RDLC报告有时无法正常工作 [英] RDLC reports not working sometime

问题描述

我在过去的2-3天内遇到了这个问题

之前我的RDLC报告加载得非常快但是现在有时报告正在加载，有时页面刷新图标正在旋转但是RDLC报告没有加载并且没有任何错误消息显示。

解决方案

在添加数据源之前报告清除数据源



< pre lang =cs> ReportViewer1.LocalReport.DataSources.Clear（）;
ReportViewer1.LocalReport.DataSources.Add（rds）;
ReportViewer1.LocalReport.DataSources.Add（rds2）;

I am facing this problem from last 2-3 days
Earlier my RDLC reports were loading very fastly but nowdays sometimes reports are loading and sometimes the page refreshing icon is rotating but RDLC report is not loading and neither any error message is displaying .

解决方案

before adding datasources to report clear your datasource

ReportViewer1.LocalReport.DataSources.Clear();
                ReportViewer1.LocalReport.DataSources.Add(rds);
                ReportViewer1.LocalReport.DataSources.Add(rds2);
