ListView : how to always scroll to the bottom

I have a list view that I want to scroll to the bottom as I add items into the "Items" list.

As I add items they appear in the ListView, but when I reach the limit of the screen, the list remains showing the top section and new items are added to the bottom. If I scroll down I can see the new items. I'd like it to auto scroll to the bottom so that I can always see the latest items in the list.

<ListView 
         x:Name="lvBasketContent" 
         Grid.Row="1" 
         ItemsSource="{Binding Items}"
         ItemContainerStyle="{StaticResource ListViewItemStyle1}" 
         HorizontalContentAlignment="Stretch"
         VerticalContentAlignment="Bottom" 
         SelectionMode="None" 
         IsSwipeEnabled="False" 
         VerticalAlignment="Top"
         >

Can anyone help me out please?

Do you can try put this in your code ? Each time you add an item to your listbox , try call it

//Add an item in the listbox
lvBasketContent.Items.Add(...);

//...

//Scroll to bottom
lvBasketContent.SelectedIndex = lvBasketContent.Items.Count -1
lvBasketContent.ScrollIntoView(lvBasketContent.SelectedItem)

You need to create a custom behavior or derived implementation of ListView.

This class should monitor the ItemsSource collection for changes and call ListViewBase.ScrollIntoView(Object), passing in the item that you want to show. In your case, this may be the last one added.

I recommended the behavior as it keeps your code modular as you can use it on any listview in your solution by changing the xaml only.

I'm not going to write the code for you as behaviors are a very useful technique to learn first hand. The first link should give you all you need to get cracking.
