wpf 可以取消的单选checkbox

利用radioButton的groupName分组互斥。。再解决radiobutton的取消选择的问题。给radiobutton加了一个像checkbox的样式

2个方式：

效果图

第一种usecontrol：

xaml：

View Code

<RadioButton x:Class="GEMS.Windows.Controls.UserControls.SingleCheckBox"xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" mc:Ignorable="d" Click="RadioButton_Click_1" Unchecked="RadioButton_Unchecked_1" Style="{DynamicResource SingleCheckBox}"><RadioButton.Resources><Style x:Key="RadioButtonFocusVisual"><Setter Property="Control.Template"><Setter.Value><ControlTemplate><Border><Rectangle Margin="15,0,0,0"StrokeThickness="1"Stroke="#60000000"StrokeDashArray="1 2"/></Border></ControlTemplate></Setter.Value></Setter></Style><SolidColorBrush x:Key="DisabledForegroundBrush" Color="#888" /><SolidColorBrush x:Key="DisabledBorderBrush" Color="#AAA" /><SolidColorBrush x:Key="DisabledBackgroundBrush" Color="#EEE" /><SolidColorBrush x:Key="Normalborderbrush" Color="#5d7fad" /><Style x:Key="SingleCheckBox"  TargetType="{x:Type RadioButton}"><Setter Property="GroupName" Value="Single"/><Setter Property="SnapsToDevicePixels" Value="true"/><Setter Property="OverridesDefaultStyle" Value="true"/><Setter Property="Foreground" Value="#071f3b"/><Setter Property="FontFamily" Value="Arial"></Setter><Setter Property="FontSize" Value="14"></Setter><Setter Property="FocusVisualStyle"    Value="{StaticResource RadioButtonFocusVisual}"/><Setter Property="Template"><Setter.Value><ControlTemplate TargetType="{x:Type RadioButton}"><BulletDecorator Background="Transparent"><BulletDecorator.Bullet><Border x:Name="Border"  Width="20" Height="20" CornerRadius="4" Background="#ffffff" BorderThickness="1" BorderBrush="{StaticResource Normalborderbrush}"><Path Width="14" Height="11" Margin="5,2,0,0" x:Name="CheckMark" SnapsToDevicePixels="False" Stroke="#173e78" StrokeThickness="2" Data="M 0 5 L 3 10 10 0" /><!--<Path Width="14" Height="11" Margin="5,2,0,0" x:Name="CheckMark" SnapsToDevicePixels="False" Stroke="{StaticResource Glyphbrush}" StrokeThickness="2" Data="M 0 0 L 7 7 M 0 7 L 7 0" /> cross--></Border></BulletDecorator.Bullet><ContentPresenter Margin="4,0,0,0"VerticalAlignment="Center"HorizontalAlignment="Left"RecognizesAccessKey="True"/></BulletDecorator><ControlTemplate.Triggers><Trigger Property="IsChecked" Value="false"><Setter TargetName="CheckMark" Property="Visibility" Value="Collapsed"/></Trigger><Trigger Property="IsChecked" Value="{x:Null}"><Setter TargetName="CheckMark" Property="Data" Value="M 0 7 L 7 0" /></Trigger><Trigger Property="IsMouseOver" Value="true"><Setter TargetName="Border" Property="Background" Value="#ffffff" /></Trigger><Trigger Property="IsPressed" Value="true"><Setter TargetName="Border" Property="Background" Value="#ffffff" /></Trigger><Trigger Property="IsEnabled" Value="false"><Setter TargetName="Border" Property="Background" Value="{StaticResource DisabledBackgroundBrush}" /><Setter TargetName="Border" Property="BorderBrush" Value="{StaticResource DisabledBorderBrush}" /><Setter Property="Foreground" Value="{StaticResource DisabledForegroundBrush}"/></Trigger></ControlTemplate.Triggers></ControlTemplate></Setter.Value></Setter></Style></RadioButton.Resources>
</RadioButton>

xaml的后台cs

View Code

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;namespace GEMS.Windows.Controls.UserControls
{/// <summary>/// Interaction logic for SingleCheckBox.xaml/// </summary>public partial class SingleCheckBox : RadioButton{private bool hasCheck;/// <summary>/// /// </summary>public bool HasCheck{get { return hasCheck; }set { hasCheck = value; }}public SingleCheckBox(){InitializeComponent();}private void RadioButton_Click_1(object sender, RoutedEventArgs e){if (this.HasCheck == false){this.HasCheck = true;this.IsChecked = true;}else{this.HasCheck = false;this.IsChecked = false;}}private void RadioButton_Unchecked_1(object sender, RoutedEventArgs e){this.HasCheck = false;}}
}

