Integrated Spell Checker

The Liquid Spell Checker can be easily integrated with the Rich TextBox, all you need to do to enable this feature is to handle 2 events and to be in posession of a dictionary (.dic) file.  The main event here is CheckWord which is called by the Rich TextBox whenever a new word is typed or the cursor moves away from a word.  It is also called at the start when you set the RichText or HTML property, when this occurs this event is fired for each word in the document.

namespace RichTextBox
    public partial class Page : UserControl
        private SpellChecker _spellChecker;

        public Page()

            _spellChecker = new SpellChecker((this.GetType().Assembly.GetManifestResourceStream("RichTextBox.dictionary.en-US.dic")));

            richTextBox.CheckWord += new RichTextBoxEventHandler(richTextBox_WordEdited);
            richTextBox.IncorrectWordNotify += new RichTextBoxEventHandler(richTextBox_IncorrectWordNotify);
            richTextBox.IncorrectWordAdd += new RichTextBoxEventHandler(richTextBox_IncorrectWordAdd);

        private void BuildCustomDictionary()

        private void richTextBox_IncorrectWordAdd(object sender, RichTextBoxEventArgs e)

        private void richTextBox_IncorrectWordNotify(object sender, RichTextBoxEventArgs e)
            List<string> suggestions;

            suggestions = _spellChecker.GetSuggestions(e.Parameter);
            richTextBox.ShowSuggestions(suggestions, e);

        private void richTextBox_WordEdited(object sender, RichTextBoxEventArgs e)
            string temp = e.Parameter.ToLower();

            e.Cancel = _spellChecker.CheckWord(temp);

As you can see from the above example we handle CheckWord by calling the CheckWord method on the Spell Checker object.

The IncorrectWordNotify Event

We also handle the IncorrectWordNotify event, here we call the GetSuggestions() method of the Spell Checker object which returns a collection of suggestions, with these we call the ShowSuggestions() method of the Rich TextBox which renders the popup bubble.

The IncorrectWordAdd Event

In the Rich TextBox, if the user decides an incorrect word is in fact correct, they can click the Add button to include the word in a custom dictionary.  When this occurs the IncorrectWordAdd event is fired allowing you to add the word to a custom dictionary.  As you can see from this example the custom dictionary is implemented as a simple collection, in your own Silverlight applications you may want to store this list, either in the Silverlight isolated storage or web service call.
