  • RadSpell

    RadSpell enables developers to add multilingual spellchecking capabilities to their ASP.NET applications. The component is completely customizable and can be attached to any server/client editable element (textbox, div, iframe). It currently supports 20 languages with custom dictionaries for every language.

    RadSpell can use three spellcheck algorithms to provide the most adequate spelling suggestions for your language. The algorithms are selected by setting the SpellCheckProvider property to one of the following values:

    • PhoneticProvider, TelerikProvider: This provider uses phonetic codes to provide "sounds like" word suggestions. Really effective for English, but less so for other languages. The TelerikProvider is the default value of the SpellCheckProvider property and is equivalent to PhoneticProvider.

    • EditDistanceProvider: This provider uses the edit distance algorithm. EditDistanceProvider work best for non-western languages. The EditDistanceProvider has a specific setting, called EditDistance, which controls the count of the suggested words and affects the performance of the spellcheck algorithm.

    • MicrosoftWordProvider: This provider automates Microsoft Word via its COM Interop interface. You need to have installed Microsoft Word on your server in order to use this provider. For more information on how to enable the MS Word spell checking see this article: Enabling MS Word Spell Checking.

    Key Features

    • No-postback algorithm for superior performance
    • Options: check all caps, check words with numbers, etc.
    • Custom dictionary for every language
    • Support for subject-specific dictionaries (i.e. medical)
    • Optional phonetic algorithm
    • Ignoring inline scripts and style definitions
    • Ignoring text fragments
    • Ability to check multiple controls at once

    Note: The ImageButton value of the ButtonType property renders a link with assigned .rscLinkImg class that can be used to modify the look of the rendered control.
