public event GroupChangedEventHandler Changed
Public Event Changed As GroupChangedEventHandler
The Changed event's data class is GroupChangedEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| ChangeType | Gets a value that indicates what caused the group to change. |
| Handled | Gets or sets a value that indicates the present state of the event handling for a routed event as it travels the route. Inherited from RoutedEventArgs. |
| OriginalSource | Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class. Inherited from RoutedEventArgs. |
| RoutedEvent | Gets or sets the RoutedEvent associated with this RoutedEventArgs instance. Inherited from RoutedEventArgs. |
| Source | Gets or sets a reference to the object that raised the event. Inherited from RoutedEventArgs. |
The event data class exposes the following methods:
| Method | Description |
|---|---|
| InvokeEventHandler(Delegate, Object) | When overridden in a derived class, provides a way to invoke event handlers in a type-specific way, which can increase efficiency over the base implementation. Inherited from RoutedEventArgs. |
| OnSetSource(Object) | When overridden in a derived class, provides a notification callback entry point whenever the value of the Source property of an instance changes. Inherited from RoutedEventArgs. |
Handle the Changed event to respond to changing the field group.
Use the event parameter’s GroupChangedEventArgs.ChangeType property to determine whether the group has been changed by expanding or collapsing a field header, or in any other way.
