Spell Checker is a non-visual extension used to check the spelling of text contained in text editing controls.

To learn more about Spell Checker and see it in action, refer to its online demos.

Implementation Details

Spell Checker is represented by the SpellCheckerExtension class. Its instance can be accessed via the ExtensionsFactory.SpellChecker helper method, which is used to add a Spell Checker extension to a view. This method's parameter provides access to the Spell Checker settings implemented by the SpellCheckerSettings class, allowing you to fully customize the extension.

Declaration

Spell Checker can be added to a view in the following manner.

View ("Index"):

@Html.Action("HomePartial")

@Html.TextArea("textBox", new { style = "width: 100%; height: 150px;"})

Partial View - "HomePartial":

@Html.DevExpress().SpellChecker(settings =>
{
    settings.Name = "SpellChecker";
    settings.CallbackRouteValues = new { Controller = "Home", Action = "HomePartial" };

    settings.CheckedElementID = "textBox";
    settings.Culture = new System.Globalization.CultureInfo("en-US");
    settings.Dictionaries.AddISpellDictionary(d =>
    {
        d.AlphabetPath = "~/Dictionaries/EnglishAlphabet.txt";
        d.GrammarPath = "~/Dictionaries/english.aff";
        d.DictionaryPath = "~/Dictionaries/american.xlg";
        d.CacheKey = "ispellDic";
        d.Culture = new System.Globalization.CultureInfo("en-US");
        d.EncodingName = "Western European (Windows)";
    });
}).GetHtml()
Note

The Partial View should contain only the extension's code.

Controller ("Home"):

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View();
    }

    public ActionResult HomePartial()
    {
        return PartialView("HomePartial");
    }
}

The code result is demonstrated in the image below.
