Hinweise

Größer der value von einer angegebenen element, desto höher die Wahrscheinlichkeit der element im Vordergrund angezeigt werden soll.The greater the value of a given element, the more likely the element is to appear in the foreground. Ebenso, wenn ein element verfügt über eine relativ geringe value, element wird wahrscheinlich im Hintergrund angezeigt.Likewise, if an element has a relatively low value, the element will likely appear in the background. Z. B. eine element , bei dem ein value 5 werden oben angezeigt werden ein element , bei dem ein value von 4, die wiederum oben angezeigt wird ein element mit dem Wert von 3 und So weiter.For example, an element that has a value of 5 will appear above an element that has a value of 4, which in turn will appear above an element that has a value of 3, and so on. Negative Werte sind zulässig, und sie behalten Sie dieses Vorrangsmuster Vorrang.Negative values are allowed, and they continue this precedence pattern.

Mitglieder einer Children Auflistung, die gleich ZIndex Werte werden gerendert, in der Reihenfolge, in dem sie in der visuellen Struktur angezeigt werden.Members of a Children collection that have equal ZIndex values are rendered in the order in which they appear in the visual tree. Sie können die Indexposition eines untergeordneten Elements durch Durchlaufen der Member des bestimmen die Children Auflistung.You can determine the index position of a child by iterating the members of the Children collection.
