}

使用部分代码：

<c:NumericBox VerticalAlignment="Bottom" Width="200" BorderBrush="#ddd"BorderThickness="1" Margin="20"/>

UserControl与CustomControl区别

自定义控件：注重控件对象的功能，必须遵守WPF的控件规则

- 完全自己实现一个控件继承现有控件进行功能扩展，并且添加新功能 WPF的控件要求
- 后台代码（控制逻辑）和Generic.Xaml（样式模板）进行组合
- 支持模板重写
- 继承Control

用户控件：注重复合控件组合使用，非常灵活，可以根据控件开发人员自己的意愿进行功能处理

- 多个现有控件的集合，组成一个可复用的控件组
- XAML和后台代码组成绑定非常紧密
- 不支持模板重写、样式
- 继承UserControl

各种常见开关

自定义控件：代码：

<Style TargetType="{x:Type c:Switch}"><Setter Property="Template"><Setter.Value><ControlTemplate TargetType="{x:Type c:Switch}"><Grid><Border Width="{Binding RelativeSource={RelativeSource Self},Path=ActualHeight}" CornerRadius="{Binding RelativeSource={RelativeSource Self},Path=ActualHeight}"Visibility="Collapsed" Name="dropdown" Margin="-23"><Border.Background><RadialGradientBrush><GradientStop Color="Transparent" Offset="1"/><GradientStop Color="#5500D787" Offset="0.7"/><GradientStop Color="Transparent" Offset="0.59"/></RadialGradientBrush></Border.Background></Border><Border Width="{Binding RelativeSource={RelativeSource Self},Path=ActualHeight}"BorderBrush="DarkGreen" BorderThickness="5"CornerRadius="{Binding RelativeSource={RelativeSource Self},Path=ActualHeight}"Background="Gray" Name="bor"><Border Background="#FF00C88C" Margin="2" Name="bor1"Width="{Binding RelativeSource={RelativeSource Self},Path=ActualHeight}" CornerRadius="{Binding RelativeSource={RelativeSource Self},Path=ActualHeight}"/></Border></Grid><ControlTemplate.Triggers><Trigger Property="IsChecked" Value="True"><Trigger.EnterActions><BeginStoryboard><Storyboard ><ColorAnimation To="White" Duration="0:0:0.5"Storyboard.TargetName="bor1"Storyboard.TargetProperty="Background.Color"/><ColorAnimation To="#FF32FAC8" Duration="0:0:0.5"Storyboard.TargetName="bor"Storyboard.TargetProperty="BorderBrush.Color"/><ObjectAnimationUsingKeyFrames Storyboard.TargetName="dropdown"Storyboard.TargetProperty="Visibility"><DiscreteObjectKeyFrame KeyTime="0:0:0.3"><DiscreteObjectKeyFrame.Value><Visibility>Visible</Visibility></DiscreteObjectKeyFrame.Value></DiscreteObjectKeyFrame></ObjectAnimationUsingKeyFrames></Storyboard></BeginStoryboard></Trigger.EnterActions><Trigger.ExitActions><BeginStoryboard><Storyboard ><ColorAnimation Storyboard.TargetName="bor1"Storyboard.TargetProperty="Background.Color"/><ColorAnimation Storyboard.TargetName="bor"Storyboard.TargetProperty="BorderBrush.Color"/><ObjectAnimationUsingKeyFrames Storyboard.TargetName="dropdown"Storyboard.TargetProperty="Visibility"><DiscreteObjectKeyFrame KeyTime="0:0:0.3"><DiscreteObjectKeyFrame.Value><Visibility>Collapsed</Visibility></DiscreteObjectKeyFrame.Value></DiscreteObjectKeyFrame></ObjectAnimationUsingKeyFrames></Storyboard></BeginStoryboard></Trigger.ExitActions></Trigger></ControlTemplate.Triggers></ControlTemplate></Setter.Value></Setter>
</Style>

C#代码：

public class Switch :ToggleButton 
{static Switch(){DefaultStyleKeyProperty.OverrideMetadata(typeof(Switch), new FrameworkPropertyMetadata(typeof(Switch)));}
}

使用场景：

<UniformGrid Rows="1" HorizontalAlignment="Center"><c:Switch Height="60" IsChecked="False" Margin="0 0 20 0" /><c:Switch Height="60" IsChecked="True" Margin="0 0 20 0"/><c:Switch Height="60" IsChecked="False" Style="{StaticResource RotarySwitchStyle}" Margin="0 0 20 0"/><c:Switch Height="60" IsChecked="True" Style="{StaticResource RotarySwitchStyle}" Margin="0 0 20 0"/><c:Switch Height="60" IsChecked="False" Style="{StaticResource ButtonSwitchStyle}" Margin="0 0 20 0"/><c:Switch Height="60" IsChecked="True" Style="{StaticResource ButtonSwitchStyle}" Margin="0 0 20 0"/><ToggleButton Height="60" Style="{StaticResource Button2SwitchStyle}" Margin="0 0 20 0"/>
</UniformGrid>
