您需要定义自定义ControlTemplate
:
<TextBox x:Name="txbUsername" VerticalAlignment="Center" HorizontalAlignment="Center"
Width="350" Height="20" Margin="5 0 0 0" BorderThickness="0 0 0 1" Background="#eff0f1">
<TextBox.Style>
<Style TargetType="{x:Type TextBox}">
<Setter Property="FontSize" Value="14"></Setter>
<Setter Property="FontFamily" Value="Verdana, Geneva, sans-serif"></Setter>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TextBox}">
<Border x:Name="border" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" SnapsToDevicePixels="True">
<ScrollViewer x:Name="PART_ContentHost" Focusable="false" HorizontalScrollBarVisibility="Hidden" VerticalScrollBarVisibility="Hidden"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsEnabled" Value="false">
<Setter Property="Opacity" TargetName="border" Value="0.56"/>
</Trigger>
<Trigger Property="IsKeyboardFocused" Value="true">
<Setter Property="BorderThickness" Value="0 0 0 1"></Setter>
<Setter Property="BorderBrush" Value="#a70711"></Setter>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</TextBox.Style>
</TextBox>
原因是默认ControlTemplate
中定义的某些触发器无法通过简单地定义一些自定义Style
触发器来覆盖。
