RichTextBox supports the latest versions of Chrome, Firefox, Safari, and Microsoft Edge on both desktop and mobile devices.
Yes. Use the toolbar attribute to choose a preset (default, full, basic, ribbon, office) or pass a custom toolbar string with your own button layout. See the Custom Toolbar demo.
The package includes built-in upload endpoints mapped via app.MapRichTextBoxUploads(). Images are uploaded to wwwroot/uploads by default. The gallery dialog supports folder browsing, folder creation, and file upload.
Yes. Use content-css-url for an external stylesheet or content-css-text for inline CSS rules. See the Content CSS demo.
Yes. The paste-mode attribute supports Auto (default), Text, Word, and Disabled modes. The Word mode strips Word-specific markup while preserving essential formatting. See the Paste from Word demo.
Yes. Set auto-save="true" with auto-save-key and auto-save-delay to persist draft content in localStorage. See the Autosave demo.
Yes. Use max-html-length to limit total HTML characters or max-text-length to limit visible text characters.
Yes. The AI Toolkit ships with the package: Ask AI in the toolbar, a docked AI Chat panel, and a persistent AI Review drawer. Turn it on with enable-ai-toolkit="true" on the tag helper. The built-in demo resolver works with no API key, and you can swap in your own backend at any time. See the AI Toolkit demo.
Any provider you want — the AI Toolkit is provider-agnostic and uses a bring-your-own-key (BYOK) pattern. Register an IRichTextBoxAiResolver server-side, or call editor.aiToolkit.setResolver(fn) on the client. Your resolver talks to your own backend (which holds the provider API key) and returns { result, reason, operations }. See the BYOK demo.
Yes. Set enable-structured-content="true" on the tag helper. The editor then exposes editor.getJSON() and editor.setJSON(obj), and window.RichTextEditorStructuredContent provides fromMarkdown(md), toMarkdown(json), renderHTML(json), and validateStructuredContent(json). See the Structured Content demo.
Yes. The ASP.NET Core package intentionally keeps familiar concepts from the Web Forms version. The office2007blue skin with the ribbon toolbar provides a matching visual target. See the Office 2007 Blue demo.
The Core package supports default, full, basic, ribbon, and office toolbar presets. Custom toolbar strings use the same button name syntax. The overall layout is compatible with minor differences in available commands.
