A Windows Forms application with a TextControl on its form is a word processor: users type, format, insert tables and images, review changes and print, while your code loads documents, reacts to events and adds commands of its own. The pages below take each of these subjects further than the first tutorials, from the life of the control on a form to the ribbon, the dialog boxes and the events around it.

If you haven't placed an editor on a form yet, start with the tutorials of Document Editor in Getting Started. They create the project, add the control from the Toolbox, connect a ribbon or a button bar and build the file commands that every page here assumes.

TX Text Control Words, the sample word processor, with its ribbon, the Form Fields tab selected, a horizontal and a vertical ruler, a form with a drop-down list in the document and a status bar.

How the Editor Works

One control holds the document. TextControl is a Windows Forms control that you drag from the Toolbox onto a form. Its document consists of the main text, text frames, headers, footers and footnotes.
Users need no code. Typing, selecting, the clipboard keys, undo and the context menus work as soon as the control has the focus.
Your code shares the object model. Selection and collections such as Tables and Sections also belong to ServerTextControl, which Document Processing uses without a user interface.
The interface around it is made of controls. A Ribbon or a button bar, rulers, a status bar and sidebars are separate controls that you connect to the TextControl through properties, in the designer or in code.
