When a xaml page has more than one ListBox on it and both have a selected item, only the first ListBox will scroll to the selected item.

Details (expand)

.NET Framework 4.5

Create two classes :

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace App1.Entities
{
    public class ContentEntity
    {
        public int Id { get; set; }
        public string Content { get; set; }
    }
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace App1.Entities
{
    public class ListOfContent
    {
        List<ContentEntity> contentList;

        public List<ContentEntity> ObjectList
        {
            get
            {
                return contentList;
            }
            set
            {
                contentList = value;
            }
        }
    }
}

Create a simple page with this XAML:

<Page
    x:Class="App1.ListUsingCustomControl"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:App1"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d">

    <Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}">
<StackPanel x:Name="sp">
            <TextBlock Name="txt1" Text="Listbox 1" />
            <ListBox Name="lst1" Height="100"/>
            <TextBlock Name="txt2" Text="Listbox 2"/>
            <ListBox Name="lst2" Height="100"/>
        </StackPanel>
    </Grid>
</Page>

---------------------------
Put this C# code in the constructor:

this.InitializeComponent();

            var l = new List<ContentEntity>();

            for (var i = 1; i < 20; i++)
            {
                var c = new ContentEntity();
                c.Id = i;
                c.Content = "Cont " + i.ToString();
                l.Add(c);
            }

            var lobj = new ListOfContent();
            lobj.ObjectList = l;
            lst1.ItemsSource = lobj.ObjectList;
            lst1.SelectedValuePath = "Id";
            lst1.DisplayMemberPath = "Content";
            lst1.SelectedValue = 8;

            lst2.ItemsSource = lobj.ObjectList;
            lst2.SelectedValuePath = "Id";
            lst2.DisplayMemberPath = "Content";
            lst2.SelectedValue = 8;
