Microsoft: Report Viewer

However, for greenfield projects or cross-platform needs, developers should evaluate modern alternatives that offer better performance, maintainability, and cloud-readiness. If you are locked into the Microsoft stack and require SSRS compatibility but cannot use the Report Viewer, consider embedding reports via or using Power BI Report Server (on-premises paginated reports).

// Create a new report viewer ReportViewer reportViewer = new ReportViewer();

For legacy desktop applications running on .NET Framework 4.6+, the official package is . WebForms (.NET Framework)

For new development, Microsoft recommends: microsoft report viewer

Install-Package Microsoft.ReportingServices.ReportViewerControl.WebForms Use code with caution. Step 2: Install the RDLC Report Designer Extension

In enterprise application development, the ability to generate pixel-perfect documents—invoices, receipts, operational dashboards, and operational lists—is a fundamental requirement. Microsoft Report Viewer has historically served as the primary rendering engine for these documents within .NET desktop and web applications.

In this mode, the application itself performs all the report processing. The developer creates a Report Definition Language Client-side (.rdlc) file. The data is typically supplied as a collection of objects (like a List or DataTable) from the application's memory. WebForms (

Offers comprehensive desktop and web report designers with high-performance rendering engines.

Step-by-Step: Implementing Local Reports (.rdlc) in a WinForms Application

Does not require a SQL Server Reporting Services license or server instance; ideal for offline or standalone desktop apps. In this mode, the application itself performs all

: These XML-based schemas describe the report's format, including data field definitions, report parameters, and visual elements like tables, charts, and headers. Multi-Platform Support : The control supports various UI technologies, including ASP.NET Core ASP.NET MVC Interactivity

Integrated via ASP.NET Core API backends and JavaScript/Blazor frontends. Remote vs. Local Processing Modes

The Report Viewer can be a vector for attacks and Remote Code Execution (RCE) if not configured correctly.

The Report Viewer does not query databases directly in Local Mode. Developers must implement a "Push" model.
