FrameworkElement.IsInitialized 属性

定义

命名空间:
System.Windows
程序集:
PresentationFramework.dll

获取一个值，该值表示该元素是否在由 XAMLXAML 处理器进行处理时，或者通过显式调用其 EndInit() 方法被初始化。Gets a value that indicates whether this element has been initialized, either during processing by a XAMLXAML processor, or by explicitly having its EndInit() method called.

public:
 property bool IsInitialized { bool get(); };
public bool IsInitialized { get; }
member this.IsInitialized : bool
Public ReadOnly Property IsInitialized As Boolean

属性值

Boolean

如果该元素按照前面提到的 XAMLXAML 处理或者方法调用已被初始化，则为 true；否则为 false。true if the element is initialized per the aforementioned XAMLXAML processing or method calls; otherwise, false.

注解

如果此元素已在逻辑树中移动，以使其具有新的父元素，并因此再次加载，则此属性也可能 true。This property may also be true if this element has been moved within the logical tree such that it has a new parent element, and therefore becomes reloaded again.

如果还在使用 BeginInit 和 EndInit，则此属性很有用。This property is useful if you also are using BeginInit and EndInit. 可以确保初始化由 XAMLXAML 处理器加载的逻辑树中的元素。Elements in the logical tree that is loaded by a XAMLXAML processor are assured to be initialized. 调用 EndInit 时，将初始化不在逻辑树中的元素。Elements not in the logical tree are initialized when EndInit is called. 如果没有任何特定的 BeginInit 和 EndInit处理，则在构造函数返回初始化的结果后，就会发生这种情况。In absence of any specific handling of BeginInit and EndInit, this will happen as soon as the constructor returns the initialized result.
