Methods

	Name	Description

Remarks

ListBox is a control that displays a collection of items. More than one item in a ListBox is visible at a time. You specify whether the ListBox allows multiple selections by using the SelectionMode property.

ListBox is an ItemsControl. You set its content by using the Items or ItemsSource properties. For more information about content models, see Control Content Models. You can either populate the ListBox control directly, or bind it to a collection of items. For more information about populating a ListBox, see How to: Display Data in a ListBox.

The following illustration shows a ListBox control that contains some unbound text items.

ListBox Control

Customizing the ListBox Control

To apply the same property settings to multiple ListBox controls, use the Style property. You can apply a style to each item displayed in the ListBox by setting the ItemContainerStyle property. To change the visual structure and visual behavior of a ListBox, copy and modify its default style and template. For more information, see Control Customization.

Dependency properties for this control might be set by the default style of the control. If a dependency property for a ListBox is set by its default style, the property might change from its default value when the ListBox appears in the application. For more information, see Dependency Property Value Precedence. You can get the default style and template for ListBox from ListBox Styles and Templates.

Note:
Setting a visual property will only have an effect if that property is both present in ListBox control's default template and is set by using a TemplateBinding. You can find a list of visual properties in the "Changing the Visual Structure of a Control" section of Customizing the Appearance of an Existing Control by Using a ControlTemplate.

Version Notes

Silverlight for Windows Phone

Scrolling performance improvements have been made for the ListBox control in Windows Phone OS 7.1, which affect how some ScrollViewer properties are updated and when events occur. The following table describes the differences in behavior for Windows Phone OS 7.0 and Windows Phone OS 7.1.

Behavior	Windows Phone OS 7.0 app/Windows Phone OS 7.0 device	Windows Phone OS 7.0 or Windows Phone OS 7.1 app/Windows Phone OS 7.1 device
ScrollViewer properties are updated on the UI thread during scrolling.	Properties updated as soon as values change.	Properties updated when the user lifts their finger or when the user drags, pans or flicks ¼ of the screen, in any direction.
ManipulationDelta events raised on UI thread when dragging inside of a ScrollViewer.	Events are available for handling by elements in the ScrollViewer.	Events are not raised since they are on the input thread.

If your application depends on the Windows Phone OS 7.0 behavior, you can opt out of the performance improvements by setting the ManipulationMode property on the ScrollViewer associated with the ListBox to Control. The following code example shows how to do this.

<ListBox ItemsSource="{Binding Items}" ScrollViewer.ManipulationMode ="Control" Height="652" Canvas.Top="80">

Examples

The following code example creates a page with several ListBox controls configured in a variety of ways.
