ListBox Styles and Templates
This topic describes the styles and templates for the ListBox control. You can modify the default ControlTemplate to give the control a unique appearance. For more information, see Customizing the Appearance of an Existing Control by Creating a ControlTemplate.
ListBox Parts
The ListBox control does not have any named parts.
When you create a ControlTemplate for a ListBox, your template might contain an ItemsPresenter within a ScrollViewer. (The ItemsPresenter displays each item in the ListBox; the ScrollViewer enables scrolling within the control). If the ItemsPresenter is not the direct child of the ScrollViewer, you must give the ItemsPresenter the name, ItemsPresenter.
