<ScrollViewer>
<ItemsControl Name="itemsControl">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel ItemWidth="{Binding ElementName=sizeSlider, Path=Value}"
FlowDirection="LeftToRight" Height="auto" Width="auto"
HorizontalAlignment="Left" Name="wrapPanel1"
VerticalAlignment="Top"
Margin="5"
>
</WrapPanel>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
</ItemsControl>
</ScrollViewer>
</StackPanel>
Your ScrollViewer is inside StackPanel which resizes to its content (either vertically or horizontally depending on its orientation). Place it either directly in a Window, a cell of a Grid, or a DockPanel for scroll bars to show up.
