Examples

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

C#

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.

C#

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;
        }
    }
}
