Übersicht über Alignment, Margin und Padding
Von der FrameworkElement-Klasse werden verschiedene Eigenschaften verfügbar gemacht, die verwendet werden können, um untergeordnete Elemente genau zu positionieren. In diesem Thema werden vier der wichtigsten Eigenschaften erläutert: HorizontalAlignment, Margin, Padding und VerticalAlignment. Es ist wichtig, die Auswirkungen dieser Eigenschaften zu verstehen, da sie die Grundlage zur Steuerung der Elementpositionierung in Windows Presentation Foundation (WPF)-Anwendungen darstellen.
Dieses Thema enthält folgende Abschnitte.

Einführung in die Elementpositionierung
Es gibt zahlreiche Möglichkeiten, Elemente mit WPF zu positionieren. Zur Erstellung eines idealen Layouts ist es jedoch nicht ausreichend, einfach nur die richtigen Panel-Elemente auszuwählen. Zur Feinsteuerung der Positionierung sollten Sie die Eigenschaften HorizontalAlignment, Margin, Padding und VerticalAlignment verstehen.
In der folgenden Abbildung ist ein Layoutszenario dargestellt, in dem verschiedene Positionierungseigenschaften verwendet werden.
Auf den ersten Blick erscheint die Positionierung der Button-Elemente in dieser Abbildung zufällig. Tatsächlich sind ihre Positionen jedoch durch eine Kombination von Rändern, Ausrichtungen und Abständen exakt festgelegt.
Im folgenden Beispiel wird das Erstellen des Layouts für die oben dargestellte Abbildung beschrieben. Ein Border-Element kapselt einen übergeordneten StackPanel mit einem Padding-Wert von 15 geräteunabhängigen Pixeln. Hieraus ergibt sich, dass der schmale LightBlue-Streifen, das untergeordnete Element StackPanel umgibt. Die untergeordneten Elemente des StackPanel werden verwendet, um alle der verschiedenen in diesem Thema ausführlich beschriebenen Positionierungseigenschaften darzustellen. Drei Button-Elemente werden verwendet, um die Eigenschaften Margin und HorizontalAlignment zu veranschaulichen.

Die folgende Abbildung enthält eine vergrößerte Ansicht der verschiedenen Positionierungseigenschaften, die im vorherigen Beispiel verwendet werden. In den folgenden Abschnitten dieses Themas wird die Verwendung jeder Positionierungseigenschaft ausführlich beschrieben.
Alignment-Eigenschaften
Von den Eigenschaften HorizontalAlignment und VerticalAlignment wird festgelegt, an welcher Stelle im zugewiesenen Layoutbereich eines übergeordneten Elements ein untergeordnetes Element positioniert wird. Untergeordnete Elemente können mit diesen beiden Eigenschaften exakt positioniert werden. Von den untergeordneten Elementen eines DockPanel können beispielsweise vier verschiedene horizontale Ausrichtungen festgelegt werden: Left, Right, Center sowie Stretch, um den verfügbaren Platz auszufüllen. Ähnliche Werte sind für die vertikale Positionierung verfügbar.
![]() |
---|
Explizit festgelegte Eigenschaften Height und Width haben in einem Element Vorrang vor dem Stretch-Eigenschaftswert.Wenn die Werte für Height, Width und HorizontalAlignment auf Stretch festgelegt werden, wird die Stretch-Anforderung ignoriert. |
HorizontalAlignment-Eigenschaft
Von der HorizontalAlignment-Eigenschaft werden die horizontalen Ausrichtungscharakteristiken deklariert, die auf untergeordnete Elemente angewendet werden. In der folgenden Tabelle ist jeder mögliche Wert für die HorizontalAlignment-Eigenschaft aufgeführt.
Member |
Beschreibung |
---|---|
Untergeordnete Elemente werden im übergeordneten Element am linken Rand des zugewiesenen Layoutbereichs ausgerichtet. |
|
Untergeordnete Elemente werden im zugewiesenen Layoutbereich des übergeordneten Elements zentriert ausgerichtet. |
|
Untergeordnete Elemente werden im übergeordneten Element am rechten Rand des zugewiesenen Layoutbereichs ausgerichtet. |
|
Stretch (Standard) |
Untergeordnete Elemente werden gestreckt, sodass sie den zugewiesenen Layoutbereich des übergeordneten Elements ausfüllen. Explizite Werte für Width und Height haben Vorrang. |
Im folgenden Beispiel ist dargestellt, wie die HorizontalAlignment-Eigenschaft auf Button-Elemente angewendet wird. Jeder Attributwert wird angezeigt, um die verschiedenen Renderingverhalten besser zu veranschaulichen.
Dim myButton1 As New Button()
myButton1.HorizontalAlignment = Windows.HorizontalAlignment.Left
myButton1.Margin = New Thickness(20)

