我可以將InitializeComponent（）移動到Loaded（）

Question

在應用程序構造函數中不調用依賴項屬性設置程序，並且值僅在加載用戶控件後纔可用。那麼，將InitializeComponent()方法移至Loaded()方法是否安全？

Answer 1

我不知道這是否與您的問題有所幫助，但我只是讓VisualStateManger轉到它在加載事件當前狀態：

private void OnLoaded(object sender, RoutedEventArgs routedEventArgs) 
    { 
     VisualStateManager.GoToState(this, YourStateGroup.CurrentState.Name, false); 
    } 

Answer 2

保持InitializeComponent()的位置。相反，請使用Loaded事件。即

[Dependency] 
    public Foo Foo { get; set; } 

    public MainWindow() 
     { 
      InitializeComponent(); 

      Loaded += MainWindow_Loaded; 
     } 

    private void MainWindow_Loaded(object sender, System.Windows.RoutedEventArgs e) 
     { 
      // Propery injection should have taken place now, so do what you need to do with them 
     }
