wpf ToggleButton选中效果和一个登录界面

先看效果

 

我修改了ToggleButton的ControlTemplate,在ContentPresenter外面加了4个Border,控制4个Border的位置在ControlTemplate的左上、右上、左下、右下,选中时,触发4个边框的BorderThickness
<Setter Property=”BorderThickness” TargetName=”brdOut1″ Value=”2,2,0,0″/>
<Setter Property=”BorderThickness” TargetName=”brdOut2″ Value=”0 2 2 0″/>
<Setter Property=”BorderThickness” TargetName=”brdOut3″ Value=”2 0 0 2″/>
<Setter Property=”BorderThickness” TargetName=”brdOut4″ Value=”0 0 2 2″/>

<Style   TargetType="{x:Type ToggleButton}"> 
        <Setter Property="Background" Value="Transparent"/>
        <Setter Property="BorderBrush" Value="DarkGray"/> 
        <Setter Property="BorderThickness" Value="1"/> 
        <Setter Property="Padding" Value="0"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type ToggleButton}">
                    <Grid>
                        <Border x:Name="brdOut1"  BorderBrush="{StaticResource MaterialDesignGroupBorder}" Width="20" Height="20" HorizontalAlignment="Left" VerticalAlignment="Top"/>
                        <Border x:Name="brdOut2" BorderBrush="{StaticResource MaterialDesignGroupBorder}" Width="20" Height="20" HorizontalAlignment="Right" VerticalAlignment="Top"/>
                        <Border x:Name="brdOut3" BorderBrush="{StaticResource MaterialDesignGroupBorder}" Width="20" Height="20" HorizontalAlignment="Left" VerticalAlignment="Bottom"/>
                        <Border x:Name="brdOut4" BorderBrush="{StaticResource MaterialDesignGroupBorder}" Width="20" Height="20" HorizontalAlignment="Right" VerticalAlignment="Bottom"/>
 
                        <Border Margin="2" x:Name="border" BorderBrush="{TemplateBinding BorderBrush}" CornerRadius="0" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" SnapsToDevicePixels="True">

                          <ContentPresenter Grid.Row="1" x:Name="contentPresenter" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" ContentStringFormat="{TemplateBinding ContentStringFormat}" Focusable="False" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/> 
                         </Border>
                    </Grid>
                    <ControlTemplate.Triggers>
                       
                        <Trigger Property="IsChecked" Value="True">
                            <Setter Property="BorderThickness" TargetName="brdOut1" Value="2,2,0,0"/>
                            <Setter Property="BorderThickness" TargetName="brdOut2" Value="0 2 2 0"/>
                            <Setter Property="BorderThickness" TargetName="brdOut3" Value="2 0 0 2"/>
                            <Setter Property="BorderThickness" TargetName="brdOut4" Value="0 0 2 2"/>

                        </Trigger>
                       
                        </DataTrigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

 

登录界面

之前看过一个html的登录界面效果挺好,就用wpf实现了一个

 

我是用的一个蓝色的圆,移动了圆的位置,在登录界面白色背景上形成了一个弧形划分的效果;当然也可以用背景图,但是我也没找到类似的图;这样做还有个好处,可以根据系统主题,变换登录界面弧形颜色。
右半部分的输入框部分代码我没贴。

<Window
      Loaded="Window_Loaded"   >
   
    <Grid> 
            <Ellipse Grid.Row="1" x:Name="blueQ" Stroke="Black"    Fill="#FF1C84EE"/> 
    </Grid>
</Window>
private void Window_Loaded(object sender, RoutedEventArgs e)
        {

            blueQ.Width = this.ActualHeight * 2;
            blueQ.Height = this.ActualHeight * 2;
            blueQ.Margin = new Thickness(-this.ActualHeight, -this.ActualHeight, 0, 0);
 
        }
