While I'm using such a construction in my code and typing russian text in a textbox nothing happens:
<TextBox SpellCheck.IsEnabled="True" />
While I'm using this construction english text is spell-checked but not russian
<TextBox xml:lang="en-US" SpellCheck.IsEnabled="True" />
What I'm doing wrong? How do I check spelling of other languages? Or maybe somebody can advice me a control which checks russian?
