Probably all of you know it, still want to share this simple trick that I learn, and it is “How to turn spell check on your wpf text input controls”.
What property do turn it?
SpellCheck.IsEnabled = “True”
This functionality is defined it System.windows.controls.spellcheck class, and the attach property SpellCheck.IsEnabled can be used with Textbox and RickTextBox control.
Note that appropriate language pack should be installed in the system to get full spell check support.
Unfortunately didn’t find defaults for adding new item to the dictionary, but found some articles on the net to handle the add to dictionary.
