![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() ![]() | GetCustomDictionaries | Gets the collection of lexicon file locations that are used for custom spelling checkers on a specified text-editing control. |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() ![]() | GetIsEnabled | Returns a value that indicates whether the spelling checker is enabled on the specified text-editing control. |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() ![]() | SetIsEnabled | Enables or disables the spelling checker on the specified text-editing control, such as TextBox or RichTextBox. |

![]() ![]() | CustomDictionariesProperty | Identifies the CustomDictionaries dependency property. |
![]() ![]() | IsEnabledProperty | Identifies the IsEnabled dependency property. |

To enable the spelling checker, set the SpellCheck::IsEnabled property to true on a text-editing control. When this spelling checker is enabled, misspelled words are underlined by using a red wavy line, as shown in the following illustration. Spelling checker is supported only when WPF provides a default dictionary. In .NET Framework 4, WPF provides dictionaries for English, French, German, and Spanish.

To add a custom dictionary, add the location of the lexicon file to the CustomDictionaries collection.
The following example shows how to enable real-time spell checking in a TextBox by using the IsEnabled property of the SpellCheck class.
