詳解WPF如何把checkbox改成開(kāi)關(guān)樣式

這篇文章主要為大家詳細(xì)介紹了WPF如何把checkbox改成開(kāi)關(guān)樣式,文中的示例代碼講解詳細(xì),具有一定的借鑒價(jià)值,有需要的小伙伴可以參考一下
先看一下效果吧：
isChecked = false 的時(shí)候的效果
isChecked = true 的時(shí)候的效果
然后我們來(lái)實(shí)現(xiàn)一下這個(gè)效果吧
第一步：創(chuàng)建一個(gè)空的wpf項(xiàng)目；
第二步：在項(xiàng)目里面添加一個(gè)checkbox
<Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid>這個(gè)時(shí)候的checkbox的樣子是這樣的
第三步：在頁(yè)面中右鍵checkbox，選擇 編輯模板 ，再 編輯副本, 之后確定
vs就會(huì)給我們自動(dòng)生成一個(gè)名為 ”CheckBoxStyle1” 的Checkbox的默認(rèn)樣式的代碼,我們通過(guò)修改默認(rèn)樣式的代碼，把普通的Checkbox變成一個(gè)開(kāi)關(guān)。
第四步：修改默認(rèn)樣式
<Grid x:Name="templateRoot" Background="Transparent" SnapsToDevicePixels="True">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Border x:Name="PART_Border" BorderBrush="{TemplateBinding BorderBrush}" Background="{TemplateBinding Background}"
BorderThickness="1" Height="14" Width="25" CornerRadius="5">
<Border x:Name="SwitchBorder" BorderThickness="1" BorderBrush="Gray" Background="White" Width="10"
Margin="1" CornerRadius="5" HorizontalAlignment="Right"/>
</Border>
<ContentPresenter x:Name="contentPresenter" Grid.Column="1" Focusable="False" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
</Grid>把之前的樣式代碼改成上面的代碼，trigger部分，把報(bào)錯(cuò)的部分全部刪除
這個(gè)時(shí)候，我們的開(kāi)關(guān)樣式就已經(jīng)完成了
我們現(xiàn)在需要添加一些trigger和動(dòng)畫(huà)來(lái)實(shí)現(xiàn)切換效果
第五步：添加動(dòng)畫(huà)和trigger
<Storyboard x:Key="SwitchChecked">
<DoubleAnimationUsingKeyFrames Storyboard.TargetName="SwitchBorder" Storyboard.TargetProperty="(FrameworkElement.Width)">
<EasingDoubleKeyFrame KeyTime="00:00:00" Value="10"/>
<EasingDoubleKeyFrame KeyTime="00:00:00.2500000" Value="20"/>
<EasingDoubleKeyFrame KeyTime="00:00:00.5000000" Value="10"/>
</DoubleAnimationUsingKeyFrames>
<ObjectAnimationUsingKeyFrames Storyboard.TargetName="SwitchBorder" Storyboard.TargetProperty="(FrameworkElement.HorizontalAlignment)">
<DiscreteObjectKeyFrame KeyTime="00:00:00" Value="{x:Static HorizontalAlignment.Left}"/>
<DiscreteObjectKeyFrame KeyTime="00:00:00.2500000" Value="{x:Static HorizontalAlignment.Right}"/>
<DiscreteObjectKeyFrame KeyTime="00:00:00.5000000" Value="{x:Static HorizontalAlignment.Right}"/>
</ObjectAnimationUsingKeyFrames>
</Storyboard>
<Storyboard x:Key="SwitchUnchecked">
<DoubleAnimationUsingKeyFrames Storyboard.TargetName="SwitchBorder" Storyboard.TargetProperty="(FrameworkElement.Width)">
<EasingDoubleKeyFrame KeyTime="00:00:00" Value="10"/>
<EasingDoubleKeyFrame KeyTime="00:00:00.2500000" Value="20"/>
<EasingDoubleKeyFrame KeyTime="00:00:00.5000000" Value="10"/>
</DoubleAnimationUsingKeyFrames>
<ObjectAnimationUsingKeyFrames Storyboard.TargetName="SwitchBorder" Storyboard.TargetProperty="(FrameworkElement.HorizontalAlignment)">
<DiscreteObjectKeyFrame KeyTime="00:00:00" Value="{x:Static HorizontalAlignment.Right}"/>
<DiscreteObjectKeyFrame KeyTime="00:00:00.2500000" Value="{x:Static HorizontalAlignment.Left}"/>
<DiscreteObjectKeyFrame KeyTime="00:00:00.5000000" Value="{x:Static HorizontalAlignment.Left}"/>
</ObjectAnimationUsingKeyFrames>
</Storyboard>上面這段代碼就是表示不同狀態(tài)下的不同動(dòng)畫(huà)效果，通過(guò)改變SwitchBoder的寬度和對(duì)齊方式，就可以實(shí)現(xiàn)了
然后我們?cè)侔堰@段動(dòng)畫(huà)效果運(yùn)用到模板中,再添加3個(gè)trigger，就可以了
<ControlTemplate.Triggers>
<Trigger Property="HasContent" Value="true">
<Setter Property="FocusVisualStyle" Value="{StaticResource OptionMarkFocusVisual}"/>
<Setter Property="Padding" Value="4,-1,0,0"/>
</Trigger>
<EventTrigger RoutedEvent="{x:Static CheckBox.CheckedEvent}">
<BeginStoryboard Storyboard="{StaticResource SwitchChecked}"/>
</EventTrigger>
<EventTrigger RoutedEvent="{x:Static CheckBox.UncheckedEvent}">
<BeginStoryboard Storyboard="{StaticResource SwitchUnchecked}"/>
</EventTrigger>
<Trigger Property="IsEnabled" Value="false">
<Setter Property="Background" TargetName="PART_Border" Value="{StaticResource OptionMark.Disabled.Background}"/>
<Setter Property="BorderBrush" TargetName="PART_Border" Value="{StaticResource OptionMark.Disabled.Border}"/>
</Trigger>
<Trigger Property="IsChecked" Value="False">
<Setter Property="Background" Value="White" TargetName="PART_Border"/>
<Setter Property="HorizontalAlignment" Value="Left" TargetName="SwitchBorder"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="BorderBrush" TargetName="PART_Border" Value="{StaticResource OptionMark.MouseOver.Border}"/>
</Trigger>
</ControlTemplate.Triggers>到現(xiàn)在,樣式和動(dòng)畫(huà)就已經(jīng)完成了，我們?cè)侔汛a全部剪切到App.xaml這個(gè)項(xiàng)目資源文件下面，再刪掉style的命名,x:Key="CheckBoxStyle1"刪掉，
這樣子我們的項(xiàng)目里面的checkbox就都是開(kāi)關(guān)的樣式了，運(yùn)行項(xiàng)目也不會(huì)報(bào)錯(cuò)啦,最后的代碼如下
<Application.Resources>
<Storyboard x:Key="SwitchChecked">
<DoubleAnimationUsingKeyFrames Storyboard.TargetName="SwitchBorder" Storyboard.TargetProperty="(FrameworkElement.Width)">
<EasingDoubleKeyFrame KeyTime="00:00:00" Value="10"/>

<EasingDoubleKeyFrame KeyTime="00:00:00.5000000" Value="10"/>
</DoubleAnimationUsingKeyFrames>
