# How to: Use Spell Checking with a Context Menu
|
|
By default, when you enable spell checking in an editing control like <xref:System.Windows.Controls.TextBox> or <xref:System.Windows.Controls.RichTextBox>, you get spell-checking choices in the context menu. For example, when users right-click a misspelled word, they get a set of spelling suggestions or the option to **Ignore All**. However, when you override the default context menu with your own custom context menu, this functionality is lost, and you need to write code to reenable the spell-checking feature in the context menu. The following example shows how to enable this on a <xref:System.Windows.Controls.TextBox>.
|
|
|
|
## Example
|
|
The following example shows the [!INCLUDE[TLA#tla_xaml](../../../includes/tlasharptla-xaml-md.md)] that creates a <xref:System.Windows.Controls.TextBox> with some events that are used to implement the context menu.
|
|
|
|
[!code-xaml[TextBoxMiscSnippets_snip#SpellerCustomContextMenuExampleWholePage](~/samples/snippets/csharp/VS_Snippets_Wpf/TextBoxMiscSnippets_snip/csharp/speller_custom_context_menu.xaml#spellercustomcontextmenuexamplewholepage)]
|
|
|
|
## Example
|
|
The following example shows the code that implements the context menu.
|
|
|
|
[!code-csharp[TextBoxMiscSnippets_snip#SpellerCustomContextMenuCodeExampleWholePage](~/samples/snippets/csharp/VS_Snippets_Wpf/TextBoxMiscSnippets_snip/csharp/speller_custom_context_menu.xaml.cs#spellercustomcontextmenucodeexamplewholepage)]
|
|
[!code-vb[TextBoxMiscSnippets_snip#SpellerCustomContextMenuCodeExampleWholePage](~/samples/snippets/visualbasic/VS_Snippets_Wpf/TextBoxMiscSnippets_snip/visualbasic/speller_custom_context_menu.xaml.vb#spellercustomcontextmenucodeexamplewholepage)]
|
|
|
|
The code used for doing this with a <xref:System.Windows.Controls.RichTextBox> is similar. The main difference is in the parameter passed to the `GetSpellingError` method. For a <xref:System.Windows.Controls.TextBox>, pass the integer index of the caret position:
|
|
|
|
`spellingError = myTextBox.GetSpellingError(caretIndex);`
|
|
|
|
For a <xref:System.Windows.Controls.RichTextBox>, pass the <xref:System.Windows.Documents.TextPointer> that specifies the caret position:
|
|
|
|
`spellingError = myRichTextBox.GetSpellingError(myRichTextBox.CaretPosition);`
|
|
