一.前言

  申明:WPF自定义控件与样式是一个系列文章,前后是有些关联的,但大多是按照由简到繁的顺序逐步发布的等

本文主要内容:

  • CheckBox复选框的自定义样式,有两种不同的风格实现;
  • RadioButton单选框自定义样式,有两种不同的风格实现;

二. CheckBox自定义样式

2.1 CheckBox基本样式

标准CheckBox样式代码如下,实现了三态的显示,其中不同状态的图标用了字体图标(关于字体图标,可以参考本文末尾附录链接)

<Style x:Key="DefaultCheckBox" TargetType="{x:Type CheckBox}">
<Setter Property="Background" Value="Transparent"></Setter>
<Setter Property="Foreground" Value="{StaticResource TextForeground}"></Setter>
<Setter Property="Padding" Value="0"></Setter>
<Setter Property="local:ControlAttachProperty.FIconMargin" Value="1, 1, 3, 1"></Setter>
<Setter Property="local:ControlAttachProperty.FIconSize" Value="22"></Setter>
<Setter Property="FontSize" Value="{StaticResource FontSize}"></Setter>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type CheckBox}">
<Grid x:Name="grid" Margin="{TemplateBinding Padding}" VerticalAlignment="Center">
<StackPanel Orientation="Horizontal" VerticalAlignment="Center">
<TextBlock x:Name="icon" Style="{StaticResource FIcon}" Text=""
FontSize="{TemplateBinding local:ControlAttachProperty.FIconSize}"
Margin="{TemplateBinding local:ControlAttachProperty.FIconMargin}"
Foreground="{TemplateBinding Foreground}"/>
<ContentPresenter VerticalAlignment="Center"/>
</StackPanel>
</Grid>
<!--触发器:设置选中状态符号-->
<ControlTemplate.Triggers>
<Trigger Property="IsChecked" Value="true">
<Setter Property="Text" Value="" TargetName="icon" ></Setter>
<Setter Property="Foreground" Value="{StaticResource CheckedForeground}"></Setter>
</Trigger>
<Trigger Property="IsChecked" Value="{x:Null}">
<Setter Property="Text" Value="" TargetName="icon" ></Setter>
</Trigger>
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="Foreground" Value="{StaticResource MouseOverForeground}"></Setter>
</Trigger>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Opacity" Value="{StaticResource DisableOpacity}" TargetName="grid" ></Setter>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

使用示例及效果:

 <CheckBox Margin="3">男</CheckBox>
<CheckBox Margin="3">女</CheckBox>
<CheckBox Margin="3" IsChecked="{x:Null}">其他</CheckBox>
<CheckBox Margin="3" IsChecked="{x:Null}">女</CheckBox>
<CheckBox Margin="3" IsEnabled="False">我被禁用了</CheckBox>
<CheckBox Margin="3" IsEnabled="False" IsChecked="{x:Null}">我被禁用了</CheckBox>
<CheckBox Margin="3" IsEnabled="False" IsChecked="True">我被禁用了</CheckBox>

2.2 CheckBox另一种样式

在移动端比较常见的一种复选效果,先看看效果

这个代码是很久以前写的,用的控件的形式实现的,可以纯样式实现,更简洁,懒得改了。C#代码:

