ASPxSpellChecker.CustomDictionaryLoading Event

Fires when a custom dictionary is loading into a session.

Namespace: DevExpress.Web.ASPxSpellChecker

Assembly: DevExpress.Web.ASPxSpellChecker.v18.2.dll

Declaration

C#

public event CustomDictionaryLoadingEventHandler CustomDictionaryLoading

VB.NET

Public Event CustomDictionaryLoading As CustomDictionaryLoadingEventHandler

Event Data

The CustomDictionaryLoading event's data class is CustomDictionaryLoadingEventArgs. The following properties provide information specific to this event:

Property	Description
CustomDictionary	Gets the custom dictionary to be loaded.

Remarks

Handle the CustomDictionaryLoading event and use the ASPxSpellCheckerCustomDictionary.LoadFromStream method to load a custom dictionary, other than the default.

To save a custom dictionary when a word is added to it, handle the ASPxSpellChecker.WordAdded event.

The following code snippet illustrates that you can handle the ASPxSpellChecker.CustomDictionaryLoading event to load a custom dictionary from a stream. Note that the ASPxSpellChecker control already has an ASPxSpellCheckerCustomDictionary object in its collection of dictionaries. When the custom dictionary is loading, it fires an event allowing you to load a user-specific dictionary.
