Methoden

The StackPanel Klasse hat diese Methoden. Es erbt auch Methoden von Object Klasse.

MethodeBeschreibung
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. (Geerbt von UIElement)
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. (Geerbt von UIElement)
ArrangeOverride Provides the behavior for the Arrange pass of layout. Classes can override this method to define their own Arrange pass behavior. (Geerbt von FrameworkElement)
CancelDirectManipulations Cancels ongoing direct manipulation processing (system-defined panning/zooming) on any ScrollViewer parent that contains the current UIElement. (Geerbt von UIElement)
CapturePointer Sets pointer capture to a UIElement. Once captured, only the element that has capture will fire pointer-related events. (Geerbt von UIElement)
ClearValue Clears the local value of a dependency property. (Geerbt von DependencyObject)
FindName Retrieves an object that has the specified identifier name. (Geerbt von FrameworkElement)
FindSubElementsForTouchTargeting Enables a UIElement subclass to expose child elements that assist with resolving touch targeting. (Geerbt von UIElement)
GetAnimationBaseValue Returns any base value established for a dependency property, which would apply in cases where an animation is not active. (Geerbt von DependencyObject)
GetBindingExpression Returns the BindingExpression that represents the binding on the specified property. (Geerbt von FrameworkElement)
GetIrregularSnapPoints Returns the set of distances between irregular snap points for a specified orientation and alignment.
GetRegularSnapPoints Gets the distance between regular snap points for a specified orientation and alignment.
GetValue Returns the current effective value of a dependency property from a DependencyObject. (Geerbt von 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. (Geerbt von FrameworkElement)
InvalidateArrange Invalidates the arrange state (layout) for a UIElement. After the invalidation, the UIElement will have its layout updated, which will occur asynchronously. (Geerbt von UIElement)
InvalidateMeasure Invalidates the measurement state (layout) for a UIElement. (Geerbt von UIElement)
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. (Geerbt von 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. (Geerbt von 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. (Geerbt von FrameworkElement)
OnCreateAutomationPeer When implemented in a derived class, returns class-specific AutomationPeer implementations for the Microsoft UI Automation infrastructure. (Geerbt von UIElement)
OnDisconnectVisualChildren Override this method to implement how layout and logic should behave when items are removed from a class-specific content or children property. (Geerbt von UIElement)
ReadLocalValue Returns the local value of a dependency property, if a local value is set. (Geerbt von DependencyObject)
ReleasePointerCapture Releases pointer captures for capture of one specific pointer by this UIElement. (Geerbt von UIElement)
ReleasePointerCaptures Releases all pointer captures held by this element. (Geerbt von UIElement)
RemoveHandler Removes the specified routed event handler from this UIElement. Typically the handler in question was added by AddHandler. (Geerbt von UIElement)
SetBinding Attaches a binding to a FrameworkElement, using the provided binding object. (Geerbt von FrameworkElement)
SetValue Sets the local value of a dependency property on a DependencyObject. (Geerbt von DependencyObject)
TransformToVisual Returns a transform object that can be used to transform coordinates from the UIElement to the specified object. (Geerbt von UIElement)
UpdateLayout Ensures that all positions of child objects of a UIElement are properly updated for layout. (Geerbt von UIElement)

Beispiele

Im folgenden Beispiel wird veranschaulicht, wie ein StackPanel mit Elementen erstellt wird.


<StackPanel Margin="20">
    <Rectangle Fill="Red" Width="50" Height="50" Margin="5" />
    <Rectangle Fill="Blue" Width="50" Height="50" Margin="5" />

Im folgenden Codebeispiel wird die Insert-Methode verwendet, um ein Element an einer bestimmten Stelle in ein vorhandenes StackPanel-Steuerelement einzufügen.


<Grid x:Name="LayoutRoot"  Width="500" Height="500">
    <StackPanel x:Name="MyStackPanel">
        <TextBlock x:Name="TB1" Text="First Name" Width="77" HorizontalAlignment="Left"/>
        <TextBlock x:Name="TB2" Text="Last Name" Width="78" HorizontalAlignment="Left"/>
        <TextBlock x:Name="TB3" Text="Address" Width="60" HorizontalAlignment="Left"/>
    </StackPanel>
</Grid>



private void Rearrange()
{
    TextBlock TB4 = new TextBlock();
    TB4.Text = "Age";
    MyStackPanel.Children.Insert(2, TB4);
    
}
