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