触发子报表处理事件。

目前已处理的子报表数据在SubreportProcessingEventArgs中传递。这将为您提供所需的所有信息。

SubreportProcessing event is triggered for every subreport of your main report.
Currently processed subreport data is passed in SubreportProcessingEventArgs. That gives you all informations what you need.

void LocalReport_SubreportProcessing(object sender, Microsoft.Reporting.WinForms.SubreportProcessingEventArgs e)
{
    // Args contains information about currently processed subreport
    //e.ReportPath -> Gives you path for your subreport
    //e.Parameters -> Parameters of your subreport
    //e.DataSourceNames -> List of names of data sources you use in subreport
    //e.DataSources -> Returns datasources in your subreport
}
