wpf - AvalonDock 使用默认布局序列化和反序列化时不渲染布局

Question

我刚刚开始使用 AvalonDock，几天来我一直在苦苦挣扎。我正在尝试从反序列化的停靠管理器加载我的布局的平凡任务。我尝试了这篇文章所建议的(“AvalonDock DockingManager does not load layout”)，但屏幕仍然是空的。

我的 wpf 应用程序 xaml 如下:

<Window x:Name="frm_Main" x:Class="DataCAD.Forms.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:aD="http://schemas.xceed.com/wpf/xaml/avalondock"
    Title="MainWindow" Height="563.9" Width="832" WindowState="Maximized">
<Grid Margin="0,0,0,0">
    <Grid.ColumnDefinitions>
        <ColumnDefinition/>
        <ColumnDefinition Width="0*"/>
    </Grid.ColumnDefinitions>
    <Menu HorizontalAlignment="Left" Height="24" VerticalAlignment="Top" Width="{Binding ElementName=frm_Main,Path=ActualWidth}">

                <MenuItem.Icon>
                    <Image Width="24" Height="24" Source="/Images/cuiImport.png"/>
                </MenuItem.Icon>
            </MenuItem>
            <MenuItem Name="mnuFile_Exportcui" Padding="15,3,3,3" Header="Export Cuix" Click="MnuFile_Exportcui_OnClick">

            </MenuItem>
            <Separator />
            <MenuItem Name="mnuFile_Exit" Padding="15,3,3,3" Header="Exit" Click="MnuFile_Exit_OnClick"/>

    </Menu>

                    </aD:LayoutDocumentPaneGroup>
                </aD:LayoutPanel>
                <aD:LayoutAnchorablePaneGroup Orientation="Vertical" DockHeight="150" >
                    <aD:LayoutAnchorablePane DockHeight="150" >
                        <aD:LayoutAnchorable ContentId="output" Title="Output">
                            <TextBox x:Name="OutpuTextBox"></TextBox>

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

我的设置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">

    <LayoutPanel Orientation="Horizontal">
      <LayoutAnchorablePaneGroup Orientation="Vertical" 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">

  </RootPanel>
  <TopSide />
  <RightSide />
  <LeftSide />
  <BottomSide />
  <FloatingWindows />
  <Hidden />
</LayoutRoot>

我的代码如下:

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);
    }
}

非常感谢任何帮助。提前致谢。

我无法 Deserialize 我的布局的原因是我在 LoadLayout 方法中缺少 Serializer.LayoutSerializationCallback 事件。

新的 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);
}