/// <summary>
/// BulletCheckBox.xaml 的交互逻辑
/// </summary>
public class BulletCheckBox : CheckBox
{
public static readonly DependencyProperty TextProperty = DependencyProperty.Register(
"Text", typeof(string), typeof(BulletCheckBox), new PropertyMetadata("Off"));
/// <summary>
/// 默认文本(未选中)
/// </summary>
public string Text
{
get { return (string)GetValue(TextProperty); }
set { SetValue(TextProperty, value); }
} public static readonly DependencyProperty CheckedTextProperty = DependencyProperty.Register(
"CheckedText", typeof(string), typeof(BulletCheckBox), new PropertyMetadata("On"));
/// <summary>
/// 选中状态文本
/// </summary>
public string CheckedText
{
get { return (string)GetValue(CheckedTextProperty); }
set { SetValue(CheckedTextProperty, value); }
} public static readonly DependencyProperty CheckedForegroundProperty =
DependencyProperty.Register("CheckedForeground", typeof(Brush), typeof(BulletCheckBox), new PropertyMetadata(Brushes.WhiteSmoke));
/// <summary>
/// 选中状态前景样式
/// </summary>
public Brush CheckedForeground
{
get { return (Brush)GetValue(CheckedForegroundProperty); }
set { SetValue(CheckedForegroundProperty, value); }
} public static readonly DependencyProperty CheckedBackgroundProperty =
DependencyProperty.Register("CheckedBackground", typeof(Brush), typeof(BulletCheckBox), new PropertyMetadata(Brushes.LimeGreen));
/// <summary>
/// 选中状态背景色
/// </summary>
public Brush CheckedBackground
{
get { return (Brush)GetValue(CheckedBackgroundProperty); }
set { SetValue(CheckedBackgroundProperty, value); }
} static BulletCheckBox()
{
DefaultStyleKeyProperty.OverrideMetadata(typeof(BulletCheckBox), new FrameworkPropertyMetadata(typeof(BulletCheckBox)));
}
}

样式代码,状态变换用了点小动画,为了支持缩放,用了一个Viewbox来包装内容:

<Style TargetType="{x:Type local:BulletCheckBox}">
<Setter Property="Background" Value="#FF4A9E4A"></Setter>
<Setter Property="Foreground" Value="#DDE8E1"></Setter>
<Setter Property="CheckedForeground" Value="White"></Setter>
<Setter Property="CheckedBackground" Value="#FF0CC50C"></Setter>
<Setter Property="FontSize" Value="13"></Setter>
<Setter Property="Cursor" Value="Hand"></Setter>
<Setter Property="Width" Value="75"></Setter>
<Setter Property="Height" Value="28"></Setter>
<Setter Property="Margin" Value="1"></Setter>
<Setter Property="Template">
<Setter.Value>
<!--控件模板-->
<ControlTemplate TargetType="{x:Type local:BulletCheckBox}">
<Viewbox Stretch="Uniform" VerticalAlignment="Center" HorizontalAlignment="Center">
<Border x:Name="border" Width="75" Height="28" Background="{TemplateBinding Background}" SnapsToDevicePixels="True"
Margin="{TemplateBinding Margin}" CornerRadius="14">
<StackPanel Orientation="Horizontal">
<!--状态球-->
<Border x:Name="state" Width="24" Height="24" Margin="3,2,1,2" CornerRadius="12" SnapsToDevicePixels="True"
Background="{TemplateBinding Foreground}">
<Border.RenderTransform>
<TranslateTransform x:Name="transState" X="0"></TranslateTransform>
</Border.RenderTransform>
</Border>
<!--文本框-->
<TextBlock Width="40" Foreground="{TemplateBinding Foreground}" x:Name="txt" Text="{TemplateBinding Text}" VerticalAlignment="Center" TextAlignment="Center">
<TextBlock.RenderTransform>
<TranslateTransform x:Name="transTxt" X="0"></TranslateTransform>
</TextBlock.RenderTransform>
</TextBlock>
</StackPanel>
</Border>
</Viewbox> <!--触发器:设置选中状态符号-->
<ControlTemplate.Triggers>
<Trigger Property="IsChecked" Value="True">
<Setter Property="Text" Value="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, Path=CheckedText}" TargetName="txt"/>
<Setter Property="Background" Value="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, Path=CheckedForeground}" TargetName="state"/>
<Setter Property="Foreground" Value="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, Path=CheckedForeground}" TargetName="txt"/>
<Setter Property="Background" Value="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, Path=CheckedBackground}" TargetName="border"/>
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetName="transState" Storyboard.TargetProperty="X" To="45" Duration="0:0:0.2" />
<DoubleAnimation Storyboard.TargetName="transTxt" Storyboard.TargetProperty="X" To="-24" Duration="0:0:0.2" />
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
<Trigger.ExitActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetName="transState" Storyboard.TargetProperty="X" To="0" Duration="0:0:0.2" />
<DoubleAnimation Storyboard.TargetName="transTxt" Storyboard.TargetProperty="X" To="0" Duration="0:0:0.2" />
</Storyboard>
</BeginStoryboard>
</Trigger.ExitActions>
</Trigger> <Trigger Property="IsEnabled" Value="false">
<Setter Property="Opacity" Value="{StaticResource DisableOpacity}" TargetName="border"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

