Why should I use ComponentOne's editor for WinForms?
Rich XHTML content management
You can store richly formatted text as XHTML in your database and manage it in your application using the Editor control.
Intuitive WinForms rich text editor
Replace text boxes with an intuitive editor and edit XHTML content in a familiar MS Word-like interface.
Reliable HTML rendering
ComponentOne Editor for WinForms is built using the WebView2 control, which is based on the Microsoft Edge browser, so all HTML content displays as expected.

Key Features of the WinForms Rich Text Editor
List of Services
-
Insert images, tables, and linksList Item 1Insert and manipulate various types of objects, such as tables, images, and hyperlinks, into your document. Dialog boxes allow you to modify all properties of inserted or edited objects.
-
Apply HTML styles and headersList Item 2Apply quick styles to text, just like in Microsoft Word. Since the editor uses HTML as its underlying content, these styles are converted to heading tags and inline styles.
-
spell checkList Item 3The WinForms editor has ComponentOne SpellChecker built-in, so you can use all the spell checking features, including dialog mode, "as you type" mode, context menu spelling suggestions, and auto-replace functionality.
Additional features
Flexible data binding
Easily bind to external data sources. Both display text and underlying XML are bindable, allowing you to easily bind unformatted text or full HTML markup to a data source.
Import and save documents
Loads an XHTML document into the WinForms Editor control from a file, stream, or XML string. Similarly, you can save the document to a file or stream.
XML document synchronization
When a bound document is edited within the editor, the underlying XML document is synchronized to match. Any changes to the XML document are displayed in the Editor control at runtime.
Customizing CSS styles
The WinForms editor fully supports CSS in edited documents. You can define external CSS styles that are used only in design or preview mode. Load CSS from a file or stream.
Adding custom tags to the DTD
Advanced programming tasks sometimes require the use of additional DTD elements in an edited document. You can add tags to a document by specifying tags in XML extended attributes.
Find and Replace dialog box
The editor includes a built-in dialog box that allows end users to specify search strings and word replacement options. You can also use your own Find/Replace dialog box.
Unlimited change history
The editor features an unlimited undo history mechanism. Undo and redo also support keyboard shortcuts. By repeatedly undoing, end users can incrementally rework and correct mistakes. The edit history can be accessed programmatically.
Clipboard support
You can select text, tables, or graphics using the clipboard's cut, copy, and paste operations. You can also paste HTML content into the WinForms text editor as formatted or plain text.
Preview and Print
The WinForms Editor control supports printing and print preview. Use Preview mode to view your document. Print directly from code or from the Print Preview dialog box, which is launched from the built-in toolbar.

Provides syntax highlighting function
You can use the rich text editor to provide custom syntax highlighting. We provide a sample demonstrating how to highlight formatted C# text.
Implementing a desktop chat editor
The rich text editor lets you create a simple chat editor with formatting options and emoticons. Text is managed as XHTML, but is displayed as rich, formatted content.
A rich text editor for the .NET Framework
For .NET Framework 4.8 applications, you can use the legacy C1Editor control, which is built on top of the .NET WebBrowser control.
This previous version of C1Editor supports source code viewing, built-in toolstrip, image and table support, revision history, printing, CSS support, find and replace, XHTML cleanup routines, and spell checking.
