每当我尝试将样式应用于文本框时，它都会对用户输入无响应。你能告诉我解决这个问题的方法吗？这是我正在使用的 xaml 代码：
<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>

Replace
代替
<ContentPresenter
HorizontalAlignment="Center" VerticalAlignment="Center" />
with
和
<ScrollViewer
x:Name="PART_ContentHost"
SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
ScrollViewernamed PART_ContentHostis a mandatory part of any TextBoxcontrol template. You should use Default WPF Control Styles and Templatesas reference instead of coming up with your own template.
ScrollViewernamedPART_ContentHost是任何TextBox控制模板的必需部分。您应该使用默认 WPF 控件样式和模板作为参考，而不是想出您自己的模板。
