Can't find what you need? We're here to help.

No. This component is part of the Avalonia Pro and Enterprise tiers. Activation requires an Avalonia account and a valid Pro or Enterprise licence.

Yes. Each component gives you a ready UI out of the box, but you can build a bespoke interface by using the underlying classes directly and wiring up your own commands and visuals.

Supported formats depend on the underlying platform. Check the component's documentation and the platform's own capability lists for specifics.

Avalonia UI components support Windows, macOS, Linux, iOS, Android, and WebAssembly. Each component uses the native platform back-end for optimal performance and compatibility.
