文字框样式 [英] Text box styling

问题描述

每当我尝试将样式应用于文本框时，该样式都将对用户输入无响应.您能告诉我一种解决方法吗?这是我正在使用的xaml代码:

Whenever I try to apply a style to a textbox, it becomes unresponsive to user input. Can you tell me a way to solve this?Here is the xaml code I am using:

<Style x:Key="textbox"
       TargetType="TextBox">
  <Setter Property="OverridesDefaultStyle"
          Value="True" />
  <Setter Property="Template">
    <Setter.Value>
      <ControlTemplate TargetType="TextBox">
        <Border BorderThickness="3"
                Background="{TemplateBinding Background}"
                Name="border">
          <ContentPresenter HorizontalAlignment="Center"
                            VerticalAlignment="Center" />
        </Border>
        <ControlTemplate.Triggers>
          <Trigger Property="IsMouseOver"
                   Value="True">
            <Setter TargetName="border"
                    Property="BorderBrush"
                    Value="#9E5971" />
          </Trigger>
        </ControlTemplate.Triggers>
      </ControlTemplate>
    </Setter.Value>
  </Setter>
</Style>

推荐答案

替换

<ContentPresenter
    HorizontalAlignment="Center" VerticalAlignment="Center" />

使用

<ScrollViewer
    x:Name="PART_ContentHost"
    SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>

名为 PART_ContentHost 的

ScrollViewer 是任何 TextBox 控件模板的必需部分.您应该使用默认WPF控件样式和模板作为参考，而不是提出来使用您自己的模板.

ScrollViewer named PART_ContentHost is a mandatory part of any TextBox control template. You should use Default WPF Control Styles and Templates as reference instead of coming up with your own template.
