由于Textbox直接使用是一条直线 设置如下代码 可以让Textbox变为直线输入
XML
<Style TargetType="TextBox"
x:Key="UsernameTextBoxStyle">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TextBox}">
<Border x:Name="border"
BorderBrush="#DDD"
BorderThickness="0,0,0,1"
Background="{TemplateBinding Background}"
SnapsToDevicePixels="True">
<Grid>
<TextBlock Text="账号/手机号/邮箱"
Grid.Column="1"
VerticalAlignment="Center"
Foreground="#DDD"
Name="markText"
Visibility="Collapsed"
FontSize="12"
Margin="2,0" />
<ScrollViewer x:Name="PART_ContentHost"
Focusable="false"
HorizontalScrollBarVisibility="Hidden"
VerticalScrollBarVisibility="Hidden"
Grid.Column="1"
VerticalAlignment="Center"
MinHeight="20" />
</Grid>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver"
Value="true">
<Setter Property="BorderBrush"
TargetName="border"
Value="#0b3d90" />
</Trigger>
<Trigger Property="IsKeyboardFocused"
Value="true">
<Setter Property="BorderBrush"
TargetName="border"
Value="#0b3d90" />
</Trigger>
<DataTrigger Binding="{Binding Path=Text,RelativeSource={RelativeSource Mode=Self}}"
Value="">
<Setter Property="Visibility"
TargetName="markText"
Value="Visible" />
</DataTrigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Textbox 采用上面的样式 即为
XML
<TextBox Width="90"
Height="20"
Text="{Binding PLCIP}"
Style="{StaticResource UsernameTextBoxStyle}"/>
结果如下:
