WPF - scroll list in expander

I have an Expander in which I want to have a ListBox . When I open Expander , the ListBox simply expands the screen (instead of expanding to fill in what is available, and then scrolling).

Here is my XAML:

 <DockPanel Margin="266.25,0,455,12" Name="dockPanel1"> <StackPanel> <Expander Header="expander1" Name="expander1" Width="150" HorizontalAlignment="Left"> <Grid> <Label>Testing</Label> <ScrollViewer> <ListBox Name="lstBox" FontSize="14" SelectionChanged="lstBox_SelectionChanged" /> </ScrollViewer> </Grid> </Expander> <Expander Header="expander2" Name="expander2" Width="150" HorizontalAlignment="Left"> <Grid > </Grid> </Expander> </StackPanel> </DockPanel>

When Expander1 opens, it simply expands to the size of the ListBox (from the screen). If I put the size in the grid ( Height="275" ), it will not resize using the window.

I want it to stretch to the size of the window, but nothing more. Is there any way to do this?

You need to set the Height property for the ScrollViewer, otherwise it will be the same size as the child. Here are some updated versions of XAML:

 <DockPanel> <StackPanel> <Expander Header="expander1" Width="150" HorizontalAlignment="Left"> <StackPanel> <Label>Testing</Label> <ScrollViewer Height="75"> <ListBox> </ListBox> </ScrollViewer> </StackPanel> </Expander> <Expander Header="expander2"> </Expander> </StackPanel> </DockPanel>
