Windows Phone How to Vertical Scroll

Question

I'm just starting out in WinPhone development and can't figure out how to set the vertical scroll. For example i've started a new Pivot App, and this code allows the user to scroll up and d own to see all the entries:

<controls:PivotItem Header="Login">
    <!--Double line list with text wrapping-->
    <ListBox x:Name="FirstListBox" Margin="0,0,-12,0" ItemsSource="{Binding Items}">
        <ListBox.ItemTemplate>
            <DataTemplate>
              <StackPanel Margin="0,0,0,17" Width="432" Height="78">
                  <TextBlock Text="{Binding LineOne}" TextWrapping="Wrap" Style="{StaticResource PhoneTextExtraLargeStyle}"/>
                  <TextBlock Text="{Binding LineTwo}" TextWrapping="Wrap" Margin="12,-6,12,0" Style="{StaticResource PhoneTextSubtleStyle}"/>
              </StackPanel>
            </DataTemplate>
        </ListBox.ItemTemplate>
    </ListBox>
</controls:PivotItem>

Now when, I add my own pivot item, with a stackpanel with more items than can be seen on the screen at any one time, it will not allow me to scroll to see them all. What am I missing here?

Thanks.

Answer 1

Add ScrollViewer over the StackPanel and it will make it scrollable.

Answer 2

The ListBox in the example code that you supplied ha built-in scrolling functionality. However, if you are not using something that already has this scrolling functionality in it, you will have to add a ScrollViewer.

<controls:PivotItem Header="Example">
    <ScrollViewer Margin="12,0,12,0">
        <StackPanel>
            <TextBlock Text="Example1" FontSize="150" />
            <TextBlock Text="Example2" FontSize="150" />
        </StackPanel>
    </ScrollViewer>
</controls:PivotItem>
