与Caliburn Micro一起使用AvalonDock

我试图将AvalonDock 2.8与Caliburn Micro 2.0.2一起使用。以下是我目前有：与Caliburn Micro一起使用AvalonDock

MainView.xaml：

<Window x:Class="MainView" 
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
     xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
     xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
     xmlns:cal="http://www.caliburnproject.org" 
     xmlns:xcad="http://schemas.xceed.com/wpf/xaml/avalondock" 
     xmlns:local="clr-namespace:CaliburnMicroAndAvalonDock" 
     mc:Ignorable="d" 
     Title="MainWindow" Height="350" Width="525"> 
    <Grid> 
     <Grid.RowDefinitions> 
      <RowDefinition Height="40"/> 
      <RowDefinition Height="*"/> 
     </Grid.RowDefinitions> 

     <Button x:Name="Open" Content="Open new document" Margin="5"/> 

     <xcad:DockingManager Grid.Row="1" DocumentsSource="{Binding Items}"> 
      <xcad:DockingManager.LayoutItemContainerStyle> 
       <Style TargetType="{x:Type xcad:LayoutItem}"> 
        <Setter Property="Title" Value="{Binding Model.DisplayName}" /> 
       </Style> 
      </xcad:DockingManager.LayoutItemContainerStyle> 

      <xcad:DockingManager.LayoutItemTemplateSelector> 
       <local:LayoutItemTemplateSelector> 
        <local:LayoutItemTemplateSelector.Template> 
         <DataTemplate> 
          <ContentControl cal:View.Model="{Binding .}" IsTabStop="False"/> 
         </DataTemplate> 
        </local:LayoutItemTemplateSelector.Template> 
       </local:LayoutItemTemplateSelector> 
      </xcad:DockingManager.LayoutItemTemplateSelector> 

      <xcad:LayoutRoot> 
       <xcad:LayoutPanel Orientation="Horizontal"> 
        <xcad:LayoutDocumentPane/> 
       </xcad:LayoutPanel> 
      </xcad:LayoutRoot> 
     </xcad:DockingManager> 
    </Grid> 
</Window>

MainViewModel.vb：

Imports Caliburn.Micro 

Public Class MainViewModel 
    Inherits Conductor(Of Screen).Collection.OneActive 

    Private m_Index As Int32 = 0 

    Sub Open() 
    ActivateItem(New DocumentViewModel With {.DisplayName = $"Document {m_Index}"}) 
    m_Index += 1 
    End Sub 

End Class

Document.xaml：

<UserControl x:Class="DocumentView" 
      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
      xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
      xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
      xmlns:local="clr-namespace:CaliburnMicroAndAvalonDock" 
      mc:Ignorable="d" 
      d:DesignHeight="300" d:DesignWidth="300"> 
    <Grid> 
     <TextBlock Text="{Binding DisplayName}"/> 
    </Grid> 
</UserControl>

DocumentViewModel.vb：

Imports Caliburn.Micro 

Public Class DocumentViewModel 
    Inherits Screen 

End Class

个

LayoutItemTemplateSelector.vb：

Public Class LayoutItemTemplateSelector 
    Inherits DataTemplateSelector 

    Public Property Template As DataTemplate 

    Public Overrides Function SelectTemplate(item As Object, container As DependencyObject) As DataTemplate 
    Return Me.Template 
    End Function 

End Class

部分它的工作原理，问题是，鉴于失败Cannot find view for System.Windows.Controls.ContentPresenter错误加载：

我很新的这两个卡利Micro和AvalonDock，所以我的代码很大程度上基于我在网上找到的例子（例如this）。但这些样本相当陈旧，并且不适用于当前版本的AvalonDock（2.8.15465.16500）。如果我切换到较旧的（2.0.2000），它工作正常。

我设法解决这个问题的帮助this answer和this explanation。这是更新的代码LayoutItemTemplateSelector.vb：

Public Class LayoutItemTemplateSelector 
    Inherits DataTemplateSelector 

    Public Property Template As DataTemplate 

    Public Overrides Function SelectTemplate(item As Object, container As DependencyObject) As DataTemplate 
    If TypeOf item Is DocumentViewModel Then 
     Return Me.Template 
    Else 
     Return MyBase.SelectTemplate(item, container) 
    End If 
    End Function 

End Class
