推荐答案

您可以尝试以下操作

在加载主报表时创建事件处理程序

You can try this

create eventhandler at the time of main report loading

ReportViewer1.LocalReport.SubreportProcessing += new SubreportProcessingEventHandler(LocalReport_SubreportProcessing);

然后

then

void LocalReport_SubreportProcessing(object sender, SubreportProcessingEventArgs e)
    {
        String param= e.Parameters[0].Values[0];

        ReportDataSource datasource = new ReportDataSource("subrptdatasourcename",subrptdatasource);
        e.DataSources.Add(datasource);
    }
