I have a form with multiple rich text editors, all with custom spell checking.
I did have this code to set the spell checker:
System.InvalidOperationExceptionvar culture = CultureInfo.GetCultureInfo("en-AU");
var checker = (DocumentSpellChecker)radRichTextEditor1.SpellChecker;
if (!(checker.GetDictionary(culture) is AustralianDictionary))
{
checker.AddDictionary(AustralianDictionary.Instance, culture);
}
radRichTextEditor1.SpellChecker.SpellCheckingCulture = culture;
However, I found that I was using hundreds of megabytes of memory.
The work-around I used was to create a custom document spell checker:
public class CustomDocumentSpellChecker : DocumentSpellChecker
{
// Thread-safe thanks to the CLR
private static readonly CustomDocumentSpellChecker _instance = new CustomDocumentSpellChecker();
private CustomDocumentSpellChecker()
{
var culture = CultureInfo.GetCultureInfo("en-AU");
AddDictionary(AustralianDictionary.Instance, culture);
SpellCheckingCulture = culture;
}
public static CustomDocumentSpellChecker Instance
{
get
{
return _instance;
}
}
}
I then assigned the custom spell checker to the rich text editor:
radRichTextEditor1.SpellChecker = CustomDocumentSpellChecker.Instance;
I'm hoping this approach is reasonable, and that the spell checker won't have a problem with being assigned to multiple rich text editors.
