Introduction In the ecosystem of enterprise reporting, few tools have demonstrated the longevity and utility of the Microsoft Report Viewer . For nearly two decades, this control has served as the backbone for rendering paginated reports within Windows Forms, ASP.NET Web Forms, and even modern WPF applications. Despite the tech industry’s pivot toward cloud-based analytics (Power BI, Tableau), the Report Viewer remains an indispensable asset for organizations that rely on SQL Server Reporting Services (SSRS). Open the RDLC file
The strategic direction is (which uses the same RDL schema as SSRS 2016) and the Power BI Embedded platform. The modern Microsoft.ReportingServices.ReportViewerControl NuGet packages exist primarily to support the "lift and shift" of legacy applications to newer .NET runtimes, not to foster new development. Conclusion The Microsoft Report Viewer is a powerful, battle-tested tool that will continue to run corporate reporting for the foreseeable future. By understanding its versioning quirks, mastering the difference between Local and Remote modes, and learning how to render reports to PDF for modern web applications, you can maximize its utility while planning a gradual migration to cloud-native solutions.
// 4. Add the data source ReportDataSource rds = new ReportDataSource("SalesData", dt); reportViewer1.LocalReport.DataSources.Clear(); reportViewer1.LocalReport.DataSources.Add(rds); Set the DataSource to MyDataSet and the available
// 6. Refresh the report reportViewer1.RefreshReport(); Since there is no native .NET Core report viewer, you must use the WebForms control inside an ASP.NET Core project with the Microsoft.AspNetCore.SystemWebAdapters . This is an advanced scenario; for simpler web needs, consider rendering reports to PDF on the server and sending the PDF to the client.
