I am using a scrollviewer control around my stack panel which contains an ItemsControl. When there are many items in the ItemsControl it is suppose to scroll but for some reason it just cuts of the items. Here is the code: 

<StackPanel>
    <ScrollViewer CanContentScroll="True" VerticalScrollBarVisibility="Visible">
        <ItemsControl  Name="icEvents" Width="Auto" Height="100"  Background="AliceBlue" 
                       ItemsSource="{Binding Path=EventSources}">
            <ItemsControl.ItemTemplate>
                <DataTemplate>
                    <StackPanel>
                        <TextBlock Text="Source:"/>
                        <TextBlock Text="{Binding Path=Source}" />
                        <TextBlock Text="Original Source:"/>
                        <TextBlock Text="{Binding Path=OriginalSource}" />
                    </StackPanel>
                </DataTemplate>
            </ItemsControl.ItemTemplate>
        </ItemsControl>
    </ScrollViewer>
</StackPanel>

    Try a grid around your ScrollViwer instead of the StackPanel. I think StackPanel will provide as much height as the internal content wants, so here the Scrollviwer doesn’t work properly since its height is not get restricted by its parent control.

    You can understand the issue from the example below.

    <StackPanel>
    <ScrollViewer>
        <ItemsControl >
            <Rectangle Stroke="#FFC3C3C3"  Height="300" Fill="Black" StrokeThickness="4" Width="200"/>
            <Rectangle Stroke="#FFC3C3C3" Width="200" Height="300" Fill="Black" StrokeThickness="4"/>
            <Rectangle Stroke="#FFC3C3C3" Height="300" Fill="Black" StrokeThickness="4" Width="200"/>
            <Rectangle Stroke="#FFC3C3C3" Width="200" Height="300" Fill="Black" StrokeThickness="4"/>
            <Rectangle Stroke="#FFC3C3C3"  Width="200" Height="300" Fill="Black" StrokeThickness="4"/>
        </ItemsControl>
    </ScrollViewer>
</StackPanel>

    Above code is similar to yours and it doesn’t give you scrollbars. But see the below code in which I changed only the StackPanel to a Grid(Any panel which respects the size of its children based on panels size but stackpanel doesn’t)

    <Grid>
    <ScrollViewer>
        <ItemsControl >
            <Rectangle Stroke="#FFC3C3C3"  Height="300" Fill="Black" StrokeThickness="4" Width="200"/>
            <Rectangle Stroke="#FFC3C3C3" Width="200" Height="300" Fill="Black" StrokeThickness="4"/>
            <Rectangle Stroke="#FFC3C3C3" Height="300" Fill="Black" StrokeThickness="4" Width="200"/>
            <Rectangle Stroke="#FFC3C3C3" Width="200" Height="300" Fill="Black" StrokeThickness="4"/>
            <Rectangle Stroke="#FFC3C3C3"  Width="200" Height="300" Fill="Black" StrokeThickness="4"/>
        </ItemsControl>
    </ScrollViewer>
</Grid>

    UPDATE : But if you really need to use StackPanel then you might need to set the size for your ScrollViwer to get the Content scroll
