What if your Blazor app could drop in a full spreadsheet, formulas, tables, charts and all, in just a few lines of markup? That's just one of the things that's new in Radzen Blazor Components v11. Let's get into it.
If you're new here: Radzen Blazor is a free, open-source library of over 145 native Blazor components. And v11 is our biggest release ever, so let's walk through the headline features.
Let's start with the big one: a brand-new RadzenSpreadsheet component, and it's genuinely Excel-class.
It ships with over a hundred Excel-compatible formulas, like VLOOKUP, XLOOKUP, and SUMIFS, with live recalculation as your data changes. You get real tables: sort, filter (including Top 10 and color filters), and a totals row. You can insert charts and images right inside the sheet. There's full undo and redo on everything, CSV and high-fidelity XLSX import and export, and a ribbon you can completely customize and lock down with permissions.
Multiple worksheets, freeze panes, merged cells, data validation, and conditional formatting are all built in too.
Charts got a major upgrade, with more than 30 new chart types, all free and MIT-licensed.
There's a full lineup for finance, like candlestick, OHLC, and high-low. Statistical charts like box plot, histogram, heatmap, and contour. Business charts like waterfall, funnel, and pyramid, plus treemap, radar, pareto, and more.
And across all of them you get render animations, gradient fills, zoom and pan, a crosshair, synchronized charts, a range navigator, and logarithmic and multiple axes. We also redesigned the data labels to stay readable over any fill, and added rounded and exploded pie slices and semi-circle charts.
There are new components, too.
RadzenSignaturePad captures handwritten signatures right in your app, perfect for approvals, agreements, and delivery confirmations.
RadzenTileLayout lets you build dashboards with draggable, resizable tiles, so your users can arrange their workspace exactly the way they like it.
Two components your users rely on every day got significant updates.
The HTML Editor now supports full table creation and editing, so authors can build and adjust tables directly in the rich text editor.
The Scheduler adds a new Agenda view, a clean list-style layout that complements the existing day, week, and month views.
On theming, there's a new premium theme, Material 3 Expressive, available in light, dark, and accessible WCAG variants. See it alongside the rest of our themes on the themes page.
Internationalization is now built in. Localization is resource-based across every component, with more languages shipping out of the box, including German, French, Spanish, Italian, and Japanese, so your app can speak your users' language with zero extra setup.
On top of all that, there's a ton of polish across the whole library, from unified input sizing for the entire input family (via the new InputSize option) to refinements in components like ColorPicker and SelectBar, a ToggleVariant for RadzenToggleButton, and added support for Content Security Policy and trimming.
Before you upgrade, note these breaking changes:

That's Radzen Blazor Components v11: free, open source, and MIT-licensed.
