Wpf 混合到背景中的文本框

如何创建一个融入背景页面的文本框，这里的想法是我想创建一个类似笔记本的效果，线条和用户类型在线条上（就像在笔记本中用线条书写一样）。

拿一个透明背景的

文本框

，将其放在笔记本纸图像的顶部，对齐字体大小，使其看起来符合要求。您可能需要使用

ViewBox

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

---

有一种更好的方法可以做到这一点。您只需覆盖默认样式并使文本框透明即可。像那样

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

以下是这种风格：

<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">

根据需要设置

文本框的样式，以便背景显示出来。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" />

如果你能用一行代码达到同样的效果，那么写81行代码会更好吗？；）@斯塔：同意。。。但我不敢相信你竟然费心数数这些行：）@HiTech Magic:Notepad++，ctrl-c，ctrl-v:）@StaWho:Revised。。。但我不敢相信，你竟然用Notepad++，ctrl-c，ctrl-v:>费劲地数数这些行，其中大部分是由Expression Blend生成的，这对于任何使用wpf/silverlight的人来说都是非常有用的工具。此外，这种方式封装了布局中的样式，这在控件由数百行代码组成时非常重要……并且去掉边框
BorderBrush=“{x:Null}”
或BorderThickness=“0”您确定
TextBlock.LineHeight
和
TextBlock.LineStackingStrategy
实际上是附加属性吗？Blend说，当我尝试您的示例时，它们“…只能应用于从TextBlock派生的类型”（即普通依赖属性）。VS2010还说，“在类型TextBlock中找不到附加的属性LineHeight”。。。您是否使用将这些作为附加属性的TextBlock扩展？如果是，请说明。
<TextBox Margin="0" BorderThickness="0" Padding="0" Background="Transparent" />

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