Fix: Scrollbars of ListBox control aren't displayed correctly on a Windows Embedded Compact 7-based device


Consider the following scenario:
  • You run a Microsoft Silverlight for Windows Embedded application on a Windows Embedded Compact 7-based device.
  • The application has a UserControl control that contains a ListBox control.
    Note The ListBox controldoes not contain enough items to trigger the vertical scrollbar to be displayed.
  • You remove the ListBox control from a visual tree.
  • You update the ItemsSource property of the ListBox controlso that enough items are available to trigger the vertical scrollbar to be displayed.
  • You add the ListBox controlback to the visual tree.

In this scenario, the thumb element of the vertical scrollbar on the ListBox control is not displayed.

Note This issue also occurs on the horizontal scrollbar when the ListBox control contains a long item that triggers the horizontal scrollbar to be displayed.
