Question

如何创建一个混合到背景页面的文本框，这里的想法是我想在线上创建像线条和用户类型一样的NoteBook（就像在带有线条的笔记本中写一样）。

Answer 1

取一个透明背景的TextBox，将其放在笔记本纸张图像的顶部，并根据需要调整字体大小。您可能希望使用TextBox

打包ViewBox

 <TextBox TextWrapping="Wrap" Background="{x:Null}"/>

或者使用带有笔记本纸张图像的TextBox作为背景：

 <TextBox TextWrapping="Wrap">
    <TextBox.Background>
       <ImageBrush ImageSource="notebook-paper.png"/>
    </TextBox.Background>
 </TextBox>

Answer 2

根据需要设置TextBox的样式，以便显示背景。要删除文本框的背景，填充，边框等，请使用：

<TextBox Margin="0" BorderThickness="0" Padding="0" Background="Transparent" />

要控制线条高度以使其在记事本线条图形上整齐排列，请使用TextBlock附加属性：

<TextBox
    Margin="0" BorderThickness="0" Padding="0" Background="Transparent"
    TextBlock.LineHeight="10" 
    TextBlock.LineStackingStrategy="BlockLineHeight" />

Answer 3

有一种更好的方法可以做到这一点。您可以覆盖默认样式并使TextBox透明。就像那样。

<TextBox Style="{StaticResource TransparentTextBox}"/>

这是那种风格：

<Style x:Key="TransparentTextBox" TargetType="TextBox">
        <Setter Property="FontFamily" Value="{StaticResource PhoneFontFamilyNormal}"/>
        <Setter Property="FontSize" Value="{StaticResource PhoneFontSizeMediumLarge}"/>
        <Setter Property="Background" Value="{StaticResource PhoneTextBoxBrush}"/>
        <Setter Property="Foreground" Value="{StaticResource PhoneTextBoxForegroundBrush}"/>
        <Setter Property="BorderBrush" Value="{StaticResource PhoneTextBoxBrush}"/>
        <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">
