public event PivotFieldEventHandler FieldVisibleChanged
Public Event FieldVisibleChanged As PivotFieldEventHandler
The FieldVisibleChanged event's data class is PivotFieldEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| Field | Gets the field being processed. |
| 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. |
The FieldVisibleChanged event occurs after a field has been hidden, or a hidden field has been shown. To determine which field has been hidden or shown, use the event parameter’s PivotFieldEventArgs.Field property.
You can show (or hide) a field in code using the PivotGridField.Visible property. An end-user can do this via the context menu, drag-and-drop or using the Field List.
The PivotGridControl.FieldAreaChanged event is also raised when a field is hidden or shown. This event occurs before the FieldVisibleChanged event.
