【WPF】TextBox样式重写注意事项

1、普通控件重写需要添加一行

 <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"  Margin="{TemplateBinding Padding}"></ContentPresenter>

2、TextBox之类的编辑控件重写,需要填加一行

 <ScrollViewer x:Name="PART_ContentHost"></ScrollViewer>

只有这样才能进入编辑模式

举个栗子:

<ControlTemplate x:Key="RoundTextBoxTemplate" TargetType="TextBox">
<Border CornerRadius="5" BorderBrush="LightSkyBlue" BorderThickness="2" Background="{TemplateBinding Background}" Margin="3">
<ScrollViewer x:Name="PART_ContentHost"></ScrollViewer>
</Border>
</ControlTemplate> <Style x:Key="RoundTextBoxStyle" TargetType="TextBox">
<Setter Property="Template" Value="{DynamicResource ResourceKey=RoundTextBoxTemplate}" ></Setter>
</Style>

上面就是实现最简单的TextBox重写样式的功能了
