AvalonDock在使用默認佈局序列化和反序列化時不渲染布局

我剛剛開始使用AvalonDock，我一直在牆上敲打我的頭幾天。我正在嘗試從反序列化的dockmanager中加載我的佈局的普通任務。我曾嘗試過這篇文章提出的（「AvalonDock DockingManager does not load layout」），並且仍然空着屏幕。AvalonDock在使用默認佈局序列化和反序列化時不渲染布局

我的WPF應用程序XAML是如下：

<Window x:Name="frm_Main" x:Class="DataCAD.Forms.MainWindow"

      </aD:LayoutPanel> 
     </aD:LayoutRoot> 
    </aD:DockingManager>

我的設置XML如下：

<?xml version="1.0" encoding="utf-8"?> 
    <LayoutRoot xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> 
    <RootPanel Orientation="Vertical"> 
    <LayoutPanel Orientation="Horizontal"> 
     <LayoutAnchorablePaneGroup Orientation="Vertical" DockWidth="150"> 
     <LayoutAnchorablePane DockWidth="150"> 
      <LayoutAnchorable AutoHideMinWidth="100" AutoHideMinHeight="100" Title="Cuix Explorer" IsSelected="True" ContentId="CuixExplorer" /> 
     </LayoutAnchorablePane> 
     <LayoutAnchorablePane DockWidth="150"> 
      <LayoutAnchorable AutoHideMinWidth="100" AutoHideMinHeight="100" Title="Properties" IsSelected="True" ContentId="Properties" /> 
     </LayoutAnchorablePane> 
     </LayoutAnchorablePaneGroup> 
     <LayoutDocumentPaneGroup Orientation="Vertical"> 
     <LayoutDocumentPane> 
      <LayoutDocument Title="default" IsSelected="True" IsLastFocusedDocument="True" ContentId="default" LastActivationTimeStamp="10/05/2013 00:30:01" /> 
     </LayoutDocumentPane> 
     </LayoutDocumentPaneGroup> 
    </LayoutPanel> 
    <LayoutAnchorablePaneGroup Orientation="Vertical" DockHeight="150"> 
     <LayoutAnchorablePane DockHeight="150"> 
     <LayoutAnchorable AutoHideMinWidth="100" AutoHideMinHeight="100" Title="Output" IsSelected="True" ContentId="output" /> 
     </LayoutAnchorablePane> 
    </LayoutAnchorablePaneGroup> 
    </RootPanel> 
    <TopSide /> 
    <RightSide /> 
    <LeftSide /> 
    <BottomSide /> 
    <FloatingWindows /> 
    <Hidden /> 
</LayoutRoot>

我的代碼如下：

public MainWindow() 
{ 
    InitializeComponent(); 
    LoadLayout(); 
    Left = Settings.Default.MAINWINDOW_LEFT; 
    Top = Settings.Default.MAINWINDOW_TOP; 
    Width = Settings.Default.MAINWINDOW_WIDTH; 
    Height = Settings.Default.MAINWINDOW_HEIGHT; 
    WindowState = (Settings.Default.MAINWINDOW_ISMAXIMIZED) ? WindowState.Maximized : WindowState.Normal; 
} 


private void MainWindow_OnClosing(object sender , CancelEventArgs cancelEventArgs) 
{ 

    Settings.Default.MAINWINDOW_LEFT = Left; 
    Settings.Default.MAINWINDOW_TOP = Top; 
    Settings.Default.MAINWINDOW_WIDTH = Width; 
    Settings.Default.MAINWINDOW_HEIGHT = Height; 
    Settings.Default.MAINWINDOW_ISMAXIMIZED = (WindowState == WindowState.Maximized); 
    Settings.Default.CUIXEXPLORER_ISVISIBLE = CuixExplorer.IsVisible; 
    Settings.Default.CUIXEXPLORER_DOCKLOCATION = CuixExplorer.PreviousContainerIndex; 
    Settings.Default.CUIXEXPLORER_WIDTH = CuixExplorer.FloatingWidth; 
    Settings.Default.CUIXEXPLORER_HEIGHT = CuixExplorer.FloatingHeight; 
    Settings.Default.Save(); 
    SaveLayout(); 
} 

private void SaveLayout() 
{ 
    var serializer = new XmlLayoutSerializer(Dockman); 

    using (var stream = new StreamWriter(_settingsFile)) 
    { 
     serializer.Serialize(stream); 
    } 
} 

private void LoadLayout() 
{ 
    var serializer = new XmlLayoutSerializer(Dockman); 
    using (var stream = new StreamReader(_settingsFile)) 
    { 
     serializer.Deserialize(stream); 
    } 
}

任何幫助不勝感激。提前致謝。

@弗蘭克的答案應該被標記爲「最好的」 ... – Mikant

我也碰到過這個問題，這個問題是不是回調。這是沒有必要的。在發生Window_Loaded事件之前，反序列化的方法將不起作用。如果之前像在這種情況下在窗口構造函數中調用它，則該對象未完全加載，因此無法正確加載xml。這樣做會導致白屏問題。

我從Syncfusion Docking Manager切換到Exceed Avalon Dock時遇到此錯誤。我只是改變了加載和保存的代碼，而不是它們被調用的地方。 Syncfusion Dock Manager加載DOES在調用構造函數時工作，而這個顯然不適用於此。沒什麼大不了的，Window_Loaded做這項工作。

我從超越阿瓦隆碼頭切換到獨立時所面臨的同樣的問題版本的AvalonDock 2.0.2000。在Window_Loaded中移動Deserialize方法對我很有用。 –

我之所以不能夠Deserialize我的佈局是因爲我在我的LoadLayout方法中缺少Serializer.LayoutSerializationCallback事件。

新LoadLayout方法：

public void LoadLayout() 
{ 
    var serializer = new XmlLayoutSerializer(DockingManagerMain); 

    // Imparitive for Deserialization 
    serializer.LayoutSerializationCallback += (s, args) => 
    { 
     args.Content = args.Content; 
    }; 

    serializer.Deserialize(DockingLayoutConfig); 
}

Franck的解決方案與代碼隱藏中的UserControl_Loaded事件一起使用。更好的一點是從屏幕繼承你的viewmodel並重寫OnViewLoaded（對象視圖）方法。在你的視圖的xaml中給你的dockmanager一個x：Name，以便你可以在OnViewLoaded方法中使用它。

像這樣（與TRAE Moore的代碼裏貝里的組合）：

protected override void OnViewLoaded(object view) 
{ 
    base.OnViewLoaded(view); 
    MyView v = view as MyView; 
    if (v?.myDockManager != null) { 
     var ser = new XmlLayoutSerializer(v.myDockManager); 
     // ... 
    } 
}
