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

The Prefilter criteria can be changed by end-users at runtime, or in code via the PivotGridControl.PrefilterCriteria or PivotGridControl.PrefilterString property.
