InputLanguageChangingEventArgs Class

Provides data for the InputLanguageChanging event.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in

public class InputLanguageChangingEventArgs : CancelEventArgs
public class InputLanguageChangingEventArgs extends CancelEventArgs
public class InputLanguageChangingEventArgs extends CancelEventArgs

You can use the data from the InputLanguageChangingEventArgs class to prepare to change Input Method Editors (IME) or swap right-to-left values. You can also change a thread's CurrentCulture and CurrentUICulture properties so that different resources get picked up. To prevent the input language from changing, set the Cancel property to true.

An InputLanguageChangingEventArgs identifies the requested input language and the character set of new input language. The Culture property identifies the locale of the requested language.

The InputLanguageChanging event precedes the InputLanguageChanged event.

For information about handling events, see Consuming Events.
