Spell- Checking Textbox in WPF using Expression Blend

The System.Windows.Controls.SpellCheck class provides real-time spell-checking functionality fortext-editing controls.

When enabled on a TextBox or RichTextBox control, as the user types text

into the control, any unrecognized words are underlined in red. If the user right-clicks a highlighted

word, they get a context menu, and they can select to replace the word from a set ofsuggested alternatives.
