Event Data
The GroupFilterChanged event's data class is PivotGroupEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| Group | Gets the group for which the event has been raised. |
| 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. |
Remarks
The GroupFilterChanged event occurs after a user changes the filter condition in a filter drop-down, or the PivotGridGroup.FilterValues property is used to change the filter condition in code. To obtain the group whose filter condition is changed, use the event parameter’s PivotGroupEventArgs.Group property.
Note
The GroupFilterChanged event is raised only if the Field.FilterValues object model changes. Conditions (such as > , <, Contains and others) do not change the object model when you filter values in the Excel-style pop-up filter in the Filter Editor.
