RapidSpellDialog provides all the usual GUI features, add, undo, options, change, change all, ignore, ignore all, smart suggestions and double word detection. It interactively checks ANY TextBoxBase derived component such as TextBox and RichTextBox as well as 3rd Party Controls such as "TX Text Control". Checks selections, whole documents with wrap at end, highlights errors, accepts manual corrections, allows user to edit main document during spell check and also supports an editable user dictionary.

RapidSpellAsYouType functions like your users will expect. Spelling errors are highlighted as the user types, cuts/pastes, block deletes and loads files. This was the first .NET control to persistently highlight errors as the user continues to work (type, scroll etc). Right-clicking on a highlight presents a context menu with suggestions and options to 'Ignore All' or 'Add' to user dictionary. Includes English/Customizable Autocorrect. Works with TextBox and RichTextBox subclassed controls included in the product. Only one instance of RapidSpellAsYouType is needed for all text boxes on a form.

The customizable options forms provide the user with several spell checking options and the ability to modify the contents of their 'user dictionary' (if activated).

As you type and dialog checking are supported under Windows Forms. Current support for WPF includes dialog based checking of WPF's TextBox and RichTextBox controls.

The API was designed to provide for easy customization. The dialog GUIs can be redesigned by simply modifying the UI source code in the VS designer, source is included in the demo projects. The spell checker engine is 'decoupled' from the GUI making it possible to use custom word parsers with the GUI.

The RapidSpellDialog and RapidSpellAsYouType controls can be set to check multiple text boxes on a form, this means that only one instance is used which speeds up design and improves efficiency.

The non GUI component provides core functionality and ease of use - you pass the text you want checked and then iterate through each misspelled word finding suggestions and correcting as you go. You have access to the corrected text at any time.

Dict Manager, allows RapidSpell Dict files to be customized and created using other word lists.
