效果：
xmal代码：
1 <Style x:Key="CheckBoxStyle" TargetType="{x:Type CheckBox}"> 2 <Setter Property="SnapsToDevicePixels" Value="true" /> 3 <Setter Property="OverridesDefaultStyle" Value="False" /> 4 <Setter Property="FocusVisualStyle" Value="{DynamicResource CheckBoxFocusVisual}" /> 5 <Setter Property="Height" Value="25"/> 6 <Setter Property="IsChecked" Value="False"/> 7 <Setter Property="Margin" Value="0,20"/> 8 <Setter Property="Template"> 9 <Setter.Value> 10 <ControlTemplate TargetType="CheckBox"> 11 <Grid> 12 <Grid.ColumnDefinitions> 13 <ColumnDefinition Width="Auto"/> 14 <ColumnDefinition Width="*"/> 15 </Grid.ColumnDefinitions> 16 <Grid Height="{TemplateBinding Height}" Width="{TemplateBinding Height}"> 17 <Rectangle x:Name="CheckBoxRectangle" Fill="LightSkyBlue" Opacity="0.3" RadiusY="5" RadiusX="5"/> 18 <Rectangle x:Name="CheckBoxRectangleOut" Stroke="#FF06DAD1" StrokeThickness="1" RadiusY="5" RadiusX="5"/> 19 <Grid x:Name="CheckedMark" Width="20" Height="20" Visibility="Collapsed"> 20 <Path SnapsToDevicePixels="False" StrokeThickness="3" Data="M1,9 L10,17" Stroke="White"/> 21 <Path SnapsToDevicePixels="False" StrokeThickness="3" Data="M8,17 L20,4" Stroke="White"/> 22 </Grid> 23 </Grid> 24 <TextBlock Grid.Column="1" Text="AAAA" FontSize="18" Foreground="White" VerticalAlignment="Center" Margin="14,0,0,0"/> 25 </Grid> 26 <ControlTemplate.Triggers> 27 <Trigger Property="IsChecked" Value="True"> 28 <Setter TargetName="CheckedMark" Property="Visibility" Value="Visible"></Setter> 29 <Setter TargetName="CheckBoxRectangle" Property="Fill" Value="#FF00A8E0"></Setter> 30 <Setter TargetName="CheckBoxRectangle" Property="Opacity" Value="1"></Setter> 31 <Setter TargetName="CheckBoxRectangleOut" Property="Stroke" Value="Transparent"></Setter> 32 </Trigger> 33 </ControlTemplate.Triggers> 34 </ControlTemplate> 35 </Setter.Value> 36 </Setter> 37 </Style>
加上动画的xaml代码
