WPF表单中的箭头键导航是奇怪的

我有一个WPF的形式，我想有箭头键导航。当前系统已关闭，即使我已成功指定选项卡导航顺序。我有两排三个单选按钮。当我在中间按钮，最上面一行，我应该能够点击左箭头，并选择第一个按钮的最上面一行；相反，它选择第一个按钮，即底部的一行。我如何纠正这个问题

对我来说，这也是一种奇怪的行为，玩过之后，我可以告诉你这是由HorizontalAlignment属性引起的，但我无法解释原因。也许其他人可以解释一下

在您的案例中，控件按内容属性的字母顺序集中。您可以通过更改

<RadioButton Content="All People" Grid.Column="0" HorizontalAlignment="Left"

由于我没有意识到这种行为，我尝试通过使用以下XAML创建一个新项目来复制，但箭头键的行为与预期一样，将重点放在箭头键方向的下一个邻居上：

<Grid>
        <Grid.RowDefinitions>
            <RowDefinition></RowDefinition>
            <RowDefinition></RowDefinition>
        </Grid.RowDefinitions>

        <Grid Grid.Row="0">
            <Grid.RowDefinitions>
                <RowDefinition></RowDefinition>
            </Grid.RowDefinitions>
            <Grid.ColumnDefinitions>
                <ColumnDefinition></ColumnDefinition>
                <ColumnDefinition></ColumnDefinition>
                <ColumnDefinition></ColumnDefinition>
            </Grid.ColumnDefinitions>
            <RadioButton Grid.Column="0" Content="All People"></RadioButton>
            <RadioButton Grid.Column="1" Content="Users Only"></RadioButton>
            <RadioButton Grid.Column="2" Content="Admin Only"></RadioButton>
        </Grid>

        <Grid Grid.Row="1">
            <Grid.RowDefinitions>
                <RowDefinition></RowDefinition>
            </Grid.RowDefinitions>
            <Grid.ColumnDefinitions>
                <ColumnDefinition></ColumnDefinition>
                <ColumnDefinition></ColumnDefinition>
                <ColumnDefinition></ColumnDefinition>
            </Grid.ColumnDefinitions>
            <RadioButton Grid.Column="0" Content="Off Campus"></RadioButton>
            <RadioButton Grid.Column="1" Content="Admin"></RadioButton>
            <RadioButton Grid.Column="2" Content="User"></RadioButton>
        </Grid>
</Grid>



所以我删除了xaml单选按钮的属性，直到我最终通过删除HorizontalAlignment达到了目的

XAML现在正在按预期工作，至少对于单选按钮：

<Grid Grid.Column="1" Grid.Row="0">
    <Grid.ColumnDefinitions>
        <ColumnDefinition/>
        <ColumnDefinition/>
        <ColumnDefinition/>
    </Grid.ColumnDefinitions>
    <RadioButton Content="All People" Grid.Column="0" Margin="0,5,0,0" VerticalAlignment="Top" IsChecked="{Binding Path=IsPersonAll}" TabIndex="3" />
    <RadioButton Content="Users Only" Grid.Column="1" Margin="0,5,0,0" VerticalAlignment="Top" IsChecked="{Binding Path=IsPersonUser}" TabIndex="4" />
    <RadioButton Content="Admin Only" Grid.Column="2" Margin="0,5,0,0" VerticalAlignment="Top" TabIndex="5" />
</Grid>
<Grid Grid.Column="1" Grid.Row="1">
    <Grid.ColumnDefinitions>
        <ColumnDefinition/>
        <ColumnDefinition/>
        <ColumnDefinition/>
    </Grid.ColumnDefinitions>
    <RadioButton Content="Off Campus" Grid.Column="0" Margin="0,5,0,0" VerticalAlignment="Top" IsChecked="{Binding Path=IsCallerOff}" TabIndex="6" />
    <RadioButton Content="Admin" Grid.Column="1"  Margin="0,5,0,0" VerticalAlignment="Top" IsChecked="{Binding Path=IsCallerOnAd}" TabIndex="7" />
    <RadioButton Content="User" Grid.Column="2" Margin="0,5,0,0" VerticalAlignment="Top" TabIndex="8" />
</Grid>

Tabindex不应影响箭头键导航，而是通过布局容器的子级进行导航。您是否使用单个网格（2行/3列）承载单选按钮？也许可以提供XAML@milter--谢谢，这是密码。
<Grid Grid.Column="1" Grid.Row="0">
    <Grid.ColumnDefinitions>
        <ColumnDefinition/>
        <ColumnDefinition/>
        <ColumnDefinition/>
    </Grid.ColumnDefinitions>
    <RadioButton Content="All People" Grid.Column="0" Margin="0,5,0,0" VerticalAlignment="Top" IsChecked="{Binding Path=IsPersonAll}" TabIndex="3" />
    <RadioButton Content="Users Only" Grid.Column="1" Margin="0,5,0,0" VerticalAlignment="Top" IsChecked="{Binding Path=IsPersonUser}" TabIndex="4" />
    <RadioButton Content="Admin Only" Grid.Column="2" Margin="0,5,0,0" VerticalAlignment="Top" TabIndex="5" />
</Grid>
<Grid Grid.Column="1" Grid.Row="1">
    <Grid.ColumnDefinitions>
        <ColumnDefinition/>
        <ColumnDefinition/>
        <ColumnDefinition/>
    </Grid.ColumnDefinitions>
    <RadioButton Content="Off Campus" Grid.Column="0" Margin="0,5,0,0" VerticalAlignment="Top" IsChecked="{Binding Path=IsCallerOff}" TabIndex="6" />
    <RadioButton Content="Admin" Grid.Column="1"  Margin="0,5,0,0" VerticalAlignment="Top" IsChecked="{Binding Path=IsCallerOnAd}" TabIndex="7" />
    <RadioButton Content="User" Grid.Column="2" Margin="0,5,0,0" VerticalAlignment="Top" TabIndex="8" />
</Grid>
