Question

I´m filling a listbox with a specific data, the code works fine, but I need to add a scrollviewer to the listbox because there are many elements inside, I tried to use a ScrolViewer and put inside the listbox, but doesn’t work, here is the code

<StackPanel x:Name="Sites" Grid.Row="1"  Orientation="Vertical">
    <ListBox x:Name="ListSites" >
       <ListBox.ItemTemplate>
          <DataTemplate>
            <Button Width="460" Height="120" Click="click" Name="btn">
             <Button.Content>
              <StackPanel Orientation="Vertical" Height="100" Width="460">
                <TextBlock Width="460" Name="txtname" FontSize="22" Text="{Binding name}" Height="40" Foreground="CadetBlue" />
                <TextBlock Width="460" Name="txtUrl" FontSize="22" Text="{Binding Url}" Height="60"/>
               </StackPanel>
              </Button.Content>
              </Button>
             </DataTemplate>
         </ListBox.ItemTemplate>
      </ListBox>
  </StackPanel>

If the ListBox is not given infinite space for height then it should automatically scroll when items overflow its boundaries. For instance, if the second Grid row outside your stackpanel has explicit or ‘star’ height set, the scrollbar in the listbox will show up automatically.
