RichTextBox is a professional WYSIWYG editor Tag Helper for ASP.NET Core that delivers a complete content-authoring experience out of the box. With a single tag, you get rich-text formatting, tables, image management, templates, and more — ready for production forms, CMS pages, and email composers.
Full rich-text editing with headings, inline formatting, lists, tables, links, and embedded media.
Browse server folders, drag-and-drop upload, resize inline, and insert images from the built-in gallery.
Insert professionally designed starter blocks — invoices, newsletters, layouts — with one click.
Right-click any table, image, or link for quick contextual actions like merge, split, and edit.
Automatically persist drafts to local storage so users never lose work, even after a page refresh.
Ship with the default or Office 2007 Blue skin, or customize the look to match your application brand.
The editor below is loaded with the full toolbar and realistic sample content. Edit the text, insert images, modify the table, or switch to source-code view to inspect the HTML.
This demo uses the full toolbar preset, which includes every built-in button.
For most projects you will want the default toolbar or a
custom configuration. Explore the Toolbar demos in the sidebar to see all available presets and learn how to build your own.
