问题：无法绑定Reportviewer中的报告。我得到的纪录“dtnew”，但CNT看到我的申请报告问题与rdlc报告在asp.net

在报告

得到错误“的数据源实例尚未提供数据源‘dsInOutReport_InOut’”

难道问题是您在报告文件（“dsInOutReport_InOut”）中使用的另一个数据源名称比您在代码中指定的名称（“dbInOutTimeDataset_ReportInOut”）？ – DavveK

在此之前

reportViewer1.LocalReport.DataSources.clear();

：添加此

reportViewer1.LocalReport.DataSources.Add(rptds);
