ListView::SearchForVirtualItem Event

Occurs when the ListView is in virtual mode and a search is taking place.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public:
 event SearchForVirtualItemEventHandler^ SearchForVirtualItem {
	void add (SearchForVirtualItemEventHandler^ value);
	void remove (SearchForVirtualItemEventHandler^ value);
}

This event occurs when a ListView is in virtual mode and the FindNearestItem or FindItemWithText method is called. When handling this event, you should calculate which item from the list of items supplied by the Items property matches the search criteria and set the SearchForVirtualItemEventArgs::Index property to the index of the ListViewItem. If an item is not provided, FindNearestItem and FindItemWithText will return nullptr.

For more information about handling events, see Consuming Events.

The following code example demonstrates the use of this member. In the example, a search returns the nearest match to a specified integer in a list of the first ten thousand squares. This code example is part of a larger example provided for the VirtualMode property.
