The following shows the implementation of the example ShowOnlyBargainsFilter filter event handler. This event handler uses the Accepted property to filter out AuctionItem objects that have a CurrentPrice of $25 or greater.
Private Sub ShowOnlyBargainsFilter(ByVal sender As Object, ByVal e As FilterEventArgs) Dim product As AuctionItem = CType(e.Item, AuctionItem) If Not (product Is Nothing) Then 'Filter out products with price 25 or above If product.CurrentPrice < 25 Then e.Accepted = True Else e.Accepted = False End If End If End Sub
