how to make working custom dictionary in wpf richtextbox

Question

I've tried to add custom dictionary (*.lex format, utf-16 encode) in RichTextBox to make spellcheck, but it doesn't works. If i using such code for TextBox, it works.

private void SpellCheckInit()
{   
    // this works            
    txt_Box.SpellCheck.CustomDictionaries.Add(new Uri(@"C:\dictionary.lex"));

    // dictionary language is russian, but this setting makes spellcheck works                  
    txt_Box.Language = System.Windows.Markup.XmlLanguage.GetLanguage("en-GB");
    txt_Box.SpellCheck.IsEnabled = true;

    // this doesn't works
    richtxt.SpellCheck.CustomDictionaries.Add(new Uri(@"C:\dictionary.lex"));
    var ruLang = System.Windows.Markup.XmlLanguage.GetLanguage("ru");
    var enLang = System.Windows.Markup.XmlLanguage.GetLanguage("en-GB");
    richtxt.Language = ruLang;

    // or richtxt.Language = enLang; there are no difference for working
    richtxt.SpellCheck.IsEnabled = true; 
}

I've already added #LID1049 in dictionary, but it has no effect. Do you know how to fix this?

There are two ways adding custom dictionaries

The first custom dictionary (customwords.lex) is added in XAML

<RichTextBox Margin="38,18,40,0" Name="richTextBox1" Height="45" VerticalAlignment="Top" SpellCheck.IsEnabled="True" >
<SpellCheck.CustomDictionaries>
    <!-- customwords.lex is included as a content file-->
    <sys:Uri>pack://application:,,,/customwords.lex</sys:Uri>
</SpellCheck.CustomDictionaries>

and the Second The second custom dictionary (customwords2.lex) is added in the event handler, The file is included as a resource file and compiled into the application assembly that is named WPFCustomDictionary

private void button1_Click(object sender, RoutedEventArgs e)
{
    IList dictionaries = SpellCheck.GetCustomDictionaries(richTextBox1);
    // customwords2.lex is included as a resource file
    dictionaries.Add(new Uri(@"pack://application:,,,/WPFCustomDictionary;component/customwords2.lex"));
}

Does this works for you???
