What is the TX Text Control Document Viewer?

The Document Viewer is an embeddable browser-based component for viewing, filling, annotating, and signing business documents such as Word and PDF files.

When should I use the Document Viewer?

Use it when users need to access documents inside a web application without downloading files or installing desktop software. It is suited to portals, document management, contracts, forms, and approval workflows.

Which document formats can users view?

The viewer supports Word-compatible documents including DOCX, DOC, RTF, and TX, as well as PDF and PDF/A documents.

Does the viewer support conditional form logic?

Yes. Conditional instructions allow form fields to depend on one another, helping applications create guided workflows for complex documents.

Can users annotate documents?

Yes. Users can add stamps, notes, drawings, comments, and text. Annotations can be stored and synchronized separately from the original document as JSON.

Can documents be signed in the viewer?

Yes. The viewer can be integrated into electronic signature workflows so users can complete, sign, and review documents inside the application.

Does the viewer work on mobile devices?

Yes. The responsive viewer supports document access, form filling, annotations, and signature pad workflows on desktop, tablet, and mobile browsers.

Can I keep signing data on-premises?

Yes. The viewer and related document workflows can be deployed as part of applications running on infrastructure you control, including Windows, Linux, Docker, and cloud environments.

Can I customize the viewer interface?

Yes. Applications can integrate viewer commands, document workflows, annotations, form processing, and signing into their own user interfaces and business logic.

Does the viewer require Microsoft Office?

No. TX Text Control uses its own document engine and does not require Microsoft Word or Microsoft Office automation on the server or client.

Can annotations be saved separately?

Yes. Annotation data can be stored, shared, and synchronized separately from the source document, making it suitable for collaborative review workflows.