Stretch (Standard) |
Untergeordnete Elemente werden gestreckt, sodass sie den zugewiesenen Layoutbereich des übergeordneten Elements ausfüllen. Explizite Werte für Width und Height haben Vorrang. |
Im folgenden Beispiel ist dargestellt, wie die VerticalAlignment-Eigenschaft auf Button-Elemente angewendet wird. Jeder Attributwert wird angezeigt, um die verschiedenen Renderingverhalten besser zu veranschaulichen. Für dieses Beispiel wird als übergeordnetes Element ein Grid-Element mit sichtbaren Rasterlinien verwendet, um das Layoutverhalten für jeden Eigenschaftswert besser zu veranschaulichen.

Das durch den vorherigen Code erstellte Layout ähnelt der folgenden Abbildung. In der Abbildung werden die Auswirkungen der einzelnen VerticalAlignment-Werte auf die Positionierung dargestellt.
Margin-Eigenschaften
Die Margin-Eigenschaft beschreibt die Entfernung zwischen einem Element und seinem untergeordneten Element oder Peers. Margin-Werte können einheitlich sein, mit Syntax wie Margin="20". Mit dieser Syntax wird ein einheitlicher Margin-Wert von 20 geräteunabhängigen Pixeln auf das Element angewendet. Sie können auch vier verschiedene Margin-Werte festlegen, von denen jeder einen unterschiedlichen Abstand für den linken, oberen, rechten und unteren Rand (in dieser Reihenfolge) darstellt, beispielsweise Margin="0,10,5,25". Wenn Sie die Margin-Eigenschaft ordnungsgemäß verwenden, können Sie die Renderingposition eines Elements und dessen unter- und nebengeordneten Elementen sehr präzise steuern.
![]() |
---|
Wenn der Wert für den Rand ungleich Null ist, wird der entsprechende Abstand außerhalb der ActualWidth und ActualHeight des Elements hinzugefügt. |
Im folgenden Beispiel wird dargestellt, wie einheitliche Ränder um eine Gruppe von Button-Elementen hinzugefügt werden. Die Button-Elemente werden gleichmäßig mit einem Randpuffer von zehn Pixel in jeder Richtung platziert.
Dim myButton7 As New Button
myButton7.Margin = New Thickness(10)
myButton7.Content = "Button 7"
Dim myButton8 As New Button
myButton8.Margin = New Thickness(10)
myButton8.Content = "Button 8"
Dim myButton9 As New Button
myButton9.Margin = New Thickness(10)
myButton9.Content = "Button 9"
Button myButton7 = new Button();
myButton7.Margin = new Thickness(10);
myButton7.Content = "Button 7";
Button myButton8 = new Button();
myButton8.Margin = new Thickness(10);
myButton8.Content = "Button 8";
Button myButton9 = new Button();
myButton9.Margin = new Thickness(10);
myButton9.Content = "Button 9";
Button^ myButton7 = gcnew Button();
myButton7->Margin = Thickness(10);
myButton7->Content = "Button 7";
Button^ myButton8 = gcnew Button();
myButton8->Margin = Thickness(10);
myButton8->Content = "Button 8";
Button^ myButton9 = gcnew Button();
myButton9->Margin = Thickness(10);
myButton9->Content = "Button 9";
<Button Margin="10">Button 7</Button>
<Button Margin="10">Button 8</Button>
<Button Margin="10">Button 9</Button>
In vielen Fällen ist ein einheitlicher Rand nicht geeignet. In diesen Fällen kann ein ungleichmäßiger Abstand angewendet werden. Im folgenden Beispiel wird dargestellt, wie ein ungleichmäßiger Abstand auf untergeordnete Elemente angewendet wird. Die Ränder werden in folgender Reihenfolge festgelegt: links, oben, rechts, unten.
Dim myButton1 As New Button
myButton1.Margin = New Thickness(0, 10, 0, 10)
myButton1.Content = "Button 1"
Dim myButton2 As New Button
myButton2.Margin = New Thickness(0, 10, 0, 10)
myButton2.Content = "Button 2"
Dim myButton3 As New Button
myButton3.Margin = New Thickness(0, 10, 0, 10)
Button myButton1 = new Button();
myButton1.Margin = new Thickness(0, 10, 0, 10);
myButton1.Content = "Button 1";
Button myButton2 = new Button();
myButton2.Margin = new Thickness(0, 10, 0, 10);
myButton2.Content = "Button 2";
Button myButton3 = new Button();
