Core Capabilities

Everything a modern report viewer should do

Every Bold Reports viewer shares the same JavaScript foundation, so the experience stays consistent whether it's embedded in a React or Angular SPA or a .NET application.

Runtime experience

What your end users touch

Opens a finished report, applies parameters, drills into detail, and exports the result, the runtime experience inside your application.

Flexible hosting

Works with or without a report server

View RDL and RDLC reports with or without connecting to Microsoft SSRS or Bold Report Server, including reports stored locally or embedded directly in your application.

Embedded Tools Setup · Developer & .NET

Native Viewer Component

Each framework gets a purpose-built viewer component with the same toolbar, parameters, and export behavior underneath, so setup takes minutes.

  • Renders RDL/RDLC reports with a native component per framework.
  • Same toolbar, parameters, and export options across every platform.
  • Set the report path, service URL, and auth token, with no extra plumbing.
  • Ready in a few lines of code, not a separate deployment.

Core Capabilities

Everything a modern report viewer should do

Every Bold Reports viewer shares the same capabilities, so the experience stays consistent whether it's embedded in a React SPA or an ASP.NET MVC app.

Connect to any data source

Built-in support for Microsoft SQL Server, SQL Azure, SQL CE, XML, Microsoft Access, Oracle, OLEDB, and ODBC, plus custom data processing extensions for MySQL, SQLite, PostgreSQL, MongoDB, and more.

SQL Server
PostgreSQL
MongoDB
MySQL
ODBC / OLEDB

Rich data visualization

Tables, matrices (pivot tables), lists, charts, sparklines, data bars, gauges, indicators, maps, barcodes, QR codes, and e-signatures, the same visual vocabulary available in the report designer, rendered faithfully at view time.

Charts
Data bars
Pivot tables
Maps
Gauges
Barcodes

Interactive reports

Drill-down, drill-through, hyperlinks, bookmarks, document maps, subreports, and nested data regions let end users explore report detail without leaving the viewer.

Drill-down
Drill-through
Bookmarks
Subreports
Document Map

Report parameters & data shaping

Cascading, query-based, static, and multi-value parameters put report data in end users' control at runtime. Combine with sorting, filtering, grouping, summaries, and calculated fields to reshape the view without touching the underlying report.

Cascading
Query-based
Static
Multi-value
Sorting & grouping

Print & export, pixel-perfect

Export straight from the toolbar to PDF, Word, Excel, PowerPoint, CSV, XML, and HTML, with layout, fonts, and formatting preserved exactly across every format.

PDF
Word
Excel
PowerPoint
CSV / XML / HTML
SQL Server

Themes, responsive rendering & developer APIs

Material, Bootstrap, Fabric, and a high-contrast accessibility theme ship out of the box. Because reports are paginated to a fixed paper layout, they render identically on every device — on smaller screens you scroll to navigate the page rather than the layout reflowing — and the viewer exposes full programmatic control over the toolbar, parameter panel, pages, and dialogs.

Frequently Asked Questions

A report viewer is a UI component that renders reports inside a web or desktop app — so instead of building report rendering, export, and print handling yourself, you embed a ready-made component and let users view, filter, print, and export directly in your application. Formats range from proprietary ones like Crystal's .rpt to open standards, the most popular being RDL (popularized by SSRS) and its .NET counterpart RDLC.

A report designer is a design-time tool for building and editing report layouts — arranging data regions, formatting, parameters, and expressions. A report viewer is the runtime component users interact with to open, explore, filter, and export a finished report. In short: the designer creates reports, the viewer displays them.

Bold Reports ships report viewer components for Angular, React, JavaScript, ASP.NET Core, ASP.NET MVC, ASP.NET Web Forms, Blazor, WPF, and UWP — each with its own integration package and full documentation.

The viewer renders native RDL and RDLC definitions, so most existing SSRS reports upload and run as-is — you reconnect the data source and they render. Reports relying on custom extensions or SSRS-server-specific features are identified up front during migration.

PDF, Word, Excel, PowerPoint, CSV, XML, and HTML, with pixel-perfect formatting preserved across every format.

Yes, Bold Reports is free to try for 30 days, no credit card required.

Crystal Reports .rpt files use SAP's proprietary format, so they're converted to RDL before rendering. Bold Reports provides a Crystal-to-RDL conversion tool that automates this — it processes your .rpt reports and generates RDL equivalents, carrying across layout and formatting so you're not rebuilding by hand.

Yes. You can show, hide, rearrange, or add custom toolbar items, and apply a Material, Bootstrap, Fabric, or high-contrast theme — or override the CSS to match your application's branding. See Toolbar customization and Theming in the docs for the full API.

The viewer renders on demand, page by page — only the requested page is processed and streamed rather than the whole report at once, so load time stays roughly flat as report size grows. For example, a 5,000-row financial statement that paginates into 200 pages loads the first page in about the same time as a 10-page report, because the viewer isn't rendering all 200 pages up front. See On-demand paging in the docs for configuration details.

Yes. Row-level security and role-based access control are built-in — access rules bind to roles or group membership, so one report definition serves everyone while each user sees only their authorized rows. Because the viewer also renders whatever dataset it's passed, you can enforce additional filtering in your own data layer before rendering.
