Question

问题是，当我想在文本框中写东西时，我无法专注于它。谢谢合作:)

<!--LayoutRoot is the root grid where all page content is placed-->
<Grid x:Name="LayoutRoot" Background="Transparent">
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="*"/>
    </Grid.RowDefinitions>
                <!--TitlePanel contains the name of the application and page title-->
        <StackPanel x:Name="TitlePanel" Grid.Row="0" Margin="12,17,0,28">
            <TextBlock x:Name="ApplicationTitle" Text="MY APPLICATION" Style="{StaticResource PhoneTextNormalStyle}"/>
            <TextBlock x:Name="PageTitle" Text="Hello Phone" Margin="9,-7,0,0" Style="{StaticResource PhoneTextTitle1Style}"/>
        </StackPanel>

        <!--ContentPanel - place additional content here-->
        <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="*" />
                <ColumnDefinition Width="Auto"/>
            </Grid.ColumnDefinitions>
            <TextBox Grid.Column="0" Name="MessageTextBox" 
                 FontSize="{StaticResource PhoneFontSizeExtraLarge}" Margin="20,20,10,20" />
            <Button Grid.Column="1" Name="ClickMeButton" Content="Click Me" 
                HorizontalAlignment="Right" Padding="4" Margin="10,20,20,20" Click="ClickMeButton_Click" />
        <Grid Grid.Row="2">

尝试将属性“IsEnabled”显式设置为true。

编辑：我实际上尝试过它看起来不像它有效。奇怪的是，如果你从后面的代码中调用 Focus（）就可以了。

编辑：搞清楚了！您需要在网格上设置正确的“RowDefintions”。看看这段代码：

<!--TitlePanel contains the name of the application and page title-->
<Grid x:Name="LayoutRoot" Background="Transparent">
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="*"/>
    </Grid.RowDefinitions>
    <!--TitlePanel contains the name of the application and page title-->
    <StackPanel x:Name="TitlePanel" Grid.Row="0" Margin="12,17,0,28">
        <TextBlock x:Name="ApplicationTitle" Text="MY APPLICATION" Style="{StaticResource PhoneTextNormalStyle}"/>
        <TextBlock x:Name="PageTitle" Text="Hello Phone" Margin="9,-7,0,0" Style="{StaticResource PhoneTextTitle1Style}"/>
    </StackPanel>
    <!--ContentPanel - place additional content here-->
    <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
        <Grid.RowDefinitions>
            <RowDefinition/>
            <RowDefinition/>
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="*" />
            <ColumnDefinition Width="Auto"/>
        </Grid.ColumnDefinitions>
        <TextBox Grid.Row="0" Grid.Column="0" Name="MessageTextBox" Margin="20,20,10,20" IsEnabled="True" />
        <Button Grid.Row="0" Grid.Column="1" Name="ClickMeButton" Content="Click Me" HorizontalAlignment="Right" Padding="4" Margin="10,20,20,20" Click="ClickMeButton_Click" IsEnabled="True" />
        <Grid Grid.Row="1">
            <TextBlock Name="BannerTextBlock" Style="{StaticResource PhoneTextExtraLargeStyle}"            Foreground="#FFFF7A00" HorizontalAlignment="Stretch"           TextWrapping="Wrap" TextAlignment="Center" FontWeight="Bold" />
        </Grid>
    </Grid>
</Grid>

为什么我的代码不应该工作呢？
