VirtualizingWrapPanel usage question

[arc95]

I'm using the VirtualizingWrapPanel and just get a flickering box. Here's my XAML:

<DataTemplate x:Key="ImageTemplate">
	<StackPanel Orientation="Vertical" Margin="12">
		<Image Width="195" Stretch="Fill" Source="{Binding Url}" ToolTipService.ShowDuration="9000000">
			<Image.ToolTip>
				<ToolTip DataContext="{Binding PlacementTarget, 
	RelativeSource={RelativeSource Self}}" HasDropShadow="True">
					<Border BorderBrush="Black" BorderThickness="0" Margin="5,7,5,5">
						<Image Source="{Binding Source}" Width="595" Stretch="Uniform" />
					</Border>
				</ToolTip>
			</Image.ToolTip>
		</Image>
		<TextBox FontWeight="Bold" Text="{Binding Filename, Mode=OneWay}" IsReadOnly="True" Margin="0 3 0 0"
				 Style="{StaticResource FieldTextBox}" Width="195" HorizontalContentAlignment="Center" />
	</StackPanel>
</DataTemplate>

<ListView ItemsSource="{Binding Images, UpdateSourceTrigger=PropertyChanged}" 
	VirtualizingStackPanel.IsVirtualizing="True"
	VirtualizingStackPanel.VirtualizationMode="Recycling"
	ScrollViewer.HorizontalScrollBarVisibility="Disabled"
	ItemTemplate="{StaticResource ImageTemplate}" Margin="25 0 25 25">
	<ListView.ItemsPanel>
		<ItemsPanelTemplate>
			<wpfControls:VirtualizingWrapPanel IsItemsHost="True" />
		</ItemsPanelTemplate>
	</ListView.ItemsPanel>
</ListView>

Got it! Needed to add height/width on the child container and remove VirtualizingStackPanel.IsVirtualizing="True" VirtualizingStackPanel.VirtualizationMode="Recycling".

Excellent! Glad you figured it out.

after connecting this panel, the sizes of items are all square and the sizes are not changed. I understand I need to manually register. Well, when a lot of elements, when scrolling the mouse wheel, top and bottom flash empty lines, fail to load.