使用示例:

   <kc:BulletCheckBox />
<kc:BulletCheckBox Text="不开窍" CheckedText="开启" IsChecked="True" />
<kc:BulletCheckBox Text="不开窍" CheckedText="开启" IsChecked="True" Height="24" Width="60" />

三.RadioButton自定义样式

3.1 RadioButon基本样式

标准单选控件的样式很简单,用不同图标标识不同状态,然后触发器控制不同状态的显示效果。

<!--默认样式-->
<Style x:Key="DefaultRadioButton" TargetType="{x:Type RadioButton}">
<Setter Property="Background" Value="Transparent"></Setter>
<Setter Property="Foreground" Value="{StaticResource TextForeground}"></Setter>
<Setter Property="Padding" Value="0"></Setter>
<Setter Property="local:ControlAttachProperty.FIconMargin" Value="1, 1, 3, 1"></Setter>
<Setter Property="local:ControlAttachProperty.FIconSize" Value="25"></Setter>
<Setter Property="FontSize" Value="{StaticResource FontSize}"></Setter>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type RadioButton}">
<Grid x:Name="grid" Margin="{TemplateBinding Padding}" VerticalAlignment="Center">
<StackPanel Orientation="Horizontal" VerticalAlignment="Center">
<TextBlock x:Name="icon" Text="" Style="{StaticResource FIcon}" SnapsToDevicePixels="True"
FontSize="{TemplateBinding local:ControlAttachProperty.FIconSize}"
Margin="{TemplateBinding local:ControlAttachProperty.FIconMargin}"
Foreground="{TemplateBinding Foreground}"/>
<ContentPresenter VerticalAlignment="Center"/>
</StackPanel>
</Grid>
<!--触发器:设置选中状态符号-->
<ControlTemplate.Triggers>
<Trigger Property="IsChecked" Value="true">
<Setter Property="Text" Value="" TargetName="icon" ></Setter>
<Setter Property="Foreground" Value="{StaticResource CheckedForeground}"></Setter>
</Trigger>
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="Foreground" Value="{StaticResource MouseOverForeground}"></Setter>
</Trigger>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Opacity" Value="{StaticResource DisableOpacity}" TargetName="grid" ></Setter>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

使用示例:

 <RadioButton Margin="3" core:ControlAttachProperty.FIconSize="18">男</RadioButton>
<RadioButton Margin="3" core:ControlAttachProperty.FIconSize="20">女</RadioButton>
<RadioButton Margin="3" IsChecked="{x:Null}" core:ControlAttachProperty.FIconSize="22">其他</RadioButton>
<RadioButton Margin="3" IsChecked="{x:Null}" core:ControlAttachProperty.FIconSize="24">女</RadioButton>
<RadioButton Margin="3" IsChecked="{x:Null}" core:ControlAttachProperty.FIconSize="26">女</RadioButton>
<RadioButton Margin="3" IsEnabled="False">我被禁用了</RadioButton>
<RadioButton Margin="3" IsEnabled="False" IsChecked="{x:Null}">我被禁用了</RadioButton>

效果图:

3.2 RadioButton淘宝、京东物品尺码单项样式

先看看效果:

