What is it?

Radzen Blazor Components is a UI component library for building web applications with Blazor in C#. It covers data-heavy interfaces with a DataGrid, PivotDataGrid, Scheduler, Gantt chart and an Excel-like Spreadsheet that supports formulas and XLSX import/export. Its charting set includes more than 30 chart types, rendered as SVG in C# without a JavaScript charting library.

The library also includes form controls, layout and navigation components, feedback elements and utilities such as QR codes and barcodes. It ships with several built-in themes, including Material, Standard, Default, Humanistic and Software, each with light and dark variants, plus CSS variable customization and a theme service for runtime switching. Premium themes are offered through a separate paid subscription.

An AI toolkit provides AIChat with tool calling, approvals and attachments, along with AIPrompt and SmartPasteButton.
