Vorgehensweise: Bereich mithilfe des DockPanel-Elements aufteilen

Im folgenden Beispiel wird ein einfaches Benutzeroberflächenframework mit einem DockPanel-Element erstellt. DockPanel teilt den verfügbaren Bereich auf seine untergeordneten Elemente auf.

Beispiel

Dieses Beispiel verwendet die Dock-Eigenschaft, bei der es sich um eine angefügte Eigenschaft handelt, um zwei identische Border-Elemente an das Top-Element des aufgeteilten Bereichs anzudocken. Ein drittes Border-Element wird an das Leftangedockt, wobei die Breite auf 200 Pixel festgelegt ist. Ein viertes Border-Element wird an das Bottom-Element des Bildschirms angedockt. Das letzte Border-Element füllt automatisch den verbleibenden Platz aus.

Hinweis

Standardmäßig füllt das letzte untergeordnete Element eines DockPanel-Elements den verbleibenden verfügbaren Bereich aus. Wenn Sie dieses Verhalten nicht wünschen, legen Sie LastChildFill="False"fest.

Die kompilierte Anwendung liefert eine neue Benutzeroberfläche, die wie folgt aussieht.
