[UWP] [XAML]不显示文本框内容

时间：2018-10-15 13:58:00

标签： c# xaml uwp

在发布此问题之前，我已经搜索并研究了关于StackOverflow的所有答案，但没有一个对我有帮助，所以我在这里^^

我的目标是使用TextBox在UWP中获得标签的对应性。

  • 在TextBox属性中，我设置了“ IsReadOnly =“ True”“，但是即使“ box”的属性设置为“透明”，也仍然可见。

  • 所以我还添加了“ IsEnabled =“ False”“属性，并获得了“标签”。

但是，由于项目需求，我需要白色文本，而不是uwp的默认灰色文本。因此，我一直尝试设置自定义样式（遵循stackOverflow的所有答案），直到找到以下解决方案为止：

 <Style x:Key="Titoli" TargetType="TextBox">
            <Setter Property="MinWidth" Value="{ThemeResource TextControlThemeMinWidth}" />
            <Setter Property="MinHeight" Value="{ThemeResource TextControlThemeMinHeight}" />
            <Setter Property="Foreground" Value="White" />
            <Setter Property="Background" Value="Transparent" />
            <Setter Property="BorderBrush" Value="Transparent" />
            <Setter Property="SelectionHighlightColor" Value="{ThemeResource SystemControlHighlightAccentBrush}" />
            <Setter Property="BorderThickness" Value="{ThemeResource TextControlBorderThemeThickness}" />
            <Setter Property="FontFamily" Value="{ThemeResource ContentControlThemeFontFamily}" />
            <Setter Property="FontSize" Value="{ThemeResource ControlContentThemeFontSize}" />
            <Setter Property="ScrollViewer.HorizontalScrollMode" Value="Auto" />
            <Setter Property="ScrollViewer.VerticalScrollMode" Value="Auto" />
            <Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Hidden" />
            <Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="Hidden" />
            <Setter Property="ScrollViewer.IsDeferredScrollingEnabled" Value="False" />
            <Setter Property="Padding" Value="{ThemeResource TextControlThemePadding}"/>
            <Setter Property="IsReadOnly" Value="True"  />
            <Setter Property="Background" Value="{x:Null}" />
            <Setter Property="IsHitTestVisible"  Value="False"  />

            <Setter Property="Template" >
                <Setter.Value>
                    <ControlTemplate TargetType="TextBox">
                        <Border x:Name="ContentElement" />
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>

并获得此预览（T1，T2，T3 ecc是我正在关注的标签）：

但是当我调试时，该应用具有以下外观：

Debug

因此，没有“打印”出任何文本框...我真的不知道解决方案（我的自定义bottons图像也消失了！）有什么建议吗？

我还从here复制并粘贴了完整的TextBox，并进行了修改，但是我无法以这种方式在第一个屏幕中检索解决方案...

Xaml.MainPage的

好吧，在@touseefbsb之后，我设法找到了解决方法。

在Stackpanels中进行组织，并使用Stretch =“ Uniform”中的ViewBox调整视图，这是我所获得的：

<Viewbox Stretch="Uniform">
<Grid  >

    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="2*"/>
        <ColumnDefinition Width="3*"/>

    </Grid.ColumnDefinitions>

    <Grid.RowDefinitions>
        <RowDefinition Height="2*"/>
        <RowDefinition Height="*"/>
        <RowDefinition Height="*"/>
    </Grid.RowDefinitions>

    <!-- Sezione Segnali -->
    <StackPanel>
        <GridView>
            ....
        </GridView>

    </StackPanel>

    <!-- Sezione Display temperature -->
    <StackPanel Grid.Column="1">

        <GridView>
            <TextBlock x:Name="Sonda_1" TextWrapping="WrapWholeWords" Margin="90 91 -90 10"  FontSize="120" FontFamily="Segoi UI" Foreground="White" Width="200"  Height="120" />
            <TextBlock Text="T1 °C" TextWrapping="WrapWholeWords" Margin="100 100 45 10"  FontSize="50" FontFamily="Segoi UI" Foreground="White" Width="55"  Height="120" />
            <TextBlock x:Name="Sonda_2" TextWrapping="WrapWholeWords" Margin="90 91 -90 10"  FontSize="120" FontFamily="Segoi UI" Foreground="White" Width="200"  Height="120" />
            <TextBlock Text="T2 °C" TextWrapping="WrapWholeWords" Margin="100 100 45 10"  FontSize="50" FontFamily="Segoi UI" Foreground="White" Width="55"  Height="120" />
        </GridView>
        <GridView>

        </GridView>

    </StackPanel>

    <!-- Sezione Pulsanti -->
    <StackPanel  Grid.Row="1">
        <GridView>
           ...

        </GridView>

    </StackPanel>
    <StackPanel Grid.Column="1" Grid.Row="1">
        <GridView>

            ....

        </GridView>

    </StackPanel>


    <!-- Sezione Loghi -->
    <StackPanel Grid.Row="2">
        ...
    </StackPanel>
    <StackPanel Grid.Row="2" Grid.Column="1">

       ...

    </StackPanel>

</Grid>
</Viewbox>

希望这会有所帮助：）
