How to generate an RDLC file using C# during runtime

问题

I'm doing some application development (CRM solution) which require generating diagrammatically an RDLC file at runtime. How do I do that?

回答1:

You can use 'Generate RDLC dynamically - Table' example from got reportviewer? page

Thanks for the response from all who answered this question, but I found one good article to generate dynamic reports: Dynamic Reports with Reporting Services.

Can I confirm that you are trying to build a dynamic reporting solution based on RDLC, or do you just need to mine the data stored in the CRM and show it in a RDLC. I guess you've exhausted other tools such as Proclarity and Excel for users to mine data.

Assuming the former (i.e. an RDLC designer), then RDLC is just an XML file, so I guess you could create simple, standard RDLC's containing datasources, field definitions, cells etc by applying an XSLT after first exporting some kind of xml 'model' from your designer?

Sounds like a lot of work ;)

ALL you have to do is change the the data source by coding. like

        ReportViewer.LocalReport.DataSources.Clear();
        ReportViewer.ProcessingMode = Microsoft.Reporting.WinForms.ProcessingMode.Local;


        ReportDataSource RDS = new ReportDataSource();
        RDS.Name = "DataSet";


        RDS.Value = itemReportTableBindingSource;
        ReportViewer.LocalReport.ReportEmbeddedResource = "RFID.Reports.ItemsReport.rdlc";
        ReportViewer.LocalReport.DataSources.Add(RDS);

        this.itemReportTableTableAdapter.Fill(this.reportsDataSet.ItemReportTable);
        this.ReportViewer.RefreshReport();
