Question

我有一个带有一些文本块和按钮的应用程序，我正在尝试加载TextBlock，它隐藏整个网格，然后根据我的可见性绑定再次显示它。问题是，加载文本消失了，但主网格遮蔽了所有按钮和东西后面的网格。有没有办法正确地做到这一点？

注意：如果没有加载TextBlock，只需一个隐藏/显示我的应用程序的矩形即可正常工作。

我的代码如下所示：

<Grid Margin="2" Background="Black">

<Border BorderThickness="2" BorderBrush="Black">
    <TextBlock HorizontalAlignment="Center" VerticalAlignment="Center" Text="LOADING..." Visibility="{Binding DownloadingWeather, Converter={StaticResource boolToVisibilityConverter}, ConverterParameter=False}" FontSize="20" Foreground="White">

    <Grid Visibility="{Binding DownloadingWeather, Converter={StaticResource boolToVisibilityConverter}, ConverterParameter=True}">
        <Grid.Background>
            <LinearGradientBrush StartPoint="0.5,0" EndPoint="0.5,1">
                <GradientStop Color="Gray" Offset="0.0" />
                <GradientStop Color="Black" Offset="0.5" />
                <GradientStop Color="Black" Offset="0.7" />
                <GradientStop Color="Gray" Offset="1.0" />
            </LinearGradientBrush>
        </Grid.Background>

        <Grid Grid.Row="4">
            <Grid.ColumnDefinitions>
                <ColumnDefinition />
                <ColumnDefinition />
            </Grid.ColumnDefinitions>
            <!-- Some Stuff like buttons and textblocks here-->

        </Grid>

        <Grid.RowDefinitions>
            <RowDefinition Height="3*" />
            <RowDefinition Height="*" />
            <RowDefinition Height="*" />
            <RowDefinition Height="*" />
            <RowDefinition Height="*" />
        </Grid.RowDefinitions>

        <!-- Some Stuff like buttons and textblocks here-->

    </Grid>
    </TextBlock>
</Border>
</Grid>

目前Grid是TextBlock的一部分。由于Border只能生一个孩子，因此您需要创建一个Grid，同时包含您想要显示的Text和Grid

<Border>
    <Grid>
        <TextBlock ... Text="LOADING..." Visibility="{Binding DownloadingWeather, Converter={StaticResource boolToVisibilityConverter}, ConverterParameter=False}"/>
        <Grid Visibility="{Binding DownloadingWeather, Converter={StaticResource boolToVisibilityConverter}, ConverterParameter=True}">
            <!-- Grid content -->
        </Grid>
    </Grid>
</Border>
