    Control properties

    Configure native presentation, document binding, resource policy and replaceable services through AvaloniaHtmlEditor properties. Document content and native chrome have separate settings.

    Use standard Avalonia bindings for the bindable HTML properties and awaited exports when saving the latest edited document.

    Use it in your application

    Set a commercial LicenseKey before constructing any editor. Show the owner window before awaiting Ready.

    BodyHtml is a fragment and DocumentHtml is a full document. Content is the authoring facade; the inherited Child property owns the native visual tree.

    FontFamily and FontSize style native chrome. DefaultFontFamily, DefaultFontSizeInPt and document styling APIs control authored text.

    editor.IsReadOnly = false;
editor.DefaultFontFamily = "Arial";
editor.DefaultFontSizeInPt = 11;
string html = await editor.GetDocumentHtmlAsync();

    Members

    These signatures come from the delivered 1.0.2 assemblies and XML documentation. Cancellation tokens can be supplied to awaited operations. Follow the source-specific notes above when adapting a WPF integration.
