Hi Yu Sky,

It seems you have hit a bug in the ListBox . I have double checked for a problem in  our RadDataPager , but it appears an issue with the ListBox.
To check this , you can add a simple TextBlock bound to the count of the paged source. You will definitely see it shows the correct count,

Now the solution :

You may subscribe to the PageIndexChanged  event of RadDataPager and reset the source of the list box inside the event handler , such as :

    this.radDataPager.PageIndexChanged += new EventHandler<Telerik.Windows.Controls.PageIndexChangedEventArgs>(radDataPager_PageIndexChanged);
}

void radDataPager_PageIndexChanged(object sender, Telerik.Windows.Controls.PageIndexChangedEventArgs e)
{
    var cachedSource = this.itemsControl.ItemsSource;
    this.itemsControl.ItemsSource = null;
    this.itemsControl.ItemsSource = cachedSource;
}

All the best,

Hi Pavel，
Thanks for reply! Is this because of the ItemSource has not refreshed when the page index has changed? This works,thanks.
