在XAML 元素上声明数据绑定时,它们通过查看其即时 DataContext 属性解析数据绑定。 数据上下文通常是绑定源对象用于评估绑定源值路径的。 可以在绑定中重写此行为,并设置特定的 绑定源对象 值。 如果未设置DataContext属性,则会检查承载绑定的对象的父元素的DataContext属性,依次向上检查,直到 XAML 对象树的根节点为止。
移除項目容器的兩個典型情況是當項目從基礎集合移除時,以及當虛擬化在 ItemsControl 上啟用時。 在這些情況下,項目容器的 DataContext 屬性會設定為 BindingOperations.DisconnectedSource 靜態屬性所傳回的 Sentinel 物件。 您應該先檢查 DataContext 是否等於 DisconnectedSource 物件,再存取項目容器的 DataContext。
