Visual ElementsDictionaries, Languages and API

Visual Elements

The DevExpress WinForms Spell Checker ships with all UI elements you'll need to fully replicate the spell checking user experience available in Microsoft Word or Microsoft Outlook.

Customizable Spell Checking Dialogs

Built-in spelling error indication forms.

Customizable Spell Checking Dialogs

Choose one of two spelling error indication dialogs - both replicate dialogs found in Microsoft Office (Outlook & Word). In addition, the control includes Dictionary dialogs so that end-users can add unrecognized words to their dictionary. As you would expect, end-users can build a custom word list as needs dictate.
Documentation

Spelling Options Dialog

Built-in spell checking options dialog.

Spelling Options Dialog

From general options such as "ignore uppercase" to editing custom dictionary entries and language selection, the Options Dialog allows end-users to modify spell checking behavior as necessary.
Documentation

Popup (Context) Menu

Integration with Popup Menus.

Popup (Context) Menu

You can automatically embed Custom Items (suggestions, etc) to the context menu to simplify error correction (without the need to invoke a dialog).
Documentation

Check-as-You-Type Mode

Intuitive error indication.

Check-as-You-Type Mode

Errors can be underlined using wavy red lines. The control automatically checks spelling as you type, word by word in a separate thread without affecting UI responsiveness.
Documentation
"The response from DevExpress is always prompt, detailed and typically includes a code sample. Have used their suite for 4 years and never regretted my choice for one second." Jim Thomas

Additional Info

WinForms UI Templates (EAP)

Jump start the form development process via polished and ready-to-use 'templates'. The motivation behind our WinForms UI Templates is to create ready-to-use UI solutions for real-life line-of-business (LOB) apps and eliminate the need for routine UI customizations. Read about UI Templates

Touch Enabled User Experience

Deliver elegant, touch-enabled WinForms applications using the platform you know and love. The WinForms Subscription helps you leverage your current investments and address customer needs via a comprehensive range of WinForms controls that support touch on Windows 8/10/11.

Sec 508 and Accessibility

The DevExpress WinForms Subscription makes it easy to create WinForms applications that meet government regulations regarding accessibility. Sec 508 and Accessibility Guidelines 1.0 support is available for DevExpress WinForms controls.

Straightforward Localization

All DevExpress WinForms controls can be localized using localization-related API or satellite resource assemblies. DevExpress delivers satellite assemblies for a large variety of languages and cultures. To help you get started, resource files for three cultures are included in our installation: German, Japanese, and Spanish. If you need to modify our shipping resources or create satellite assemblies for a different language, simply use our Online Localization Service or UI Localization Client tool.
Online Localization Service
UI Localization Client

Testing Support

The DevExpress Universal Subscription includes built-in support for Microsoft's CodedUI. Unlike many vendors claiming support for Coded UI through the simple use of MSAA, DevExpress controls go the extra mile to make certain that individual controls fully comply with Microsoft's testing framework. We don't simply support Coded UI; we support it to the maximum extent possible. Note: CodedUI support requires purchase of the DevExpress Universal Subscription. Learn more about Coded UI

MVVM Framework

The DevExpress MVVM Framework ships with features that are absent in WinForms, but essential to MVVM development. These missing features include bindings, commands, UI triggers, behaviors etc. Our Framework includes all of these along with a straightforward API to make WinForms app development more efficient.
