c# - 在 windows phone 7 中突出显示文本框/文本块

Question

我正在开发一个应用程序，我要求用户在 windows phone 7 中突出显示一些文本。我想使用一个文本框（它提供突出显示），但只要我点击它，就会打开一个键盘。我只需要突出显示。如果我使IsReadOnly属性为真，那么它是灰色的。我该怎么做？还有如何使用文本块？

做这样的事情怎么样？

<TextBox Text="Select me, I'm a TextBox" 
            TextWrapping="Wrap" 
            IsReadOnly="True" 
            Style="{StaticResource TextBoxStyle1}" />

它看起来像一个 TextBlock，但在可以选择但不拉出键盘的意义上，它的行为就像一个 TextBox。

TextBoxStyle1 是这种风格：

<Style x:Key="TextBoxStyle1" TargetType="TextBox">
    <Setter Property="FontFamily" Value="{StaticResource PhoneFontFamilyNormal}"/>
    <Setter Property="FontSize" Value="{StaticResource PhoneFontSizeMediumLarge}"/>
    <Setter Property="Background" Value="{StaticResource PhoneBackgroundBrush}"/>
    <Setter Property="Foreground" Value="{StaticResource PhoneForegroundBrush}"/>
    <Setter Property="BorderBrush" Value="{StaticResource PhoneBackgroundBrush}"/>
    <Setter Property="SelectionBackground" Value="{StaticResource PhoneAccentBrush}"/>
    <Setter Property="SelectionForeground" Value="{StaticResource PhoneTextBoxSelectionForegroundBrush}"/>
    <Setter Property="BorderThickness" Value="{StaticResource PhoneBorderThickness}"/>
    <Setter Property="Padding" Value="2"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="TextBox">
                <Grid Background="Transparent">
                    <VisualStateManager.VisualStateGroups>
                        <VisualStateGroup x:Name="CommonStates">
                            <VisualState x:Name="Normal"/>
                            <VisualState x:Name="MouseOver"/>
                            <VisualState x:Name="Disabled">

看起来像这样：
