Event Data
The PrefilterCriteriaChanged event's data class is RoutedEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| Handled | Gets or sets a value that indicates the present state of the event handling for a routed event as it travels the route. |
| OriginalSource | Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class. |
| RoutedEvent | Gets or sets the RoutedEvent associated with this RoutedEventArgs instance. |
| Source | Gets or sets a reference to the object that raised the event. |
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. |
| 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. |
Remarks
Users can change the Prefilter criteria at runtime. Use the PivotGridControl.PrefilterCriteria or PivotGridControl.PrefilterString property to change the Prefilter criteria in code.
Note
The PrefilterCriteriaChanged event is not raised when you set filters in the Excel-style pop-up filter or in the Filter Editor. Use the PivotGridControl.FilterCriteriaChanged event instead.
