# TX Text Control .NET for Windows Forms > A word processing component for Windows Forms: rich text editing, tables, images, mail merge and PDF, with the full document engine behind it. - **Product:** TX Text Control .NET for Windows Forms - **Kind:** Topic - **Path:** TX Text Control .NET for Windows Forms - **1056 words** - **Web URL:** https://docs.textcontrol.com/tx-text-control-dotnet-winforms/ - **LLMs URL:** https://docs.textcontrol.com/tx-text-control-dotnet-winforms/llms.txt - **LLMs-Full URL:** https://docs.textcontrol.com/tx-text-control-dotnet-winforms/llms-full.txt --- TX Text Control .NET for Windows Forms is a word processing component you drop onto a form. It gives your application a complete editor — formatted text, paragraph and character styles, tables, images, headers and footers, footnotes, form fields and merge fields — and it reads and writes the formats your users already work in, including DOCX, DOC, RTF, HTML and PDF. The same document engine is available without a user interface, so the documents your users edit on screen are the documents your code creates, merges and converts. Nothing else has to be installed on the machine: TX Text Control handles the formats itself, with no Microsoft Word and no Adobe Acrobat involved. ### What It Gives Your Application A `TextControl` gives your users a word processor on a form. The ribbon, toolbars, rulers, sidebar and status bar around it drive the editor, `ServerTextControl` processes documents with no user interface at all, and `MailMerge` builds invoices, letters and reports from a template and your data. [What You Can Build](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/overview/introduction/#what-you-can-build) matches these classes to typical tasks. Documents are loaded and saved through one set of stream types, so a file a user opens as DOCX can be saved as PDF, PDF/A, RTF, HTML or plain text without any other component. The dialogs users expect — font, paragraph, tabs, tables, styles, images, hyperlinks, bookmarks, comments and tracked changes among them — are built in and can be opened from your own menus. ### Who This Documentation Is for It is written for .NET developers building Windows desktop applications, and it assumes you know C# or Visual Basic and Windows Forms. It does not assume you know anything about TX Text Control. ### How This Documentation Is Organized - **[Overview](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/overview/llms-full.txt)** explains what the component is, how the editor and the engine relate, and what a document is made of. - **[Installation Guide](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/installation/llms-full.txt)** covers the requirements, the packages and the licensing you need before you write any code. - **[Getting Started](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/getting-started/llms-full.txt)** puts the component on a form and builds a working editor step by step. - **The feature sections**, [Document Editor](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/document-editor/llms-full.txt), [Document Processing](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/document-processing/llms-full.txt), [Mail Merge and Reporting](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/mail-merge/llms-full.txt), [PDF Processing](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/pdf/llms-full.txt) and [Digital Signatures](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/digital-signatures/llms-full.txt), cover each feature in detail, in the editor and in code. - **The application around the editor** is the subject of the [Integration Guide](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/integration/llms-full.txt), with the designer, user controls, databases and menus, and of the [Deployment Guide](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/deployment/llms-full.txt), [Security](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/security/llms-full.txt) and [Performance](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/performance/llms-full.txt). [What's New](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/whats-new/llms-full.txt) lists the changes of each version. - **[API Reference](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/reference/llms-full.txt)** documents every class, property, method and event of the .NET API. ### The .NET API The [.NET API](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/reference/dotnet-api/llms-full.txt) documents every class, property, method and event. Its main namespaces are `TXTextControl` for the editor, the engine and the elements of a document, `TXTextControl.DocumentServer` for mail merge and reporting, and `TXTextControl.Windows.Forms` for the ribbon and the sidebar; the [Introduction](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/overview/introduction/#building-blocks) describes what each one holds. ### Where to Start 1.
