CollectionViewSource::Filter Event

 

Provides filtering logic.

Namespace:   System.Windows.Data
Assembly:  PresentationFramework (in PresentationFramework.dll)

public:
event FilterEventHandler^ Filter {
	void add(FilterEventHandler^ value);
	void remove(FilterEventHandler^ value);
}

Views can apply a filter to a collection. This means that although an item might exist in the collection, a particular view is intended to show only a certain subset of the full collection.

You can use this event to set an event handler to provide filtering logic.

The following example shows how to set an event handler for the Filter event. In this example, listingDataView is an instance of CollectionViewSource.
