WPF：通过 Tab 键浏览 Treeview 中用户控件中的文本框
WPF: Tab through textboxes in user controls in a Treeview
我正在尝试在我的应用程序中实现 Tab 功能，但我似乎没有任何尝试，所以我想我只是不明白它的用途。
我有一个用户控件（我们称它为 MyControl），其中包含一个文本框（以及其他内容）。 MyControl 与树视图一起使用。对于用户来说它看起来像这样（+ 号显示整个用户控件，以及子 MyControl 如果有的话，红色箭头显示预期的 Tab 行为）：
在 MyControl 中，我已将除 TextBox 之外的所有控件的 IsTabStop 设置为 false，我几乎已将我的整个应用程序设置为 IsTabStop = false。我已经尝试在 MyControl 和 TreeView 以及包含 TreeView 的页面和 window 上将 KeyboardNavigation.TabNavigation 设置为“循环”和“继续”。我尝试了不同的组合（在 treeview 上循环，在 mycontrol 上继续，反之亦然，等等）。
我还尝试将 TabIndex 设置为与创建 MyControl 对象的顺序相同。 （因此，第一个获得 1，第二个获得 2，依此类推）。
但是我尝试过的任何东西（在所有不同的组合中）都没有让选项卡进入我希望它进入的文本框。所以我的问题不仅是顺序错误，它只是选择了“treeview”，在它周围制作了一个虚线方块。如果我更改一些设置，焦点就会乱七八糟地转到随机元素，但永远不会转到文本框
所以，我做错了什么？ Tab 应该如何实现？
不知道要显示什么代码，但是：
我的控件：
<UserControl x:Class="SinusManager.View.ParamNodeV"
//blaablaa
x:Name="pn"
KeyboardNavigation.TabNavigation="Continue"
IsTabStop="True">
//blaablaa
<StackPanel Background="{StaticResource Milky} KeyboardNavigation.TabNavigation="Continue">
<Grid>
//blaablaa
<TextBox x:Name="ValueBox" VerticalContentAlignment="Center" PreviewTextInput="NumberValidationTextBox" FontFamily="{StaticResource MonoFont}" Text="{Binding Path=ValueText, ElementName=pn, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" HorizontalAlignment="Left" Margin="130,0,0,0" VerticalAlignment="Top" Height="26" Width="92"
IsTabStop="True" KeyboardNavigation.TabNavigation="Continue" IsReadOnly="{Binding Path=ReadOnly, ElementName=pn}">
//blaablaa
TreeView 用户控件
<UserControl x:Class="SinusManager.View.ParamFrameV"
//blaablaa
x:Name="pf"
KeyboardNavigation.TabNavigation="Cycle">
<Grid>
<ScrollViewer VerticalScrollBarVisibility="Visible" HorizontalScrollBarVisibility="Disabled" Margin="0,0,0,0">
<i:Interaction.Behaviors>
<v:BubbleScrollEvent/>
</i:Interaction.Behaviors>
//blaablaa
<TreeView Margin="0,16,0,0" KeyboardNavigation.TabNavigation="Cycle" ItemsSource="{Binding Nodes}" Background="{StaticResource Milky}" BorderThickness="0" ItemContainerStyle="{StaticResource TreeViewItemExpandedStyle}" HorizontalAlignment="Left" ScrollViewer.HorizontalScrollBarVisibility="Disabled" ScrollViewer.VerticalScrollBarVisibility="Disabled">
<TreeView.Resources>
<HierarchicalDataTemplate DataType="{x:Type vm:ParamTextNodeVM}" ItemsSource="{Binding Path=Nodes}">
<v:ParamNodeV Node="{Binding Path=NodeM}" Status="{Binding Status, Mode=TwoWay}" IsTabStop="True" NameText="{Binding Path=Name}" UnitText="{Binding Path=Unit}" ValueText="{Binding Path=Value, Mode=TwoWay}" RangeText="{Binding Path=Range}" ValueTypeText="{Binding Path=ValueType}" DescriptionText="{Binding Path=Description}" ReadOnly="{Binding Path=ReadOnly}" GetParameter="{Binding GetParameterCmd}" SendParameter="{Binding SendParameterCmd}"/>
</HierarchicalDataTemplate>
//blaablaa
上面的代码没有我尝试过的 TabOrder 绑定，我删除了它，因为它不起作用。但基本上我有一个整数，它为每个创建并添加到 TreeView 的新 MyControl 计数，并使用该整数在控件上设置 TabIndex。不，使用或不使用 TabOrder 的行为有所不同（是的，绑定有效）。
编辑：
仍然没有回答，我想我会在这里转储所有代码，也许有人会发现一些东西，我真的很想解决这个问题。
