方法

The ListBox 类 具有这些方法。 它还继承方法于Object 类.

方法说明
AddHandler Adds a routed event handler for a specified routed event, adding the handler to the handler collection on the current element. Specify handledEventsToo as true to have the provided handler be invoked even if the event is handled elsewhere. (继承自UIElement)
ApplyTemplate Loads the relevant control template so that its parts can be referenced. (继承自Control)
Arrange Positions child objects and determines a size for a UIElement. Parent objects that implement custom layout for their child elements should call this method from their layout override implementations to form a recursive layout update. (继承自UIElement)
ArrangeOverride Provides the behavior for the Arrange pass of layout. Classes can override this method to define their own Arrange pass behavior. (继承自FrameworkElement)
CancelDirectManipulations Cancels ongoing direct manipulation processing (system-defined panning/zooming) on any ScrollViewer parent that contains the current UIElement. (继承自UIElement)
CapturePointer Sets pointer capture to a UIElement. Once captured, only the element that has capture will fire pointer-related events. (继承自UIElement)
ClearContainerForItemOverride Undoes the effects of the PrepareContainerForItemOverride method. (继承自ItemsControl)
ClearValue Clears the local value of a dependency property. (继承自DependencyObject)
ContainerFromIndex Returns the container for the item at the specified index within the ItemCollection. (继承自ItemsControl)
ContainerFromItem Returns the container corresponding to the specified item. (继承自ItemsControl)
FindName Retrieves an object that has the specified identifier name. (继承自FrameworkElement)
FindSubElementsForTouchTargeting Enables a UIElement subclass to expose child elements that assist with resolving touch targeting. (继承自UIElement)
Focus Attempts to set the focus on the control. (继承自Control)
GetAnimationBaseValue Returns any base value established for a dependency property, which would apply in cases where an animation is not active. (继承自DependencyObject)
GetBindingExpression Returns the BindingExpression that represents the binding on the specified property. (继承自FrameworkElement)
GetContainerForItemOverride Creates or identifies the element that is used to display the given item. (继承自ItemsControl)
GetTemplateChild Retrieves the named element in the instantiated ControlTemplate visual tree. (继承自Control)
GetValue Returns the current effective value of a dependency property from a DependencyObject. (继承自DependencyObject)
GoToElementStateCore When implemented in a derived class, enables per-state construction of a visual tree for a control template in code, rather than by loading XAML for all states at control startup. (继承自FrameworkElement)
IndexFromContainer Returns the index to the item that has the specified, generated container. (继承自ItemsControl)
InvalidateArrange Invalidates the arrange state (layout) for a UIElement. After the invalidation, the UIElement will have its layout updated, which will occur asynchronously. (继承自UIElement)

IsItemItsOwnContainerOverride Determines whether the specified item is (or is eligible to be) its own container. (继承自ItemsControl)

Measure Updates the DesiredSize of a UIElement. Typically, objects that implement custom layout for their layout children call this method from their own MeasureOverride implementations to form a recursive layout update. (继承自UIElement)
MeasureOverride Provides the behavior for the Measure pass of the layout cycle. Classes can override this method to define their own Measure pass behavior. (继承自FrameworkElement)
OnApplyTemplate Invoked whenever application code or internal processes (such as a rebuilding layout pass) call ApplyTemplate. In simplest terms, this means the method is called just before a UI element displays in your app. Override this method to influence the default post-template logic of a class. (继承自FrameworkElement)
OnCreateAutomationPeer When implemented in a derived class, returns class-specific AutomationPeer implementations for the Microsoft UI Automation infrastructure. (继承自UIElement)

备注

使用 ListBox 控件来显示用户可以从中选择的项列表。一次可以显示 ListBox 控件中的多个项。可以指定 ListBox 控件是否允许多重选择,方法是使用 SelectionMode 属性。使用 SelectedItems 属性,您可以获取或设置列表框中的选定项。

若要填充 ListBox 控件,可以通过使用 ListBoxItem 类将项直接添加到 Items 集合,或者通过将 ItemsSource 属性绑定到数据源。

示例

此示例演示如何将 FontFamily 对象的集合直接添加到 ListBox 控件中。


            <ListBox>
                <ListBoxItem>
                    <TextBlock Text="Arial" FontFamily="Arial"/>
                    </ListBoxItem>
                <ListBoxItem>
                    <TextBlock Text="Courier New" FontFamily="Courier New" />
                    </ListBoxItem>
                <ListBoxItem>
                    <TextBlock Text="Times New Roman" FontFamily="Times New Roman"/>
                    </ListBoxItem>
            </ListBox>

此示例使用数据绑定用 FontFamily 对象的集合填充一个 ListBox 控件。设置 ItemTemplate 属性,以便字体系列的名称出现在指定的字体系列中。


            <ListBox>
                <ListBoxItem>
                    <TextBlock Text="Arial" FontFamily="Arial"/>
                    </ListBoxItem>
                <ListBoxItem>
                    <TextBlock Text="Courier New" FontFamily="Courier New" />
                    </ListBoxItem>
                <ListBoxItem>
                    <TextBlock Text="Times New Roman" FontFamily="Times New Roman"/>
                    </ListBoxItem>
            </ListBox>



        public BlankPage()
        {
            this.InitializeComponent();
            ObservableCollection<FontFamily> fonts = new ObservableCollection<FontFamily>();
            fonts.Add(new FontFamily("Arial"));
            fonts.Add(new FontFamily("Courier New"));
            fonts.Add(new FontFamily("Times New Roman"));

            FontsList.DataContext = fonts;
        }
