Check Spelling in More Than 20 Languages

RichTextBox supports two types of spell checking. With a modal dialog, the end user can choose to ignore each misspelled word one by one or add the word to a user dictionary. With as-you-type checking, misspelled words are highlighted with a wavy, red underline. The end user can right-click the word in the document to see a menu with suggestions and other options. We provide 22 international dictionaries free for you to distribute with your application.

Highly Modifiable Document Object Model

Patterned after the Document class in WPF, RichTextBox's rich document object model (DOM) supports images, lists, hyperlinks, borders, background and foreground colors for text ranges, and more. Use the rich DOM to create and modify documents programmatically. For example, you can extend the control to behave as a syntax highlighter.

Import and Export Formats

RichTextBox supports importing and exporting RTF, HTML, and plain text. Load existing rich text or HTML into the RichTextBox control, edit the document, and then export it back to RTF or HTML.

High Performance

Because RichTextBox isn't built on the native WPF RichTextbox, it's much faster at loading and instantaneously editing large documents.

Rich Formatting

Edit and format text containing multiple fonts, decorations, colors, tables, images, lists, and more.

Insert and Edit Tables

Because RichTextBox supports many advanced table commands, it's easier for you to design tables in HTML documents. Insert new tables, rows, and columns with the click of a button. Specify individual cell borders, sizes, and text alignments. You can even merge cells and convert plain text to tables, just like in Microsoft Word.
