WPF一般是通过Style里的触发器来改变这些的,给你个完整的TextBox的Style,你再好好看下WPF教程里讲Style的部分

<Style TargetType="{x:Type TextBox}">
        <Setter Property="KeyboardNavigation.TabNavigation" Value="None" />
        <Setter Property="FocusVisualStyle" Value="{x:Null}" />
        <Setter Property="AllowDrop" Value="true" />
        <Setter Property="Background" >
            <Setter.Value>
                <SolidColorBrush Color="{DynamicResource WhiteColor}"/>
            </Setter.Value>
        </Setter>
        <Setter Property="HorizontalContentAlignment" Value="Stretch" />
        <Setter Property="VerticalContentAlignment" Value="Stretch" />
        <Setter Property="FontFamily" Value="Trebuchet MS" />
        <Setter Property="FontSize" Value="12" />
        <Setter Property="Padding" Value="4" />
        <Setter Property="BorderThickness" Value="1" />
        <Setter Property="BorderBrush" Value="{StaticResource TextControlBorderBrush}" />
<Setter Property="Template" Value="{DynamicResource TextBoxTemplate}" />
    </Style>
