如何将数据源绑定到.rdlc报告在c＃ [英] how to bind datasource to a .rdlc report in c#

问题描述

朋友，我已经开发了一个简单的应用程序使用c＃，它有两个rdlc报告

Friends , I have developed a simple application using c# , it has two rdlc reports

我使用下面的代码将数据源绑定到报表查看器

i used this below code to bind datasource to report viewer

 this.reportViewer1.LocalReport.ReportPath = @"C:\Documents and Settings\Administrator\My Documents\Visual Studio 2008\Projects\reports\reports\Report1.rdlc";
 reportViewer1.LocalReport.DataSources.Clear();
 reportViewer1.LocalReport.DataSources.Add(new ReportDataSource("customer", dt.Tables[0])) ;
 this.reportViewer1.RefreshReport();

但是当报告生成时，它是空的报告没有数据会显示，任何意见？

But when the report is generated ,it is empty report no data will displayed , any opinion???

推荐答案

当您通过向导在项目中添加.rdlc报告时，默认情况下将数据集名称设置为'DataSet1' 。现在，如果要动态绑定新数据集，则该数据集的名称必须为'DataSet1'。尝试更改它，并检查表[0]是否包含一些数据（Rows），其中 DataType 与原始dataType DataSet1 匹配。如果DataType不匹配，那么数据不会在ReportViewer中。尝试以下代码： -

When you add .rdlc report in your project by wizard then by default it take dataset name as 'DataSet1' . Now if you want to bind dynamically new dataset then name of that dataset must be 'DataSet1'. Try change it and also check that Table[0] contains some data(Rows) for which DataType get matched with original dataType of DataSet1. If DataType doesn't matches then data wont come in your ReportViewer. Try this code:-

string exeFolder = (Path.GetDirectoryName(Application.StartupPath)).Substring(0, (Path.GetDirectoryName(Application.StartupPath)).Length - 3);
string reportPath = Path.Combine(exeFolder, @"Reports\SessionReport.rdlc");
Microsoft.Reporting.WinForms.ReportDataSource rds = new Microsoft.Reporting.WinForms.ReportDataSource("DataSet1", yourDataSet.Tables[0]);
this.reportViewer1.LocalReport.DataSources.Add(rds);
this.reportViewer1.LocalReport.ReportPath = reportPath;
this.reportViewer1.RefreshReport();