样式定义也很简单,右下角那个小勾勾用的是一个字体图标,可以根据需要调整大小。

<Style x:Key="BoxRadioButton" TargetType="{x:Type RadioButton}">
<Setter Property="Background" Value="Transparent"></Setter>
<Setter Property="Foreground" Value="{StaticResource TextForeground}"></Setter>
<Setter Property="Padding" Value="3 2 3 2"></Setter>
<Setter Property="FontSize" Value="{StaticResource FontSize}"></Setter>
<Setter Property="BorderThickness" Value="2"></Setter>
<Setter Property="Height" Value="auto"></Setter>
<Setter Property="SnapsToDevicePixels" Value="true"></Setter>
<Setter Property="BorderBrush" Value="{StaticResource ControlBorderBrush}" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type RadioButton}">
<Grid x:Name="grid" VerticalAlignment="Center">
<Border BorderThickness="{TemplateBinding BorderThickness}" BorderBrush="{TemplateBinding BorderBrush}" Height="{TemplateBinding Height}" HorizontalAlignment="Center"
Background="{TemplateBinding Background}" Width="{TemplateBinding Width}">
<ContentPresenter VerticalAlignment="Center" HorizontalAlignment="Center" Margin="{TemplateBinding Padding}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
</Border>
<!--选中的状态标识-->
<TextBlock Text="" x:Name="checkState" Style="{StaticResource FIcon}" VerticalAlignment="Bottom" Visibility="Collapsed"
FontSize="14" Margin="1" HorizontalAlignment="Right" Foreground="{StaticResource CheckedForeground}"/>
</Grid>
<!--触发器:设置选中状态符号-->
<ControlTemplate.Triggers>
<Trigger Property="IsChecked" Value="true">
<Setter Property="Visibility" Value="Visible" TargetName="checkState" ></Setter>
<Setter Property="BorderBrush" Value="{StaticResource CheckedForeground}"></Setter>
</Trigger>
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="BorderBrush" Value="{StaticResource MouseOverForeground}"></Setter>
</Trigger>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Opacity" Value="{StaticResource DisableOpacity}" TargetName="grid" ></Setter>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

示例代码:

<RadioButton Style="{StaticResource BoxRadioButton}" Margin="1">近3天</RadioButton>
<RadioButton Style="{StaticResource BoxRadioButton}" Margin="1">近7天</RadioButton>
<RadioButton Style="{StaticResource BoxRadioButton}" Margin="1">本月</RadioButton>
<RadioButton Style="{StaticResource BoxRadioButton}" Margin="1">自定义</RadioButton>
<RadioButton Style="{StaticResource BoxRadioButton}" Margin="1">2012.05.12-2015.12.14</RadioButton>

补充说明,上面样式中有用到附加属性,如

ControlAttachProperty.FIconMargin" Value="1, 1, 3, 1":复选框或单选框字体图标的边距

ControlAttachProperty.FIconSize" Value="25":复选框或单选框字体图标的大小

关于附加属性可以参考上一篇(本文末尾链接),C#定义代码:

#region FIconProperty 字体图标
/// <summary>
/// 字体图标
/// </summary>
public static readonly DependencyProperty FIconProperty = DependencyProperty.RegisterAttached(
"FIcon", typeof(string), typeof(ControlAttachProperty), new FrameworkPropertyMetadata("")); public static string GetFIcon(DependencyObject d)
{
return (string)d.GetValue(FIconProperty);
} public static void SetFIcon(DependencyObject obj, string value)
{
obj.SetValue(FIconProperty, value);
}
#endregion #region FIconSizeProperty 字体图标大小
/// <summary>
/// 字体图标
/// </summary>
public static readonly DependencyProperty FIconSizeProperty = DependencyProperty.RegisterAttached(
"FIconSize", typeof(double), typeof(ControlAttachProperty), new FrameworkPropertyMetadata(12D)); public static double GetFIconSize(DependencyObject d)
{
return (double)d.GetValue(FIconSizeProperty);
} public static void SetFIconSize(DependencyObject obj, double value)
{
obj.SetValue(FIconSizeProperty, value);
}
#endregion #region FIconMarginProperty 字体图标边距
/// <summary>
/// 字体图标
/// </summary>
public static readonly DependencyProperty FIconMarginProperty = DependencyProperty.RegisterAttached(
"FIconMargin", typeof(Thickness), typeof(ControlAttachProperty), new FrameworkPropertyMetadata(null)); public static Thickness GetFIconMargin(DependencyObject d)
{
return (Thickness)d.GetValue(FIconMarginProperty);
} public static void SetFIconMargin(DependencyObject obj, Thickness value)
{
obj.SetValue(FIconMarginProperty, value);
}
#endregion
