What is the TX Text Control Document Editor?

The TX Text Control Document Editor is an embeddable browser-based word processor for business applications. It enables users to create, edit, review, and collaborate on Microsoft Word-compatible documents directly inside web applications. The editor integrates seamlessly into ASP.NET Core, Angular, React, Blazor, JavaScript, and other web frameworks while using the same document engine as the TX Text Control server components.

Who is the Document Editor designed for?

The Document Editor is designed for developers building enterprise applications that require professional document editing, including contract management, legal document review, insurance, healthcare, banking, government, CRM, ERP, and document management systems.

Does the editor require Microsoft Word or Microsoft Office?

No. The Document Editor uses the native TX Text Control document engine and does not require Microsoft Word or Microsoft Office on the client or server.

Is the editor truly WYSIWYG?

Yes. The editor provides true page-based WYSIWYG editing with pixel-perfect rendering. Documents appear as printed pages while editing, preserving layout, pagination, headers, footers, tables, images, floating objects, and formatting.

Is the editor compatible with Microsoft Word documents?

Yes. The editor is designed for high-fidelity DOCX editing and supports Microsoft Word-compatible formatting, styles, tables, sections, headers, footers, comments, tracked changes, fields, images, and many other document elements.

Which editing features are supported?

The editor supports rich text formatting, styles, tables, images, text frames, page layout, sections, headers and footers, lists, columns, bookmarks, hyperlinks, form fields, tables of contents, comments, tracked changes, spell checking, and many additional word processing features.

Can users customize the editor interface?

Yes. Developers can customize ribbon tabs, toolbars, dialogs, context menus, commands, keyboard shortcuts, and integrate the editor into their own application workflows using JavaScript and server-side APIs.

Does the editor support Track Changes?

Yes. Track Changes is fully supported. Insertions, deletions, and other revisions are displayed visually and include author and timestamp information. Changes can be accepted or rejected individually or in bulk.

Are comments supported?

Yes. Users can insert, edit, reply to, and review comments directly in the document, making the editor suitable for document review and approval workflows.

Can multiple users collaborate on documents?

Yes. Applications can build collaborative editing and review workflows using the Document Editor together with the WebSocket synchronization architecture. Documents remain synchronized while preserving true WYSIWYG rendering.

How does the Document Editor work?

The current Document Editor uses a WebSocket-based architecture. The browser communicates with a server-side document engine that performs layout calculations and synchronizes the document in real time, providing consistent rendering across all users and platforms.

Why does the editor use WebSockets?

Professional word processing requires continuous document synchronization and layout updates. The WebSocket connection provides low-latency communication between the browser and the server, enabling true WYSIWYG editing instead of simplified HTML editing.

Does the editor work on Linux and in Docker?

Yes. The WebSocket backend can be hosted on Windows or Linux and deployed in Docker containers, Kubernetes, and cloud platforms including Microsoft Azure.

Is a WebAssembly version available?

A native WebAssembly edition is currently in development. Unlike the WebSocket-based editor, the WebAssembly version executes the TX Text Control document and rendering engine directly inside the browser, enabling local document processing, reduced server load, offline editing scenarios, and eliminating WebSocket communication during editing.

Which frameworks are supported?

The Document Editor integrates with ASP.NET Core, ASP.NET, Angular, React, Blazor, JavaScript, and other modern web application frameworks through official NuGet packages, npm packages, and JavaScript APIs.

Can I control the editor using JavaScript?

Yes. A comprehensive JavaScript API provides access to document commands, formatting, events, selections, UI customization, printing, document loading and saving, and application-specific integrations.

Can I restrict what users are allowed to edit?

Yes. Applications can implement protected editing scenarios using editable regions, form fields, content controls, permissions, and application logic to limit which parts of a document users may modify.

Which document formats can the editor open and save?

The editor supports Microsoft Word DOCX, DOC, RTF, HTML, Markdown, TX Text Control documents, and additional formats depending on the selected server components. Documents can also be exported to Adobe PDF.

Can users edit PDF documents?

The Document Editor focuses on Word-compatible document editing. PDF documents can be viewed, annotated, processed, converted, and integrated into document workflows using the TX Text Control document processing components.

Can documents be converted to PDF?

Yes. Documents can be exported as PDF, including PDF/A for long-term archiving and PDF/UA for accessible document workflows.
