WPF 怎么把checkbox改成开关样式
先看一下效果吧：isChecked = false 的时候的效果

isChecked = true 的时候的效果

然后我们来实现一下这个效果吧
第一步：创建一个空的wpf项目；
第二步：在项目内里添加一个checkbox
<Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid>这个时候的checkbox的样子是如许的

第三步：在页面中右键checkbox，选择 编辑模板 ，再 编辑副本, 之后确定

vs就会给我们主动天生一个名为 ”CheckBoxStyle1” 的Checkbox的默认样式的代码,我们通过修改默认样式的代码，把普通的Checkbox酿成一个开关。
第四步：修改默认样式
<Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> 把之前的样式代码改成上面的代码，trigger部分，把报错的部分全部删除
这个时候，我们的开关样式就已经完成了
https://img2024.cnblogs.com/blog/2064545/202408/2064545-20240816164820136-952255523.png
我们现在必要添加一些trigger和动画来实现切换效果
第五步：添加动画和trigger
<Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid>上面这段代码就是表示不同状态下的不同动画效果，通过改变SwitchBoder的宽度和对齐方式，就可以实现了
然后我们再把这段动画效果运用到模板中,再添加3个trigger，就可以了
<Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>

</Grid> <Grid>

Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"

</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"

BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid> <Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
</Grid>到现在,样式和动画就已经完成了，我们再把代码全部剪切到App.xaml这个项目资源文件下面，再删掉style的命名,x:Key="CheckBoxStyle1"删掉，
如许子我们的项目内里的checkbox就都是开关的样式了，运行项目也不会报错啦,最后的代码如下
<Grid>
<CheckBox HorizontalAlignment="Center" IsChecked="True"
BorderBrush="Black" VerticalAlignment="Center"
Content="switch" Background="#FF00ADFF"/>
