C# 如何在wpf项目中固定avalondock选项卡的位置

我在WPF项目中使用Avalondock创建包含布局文档的多个选项卡。是否有方法固定选项卡的位置，以便用户不能拖动和交换选项卡的位置

以下是我的代码：

<avalonDock:DockingManager  Grid.Row="1" x:Name="dockManager" AllowMixedOrientation="True" ActiveContentChanged="dockManager_ActiveContentChanged" Loaded="dockManager_Loaded" Mouse.MouseDown="dockManager_MouseDown">
    <avalonDock:DockingManager.Theme>
            <avalonDock:AeroTheme/>
        </avalonDock:DockingManager.Theme>
        <avalonDock:DockingManager.DocumentHeaderTemplate>
            <DataTemplate>

                <StackPanel Orientation="Horizontal">

                    <Image Source="{Binding IconSource}" Margin="0,0,4,0"/>
                    <TextBlock Text="{Binding Title , NotifyOnTargetUpdated=True}" TextTrimming="CharacterEllipsis" TargetUpdated="TextBlock_TargetUpdated" PreviewMouseDown="TextBlock_PreviewMouseDown"/>
                    <TextBlock Visibility="{Binding IsVisible}" />
                </StackPanel>


            </DataTemplate>
        </avalonDock:DockingManager.DocumentHeaderTemplate>

    <avalonDock:LayoutRoot x:Name="layout">
        <avalonDock:LayoutPanel Orientation="Horizontal" DockWidth="450" DockMinWidth="200" >
            <avalonDock:LayoutDocumentPane DockWidth="100*" x:Name="documentPane" >
                            <avalonDock:LayoutDocument CanClose="False" CanFloat="False"  ContentId="doc1" FloatingWidth="100">
                                <StackPanel>
                                <Frame BorderThickness="2" NavigationUIVisibility="Hidden"   x:Name="Mainframe" Source="{Binding DisplayPage, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />

                                </StackPanel>
                            </avalonDock:LayoutDocument>
                        </avalonDock:LayoutDocumentPane>


                </avalonDock:LayoutPanel>

            </avalonDock:LayoutRoot>

    </avalonDock:DockingManager>

在LayoutDocument中设置CanFloat=false

<avalonDock:DockingManager  Grid.Row="1" x:Name="dockManager" AllowMixedOrientation="True" ActiveContentChanged="dockManager_ActiveContentChanged" Loaded="dockManager_Loaded" Mouse.MouseDown="dockManager_MouseDown">
<avalonDock:DockingManager.Theme>
        <avalonDock:AeroTheme/>
    </avalonDock:DockingManager.Theme>
    <avalonDock:DockingManager.DocumentHeaderTemplate>
        <DataTemplate>
            <StackPanel Orientation="Horizontal">
                <Image Source="{Binding IconSource}" Margin="0,0,4,0"/>
                <TextBlock Text="{Binding Title , NotifyOnTargetUpdated=True}" TextTrimming="CharacterEllipsis" TargetUpdated="TextBlock_TargetUpdated" PreviewMouseDown="TextBlock_PreviewMouseDown"/>
                <TextBlock Visibility="{Binding IsVisible}" />
            </StackPanel>
        </DataTemplate>
    </avalonDock:DockingManager.DocumentHeaderTemplate>
  <avalonDock:LayoutRoot x:Name="layout">
    <avalonDock:LayoutPanel Orientation="Horizontal" DockWidth="450" DockMinWidth="200" CanFloat="False">
        <avalonDock:LayoutDocumentPane DockWidth="100*" x:Name="documentPane"  >
            <avalonDock:LayoutDocument CanClose="False" CanFloat="False"  ContentId="doc1" FloatingWidth="100">
               <StackPanel>
                  <Frame BorderThickness="2" NavigationUIVisibility="Hidden"   x:Name="Mainframe" Source="{Binding DisplayPage, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
                </StackPanel>
            </avalonDock:LayoutDocument>
        </avalonDock:LayoutDocumentPane>
            </avalonDock:LayoutPanel>
     </avalonDock:LayoutRoot>
</avalonDock:DockingManager>

在LayoutDocumentPane中设置

CanRespositionItems=“False”

 <avalonDock:LayoutDocumentPane DockWidth="100*" x:Name="documentPane" CanRepositionItems="False">
                        <avalonDock:LayoutDocument CanClose="False" CanFloat="False"  ContentId="doc1" FloatingWidth="100">
                            <StackPanel>
                            <Frame BorderThickness="2" NavigationUIVisibility="Hidden"   x:Name="Mainframe" Source="{Binding DisplayPage, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />

                            </StackPanel>
                        </avalonDock:LayoutDocument>
                    </avalonDock:LayoutDocumentPane>

您好，我尝试了上述解决方案，但对我无效。
