WPF TABSTOP文本框不起作用Win10

Question

我正在努力测试我的WPF应用程序，其中我有一个带有文本框的窗口，该窗口包含来自应用程序的自定义样式。Resources.resources

样式实现了占位符，并且因为它干扰了表（它以占位符而不是TB内容为重点），所以我不得不添加一些ISTABSTOP代码。

当IM调试和Win7上的版本EXE时，它的工作正常很好，但是Tabbing在Win10上不起作用，它只是忽略了文本框，而只是Tabs worts worts其他没有实现此样式的控件。

任何帮助都很好！

这是样式代码：

<Style x:Key="placeHolderNoline" TargetType="{x:Type TextBox}" BasedOn="{StaticResource tb}">
            <Setter Property="IsTabStop" Value="False"/>
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type TextBox}">

                        <Grid>
                            <TextBox Text="{Binding Path=Text,
                                            RelativeSource={RelativeSource TemplatedParent}, 
                                            Mode=TwoWay,
                                            UpdateSourceTrigger=PropertyChanged}"
                             x:Name="textSource" 
                             Background="Transparent" 
                             Panel.ZIndex="2" 
                                 BorderThickness="0,0,0,0"/>

                            <TextBox Text="{TemplateBinding Tag}" Background="{TemplateBinding Background}" Panel.ZIndex="1" BorderThickness="0" IsTabStop="False">
                                <TextBox.Style>
                                    <Style TargetType="{x:Type TextBox}">
                                        <Setter Property="Foreground" Value="Transparent"/>
                                        <Style.Triggers>
                                            <DataTrigger Binding="{Binding Path=Text, Source={x:Reference textSource}}" Value="">
                                                <Setter Property="Foreground" Value="LightGray"/>
                                            </DataTrigger>
                                        </Style.Triggers>
                                    </Style>
                                </TextBox.Style>
                            </TextBox>
                        </Grid>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>

编辑：TB样式：

 <Style TargetType="TextBox" x:Key="tb">
            <Setter Property="Foreground" Value="WhiteSmoke"/>
            <Setter Property="Background" Value="#33FFFFFF"/>
            <Setter Property="BorderThickness" Value="0"/>
        </Style>

TextBox的ControlTemplate不应该包括其他或两个其他TextBox元素。

尝试这种样式：

<Style x:Key="placeHolderNoline" TargetType="TextBox" BasedOn="{StaticResource tb}">
    <Setter Property="Background" Value="{DynamicResource {x:Static SystemColors.WindowBrushKey}}"/>
    <Setter Property="BorderBrush" Value="#FFABAdB3"/>
    <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type TextBox}">
                <Border x:Name="border" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" SnapsToDevicePixels="True">
                    <Grid>
                        <TextBlock Text="{TemplateBinding Tag}" Foreground="LightGray" Background="{TemplateBinding Background}">
                            <TextBlock.Style>
                                <Style TargetType="{x:Type TextBlock}">
                                    <Setter Property="Visibility" Value="Collapsed"/>
                                    <Style.Triggers>
                                        <DataTrigger Binding="{Binding Path=Text, RelativeSource={RelativeSource AncestorType=TextBox}}" Value="">
                                            <Setter Property="Visibility" Value="Visible"/>
                                        </DataTrigger>
                                    </Style.Triggers>
                                </Style>
                            </TextBlock.Style>
                        </TextBlock>
                        <ScrollViewer x:Name="PART_ContentHost" Focusable="false" HorizontalScrollBarVisibility="Hidden" VerticalScrollBarVisibility="Hidden"/>
                    </Grid>
                </Border>
                <ControlTemplate.Triggers>
                    <Trigger Property="IsEnabled" Value="false">
                        <Setter Property="Opacity" TargetName="border" Value="0.56"/>
                    </Trigger>
                    <Trigger Property="IsMouseOver" Value="true">
                        <Setter Property="BorderBrush" TargetName="border" Value="#FF7EB4EA"/>
                    </Trigger>
                    <Trigger Property="IsKeyboardFocused" Value="true">
                        <Setter Property="BorderBrush" TargetName="border" Value="#FF569DE5"/>
                    </Trigger>
                </ControlTemplate.Triggers>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>
