报无法连接数据源，这应该就是你的数据连接哪里存在问题。你在本地看看能不能正常运行，然后我们本地导出还 ...
但是我是动态报表呀 怎么会跟数据连接有关系 。 你不点击导出，就是一个正常展示可以正常的展示不。由于你用的是动态绑定数据源，打印的时候其实也是需要进行一个动态数据源的绑定的，这是我刚刚写的一个打印这块绑定数据源的一个代码示例private void button2_Click(object sender, EventArgs e)
{
string file_name = @"..\..\RdlReport1.rdlx";
GrapeCity.ActiveReports.PageReport pageReport = new GrapeCity.ActiveReports.PageReport(new System.IO.FileInfo(file_name));
pageReport.Document.LocateDataSource += new LocateDataSourceEventHandler(LocateData);
pageReport.Document.Printer.DefaultPageSettings.Margins.Bottom = 0;
pageReport.Document.Printer.DefaultPageSettings.Margins.Left = 0;
pageReport.Document.Printer.DefaultPageSettings.Margins.Right = 0;
pageReport.Document.Printer.DefaultPageSettings.Margins.Top = 0;
pageReport.Document.Printer.PaperSize.RawKind = 0;
pageReport.Document.Printer.PaperSize.Width = 790;
//pageReport.Document.Printer.PaperSize.Height = 20;
GrapeCity.ActiveReports.PrintExtension.Print(pageReport.Document, true, true);//通过设置第二个属性为false实现静默打印。
