WPF - 如何跳过选项卡导航中的标签？

Question

我在用户控件内的网格​​内的堆栈面板内的项目控件内的控件模板内有一个堆栈面板(请参见下面的 xaml)。在内部堆栈面板中有一个标签 (Name="NoComponentChosen") 和另一个堆栈面板 (Name="ComponentChosen")。标签的可见性最初是折叠的。

controltemplate 有一个带有绑定(bind)的数据触发器。当绑定(bind)引用具有特定值时，标签 (NoComponentChosen) 变为可见并且堆栈面板折叠。

当我在用户界面中切换时，我想跳过标签/堆栈面板。我还希望仍然能够通过 tab 浏览我的 ChangeRequestView.xaml(列表框和按钮)中的其余内容。

现在 - 当我点击 - 标签/堆栈面板最终被选中并被一个虚线矩形包围。这是我想避免的。

这是我的 ChangeRequestView.xaml:

<UserControl x:Class="MyProgram.View.ChangeRequestView"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

             xmlns:ListBoxBehavior="clr-namespace:MyProgram.Utility"
             mc:Ignorable="d" 
             d:DesignHeight="500" d:DesignWidth="300">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="50"/>
            <RowDefinition Height="35"/>
            <RowDefinition Height="45*"/>
            <RowDefinition Height="10*"/>
            <RowDefinition Height="20*"/>
            <RowDefinition Height="35"/>
        </Grid.RowDefinitions>

        <!--The title of the view-->
        <Label Grid.Row="0" Content="Change Requests" FontWeight="Bold" Margin="5,5,5,5" VerticalAlignment="Center" HorizontalAlignment="Center"/>

        <!--The component chosen-->
        <StackPanel Grid.Row="1" Orientation="Horizontal" Margin="5,0,0,0" IsHitTestVisible="False" Focusable="False">
            <ItemsControl>
                <ItemsControl.Template>
                    <ControlTemplate>
                        <StackPanel>
                            <StackPanel Name="ComponentChosen" Orientation="Horizontal">
                                <Label Content="Reference des.: " />
                                <Label Name="referenceDesignation" Content="{Binding Path=ReferenceDesignation, UpdateSourceTrigger=PropertyChanged}"/>
                            </StackPanel>
                            <Label Name="NoComponentChosen" Content="Choose a component" Visibility="Collapsed"/>
                        </StackPanel>
                        <ControlTemplate.Triggers>
                            <DataTrigger Binding="{Binding ReferenceDesignation}" Value="">
                                <Setter TargetName="ComponentChosen" Property="Visibility" Value="Collapsed"/>
                                <Setter TargetName="NoComponentChosen" Property="Visibility" Value="Visible"/>
                            </DataTrigger>
                        </ControlTemplate.Triggers>
                    </ControlTemplate>
                </ItemsControl.Template>
            </ItemsControl>
        </StackPanel>

        <ListBox Grid.Row="2" ... />
        <Button Grid.Row="3" ... />
        <Button Grid.Row="4" ... />
    </Grid>
</UserControl> 

整个 UserControl/ChangeRequestView.xaml 是我的 MainWindow 的一部分——我不知道这是否有什么要说的。我在 MainWindow 中浏览所有不同的 View ，当我到达 ChangeRequestView 时，我想根据其中哪些未折叠来跳过标签/堆栈面板。

这是我的 MainWindow.xaml:

<Window x:Class="MyProgram.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:view="clr-namespace:MyProgram.View"
        xmlns:vm="clr-namespace:MyProgram.ViewModel"
        ...>
    <Grid>
        <Grid.RowDefinitions>
        <RowDefinition Height="20"/>
        <RowDefinition Height="309*"/>
        <RowDefinition Height="187*"/>
        <RowDefinition Height="120*"/>
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="209*"/>
        <ColumnDefinition Width="558*"/>
        <ColumnDefinition Width="250*"/>
    </Grid.ColumnDefinitions>

    <Menu IsMainMenu="True" Name="Menu1" VerticalAlignment="Top" Grid.Row="0" Grid.ColumnSpan="3">
        <MenuItem Header="_File">
            <MenuItem Header="_Save changed change requests for current reference designation" 
                      InputGestureText="Ctrl+S" Command="{Binding Path=HotKeysSaveChangeRequestUpdateCmd}"/>
            <MenuItem Header="_Upload change requests for current project" 
                      InputGestureText="Ctrl+U" Command="{Binding Path=HotKeysUploadCmd}"/>
            <MenuItem Header="_Exit" ToolTip="Exit this program" 
                      InputGestureText="CTRL+X" Command="{Binding Path=ShutDownCmd}"/>
        </MenuItem>
    </Menu>

    <!--Search Region-->
    <Border Grid.Row="2" Grid.Column="0" Grid.RowSpan="2" Margin="3,1,1,3" BorderThickness="2,2,2,2" CornerRadius="4,4,4,4" BorderBrush="LightGray">

    </Border>

</Window> </br>

对于冗长的 xaml 文件，我深表歉意，但我认为我提供给您的信息越多，您就越容易帮助我解决这个标签问题。

当我在用户界面中切换时，您是否知道如何跳过标签“NoComponentChosen”/堆栈面板“ComponentChosen”？

尝试 KeyboardNavigation.TabNavigation Attached Property与 KeyboardNavigationMode.None在包含您要跳过的元素的容器上。

KeyboardNavigation.TabNavigation="None"
