Historically, the Report Viewer was bundled directly with Visual Studio and the .NET Framework (System.Web and System.Windows.Forms namespaces).
using Microsoft.Reporting.WinForms;private void LoadReport() // 1. Create and fill data source var dt = new DataTable(); dt.Columns.Add("ProductName"); dt.Columns.Add("UnitPrice"); dt.Rows.Add("Laptop", 1200); dt.Rows.Add("Mouse", 25); microsoft report viewer
// 2. Set up Report Viewer reportViewer1.ProcessingMode = ProcessingMode.Local; reportViewer1.LocalReport.ReportPath = @"Reports\ProductReport.rdlc"; // 3. Add data source matching name in .rdlc ReportDataSource rds = new ReportDataSource("ProductDataSet", dt); reportViewer1.LocalReport.DataSources.Clear(); reportViewer1.LocalReport.DataSources.Add(rds); // 4. Render reportViewer1.RefreshReport();
To understand the Report Viewer, one must first understand its relationship with SSRS. SQL Server Reporting Services (introduced in SQL Server 2000) allowed centralized report management. However, Microsoft soon recognized the need for a control that could render the same RDL files without a server.
Key Milestones:
Today, the control remains a critical tool for legacy maintenance and new internal business apps where simplicity outweighs cloud reporting.
