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;
}
}
}
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