myButton3.Margin = new Thickness(0, 10, 0, 10);
Button^ myButton1 = gcnew Button();
myButton1->Margin = Thickness(0, 10, 0, 10);
myButton1->Content = "Button 1";
Button^ myButton2 = gcnew Button();
myButton2->Margin = Thickness(0, 10, 0, 10);
myButton2->Content = "Button 2";
Button^ myButton3 = gcnew Button();
myButton3->Margin = Thickness(0, 10, 0, 10);
<Button Margin="0,10,0,10">Button 1</Button>
<Button Margin="0,10,0,10">Button 2</Button>
<Button Margin="0,10,0,10">Button 3</Button>
Padding-Eigenschaft
Padding entspricht Margin in nahezu jeder Hinsicht. Die Padding-Eigenschaft ist vor allem aus Gründen der Einfachheit nur in wenigen Klassen verfügbar: Block, Border, Control, und TextBlock sind Beispiele für Klassen, in denen die Padding-Eigenschaft verfügbar ist. Die Padding-Eigenschaft vergrößert die effektive Größe eines untergeordneten Elements um den festgelegten Thickness-Wert.
Im folgenden Beispiel wird dargestellt, wie die Padding-Eigenschaft auf ein übergeordnetes Border-Element angewendet wird.
Dim myBorder As New Border
myBorder.Background = Brushes.LightBlue
myBorder.BorderBrush = Brushes.Black
myBorder.BorderThickness = New Thickness(2)
myBorder.CornerRadius = New CornerRadius(45)
myBorder.Padding = New Thickness(25)
myBorder = new Border();
myBorder.Background = Brushes.LightBlue;
myBorder.BorderBrush = Brushes.Black;
myBorder.BorderThickness = new Thickness(2);
myBorder.CornerRadius = new CornerRadius(45);
myBorder.Padding = new Thickness(25);
myBorder = gcnew Border();
myBorder->Background = Brushes::LightBlue;
myBorder->BorderBrush = Brushes::Black;
myBorder->BorderThickness = Thickness(2);
myBorder->CornerRadius = CornerRadius(45);
myBorder->Padding = Thickness(25);
<Border Background="LightBlue"
BorderBrush="Black"
BorderThickness="2"
CornerRadius="45"
Padding="25">
Verwenden von Alignment, Margin und Padding in einer Anwendung
Mithilfe von HorizontalAlignment, Margin, Padding und VerticalAlignment kann die Positionierung zum Erstellen einer komplexen user interface (UI) gesteuert werden. Sie können diese Eigenschaften verwenden, um die Positionierung untergeordneter Elemente zu ändern und beim Erstellen dynamischer Anwendungen die Flexibilität und Benutzerfreundlichkeit zu erhöhen.
Im folgenden Beispiel werden alle in diesem Thema beschriebenen Konzepte veranschaulicht. Ausgehend von der im ersten Beispiel dieses Themas dargestellten Infrastruktur wird in diesem Beispiel ein Grid-Element als untergeordnetes Element des Border-Objekts im ersten Beispiel hinzugefügt. Padding wird auf das übergeordnete Border-Element angewendet. Das Grid-Element wird verwendet, um den Bereich zwischen drei untergeordneten StackPanel-Elementen aufzuteilen. Die Button-Elemente werden auch hier verwendet, um die verschiedenen Auswirkungen der Eigenschaften Margin und HorizontalAlignment darzustellen. TextBlock-Elemente werden jedem ColumnDefinition-Element hinzugefügt, um die unterschiedlichen Eigenschaften genauer festzulegen, die auf die Button-Elemente in jeder Spalte angewendet werden.

Mithilfe der durch die FrameworkElement-Klasse festgelegten Positionierungseigenschaften können Sie die Platzierung von Elementen innerhalb von -Anwendungen genau steuern. Es stehen Ihnen nun mehrere Verfahren zur Verfügung, mit denen Sie unter Verwendung von WPF Elemente besser positionieren können.
Zusätzliche Ressourcen sind verfügbar, in denen das WPF-Layout ausführlicher beschrieben wird. Im Thema Übersicht über Panel-Elemente finden Sie weitere Informationen zu den verschiedenen Panel-Elementen. Im Thema Exemplarische Vorgehensweise: Erste Schritte mit WPF werden fortgeschrittene Techniken eingeführt, in denen Layoutelemente verwendet werden, um Komponenten zu positionieren und ihre Aktionen an Datenquellen zu binden.
