Property Value

Type: System.Object

The object that the filter should test. The default is null.

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

listingDataView.Filter += new FilterEventHandler(ShowOnlyBargainsFilter);

The following example shows the implementation of the example ShowOnlyBargainsFilter filter event handler. This event handler uses the FilterEventArgs.Accepted property to filter out AuctionItem objects that have a CurrentPrice of $25.00 or greater.

private void ShowOnlyBargainsFilter(object sender, FilterEventArgs e)
{
    AuctionItem product = e.Item as AuctionItem;
    if (product != null)
    {
        // Filter out products with price 25 or above
        if (product.CurrentPrice < 25)
        {
            e.Accepted = true;
        }
        else
        {
            e.Accepted = false;
        }
    }
}