第2种customercontrol

注意的是在generic里面需要去引用singleCheckBox.xaml

View Code

<ResourceDictionaryxmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"><ResourceDictionary.MergedDictionaries><ResourceDictionary Source="/GEMS.Windows.Controls.CustomControls;component/Themes/CustomRichTextBox.xaml"/><ResourceDictionary Source="/GEMS.Windows.Controls.CustomControls;component/Themes/ColorPicker.xaml"/><ResourceDictionary Source="/GEMS.Windows.Controls.CustomControls;component/Themes/MultipleDropDownBox.xaml"/><ResourceDictionary Source="/GEMS.Windows.Controls.CustomControls;component/Themes/SingleCheckBox.xaml"/></ResourceDictionary.MergedDictionaries>
</ResourceDictionary>

在singleCheckBox.xaml中定义样式

View Code

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:local="clr-namespace:GEMS.Windows.Controls.CustomControls"><Style x:Key="RadioButtonFocusVisual"><Setter Property="Control.Template"><Setter.Value><ControlTemplate><Border><Rectangle Margin="15,0,0,0"StrokeThickness="1"Stroke="#60000000"StrokeDashArray="1 2"/></Border></ControlTemplate></Setter.Value></Setter></Style><SolidColorBrush x:Key="DisabledForegroundBrush" Color="#888" /><SolidColorBrush x:Key="DisabledBorderBrush" Color="#AAA" /><SolidColorBrush x:Key="DisabledBackgroundBrush" Color="#EEE" /><SolidColorBrush x:Key="Normalborderbrush" Color="#5d7fad" /><Style  TargetType="{x:Type local:SingleCheckBox}"><Setter Property="GroupName" Value="Single"/><Setter Property="SnapsToDevicePixels" Value="true"/><Setter Property="Foreground" Value="#071f3b"/><Setter Property="FontFamily" Value="Arial"></Setter><Setter Property="FontSize" Value="14"></Setter><Setter Property="Background" Value="Red"/><Setter Property="Template"><Setter.Value><ControlTemplate TargetType="{x:Type local:SingleCheckBox}"><BulletDecorator Background="Transparent"><BulletDecorator.Bullet><Border x:Name="Border"  Width="20" Height="20" CornerRadius="4" Background="#ffffff" BorderThickness="1" BorderBrush="Black"><Path Width="14" Height="11" Margin="5,2,0,0" x:Name="CheckMark" SnapsToDevicePixels="False" Stroke="#173e78" StrokeThickness="2" Data="M 0 5 L 3 10 10 0" /></Border></BulletDecorator.Bullet><ContentPresenter Margin="4,0,0,0"VerticalAlignment="Center"HorizontalAlignment="Left"RecognizesAccessKey="True"/></BulletDecorator><ControlTemplate.Triggers><Trigger Property="IsChecked" Value="false"><Setter TargetName="CheckMark" Property="Visibility" Value="Collapsed"/></Trigger><Trigger Property="IsChecked" Value="{x:Null}"><Setter TargetName="CheckMark" Property="Data" Value="M 0 7 L 7 0" /></Trigger><Trigger Property="IsMouseOver" Value="true"><Setter TargetName="Border" Property="Background" Value="#ffffff" /></Trigger><Trigger Property="IsPressed" Value="true"><Setter TargetName="Border" Property="Background" Value="#ffffff" /></Trigger><Trigger Property="IsEnabled" Value="false"><Setter TargetName="Border" Property="Background" Value="{StaticResource DisabledBackgroundBrush}" /><Setter TargetName="Border" Property="BorderBrush" Value="{StaticResource DisabledBorderBrush}" /><Setter Property="Foreground" Value="{StaticResource DisabledForegroundBrush}"/></Trigger></ControlTemplate.Triggers></ControlTemplate></Setter.Value></Setter></Style>
</ResourceDictionary>

在singleCheckBox.cs中
注意为了通知wpf正在提供一个信阳市，需要在自定义控件类的静态构造中调用overrideMetadata（）。。我们使用DefaultStyleKeyProperty来调用这个方式

static SingleCheckBox()

{

DefaultStyleKeyProperty.OverrideMetadata(

typeof(SingleCheckBox), newFrameworkPropertyMetadata(typeof(SingleCheckBox

)));

}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;namespace GEMS.Windows.Controls.CustomControls
{public  class SingleCheckBox:RadioButton{private bool hasCheck;/// <summary>/// /// </summary>public bool HasCheck{get { return hasCheck; }set { hasCheck = value; }}public SingleCheckBox(){this.Unchecked += SingleCheckBox_Unchecked;this.Click += SingleCheckBox_Click;}void SingleCheckBox_Unchecked(object sender, System.Windows.RoutedEventArgs e){this.HasCheck = false;}static SingleCheckBox(){DefaultStyleKeyProperty.OverrideMetadata(typeof(SingleCheckBox), new FrameworkPropertyMetadata(typeof(SingleCheckBox)));//
      }void SingleCheckBox_Click(object sender, System.Windows.RoutedEventArgs e){if (this.HasCheck == false){this.HasCheck = true;this.IsChecked = true;}else{this.HasCheck = false;this.IsChecked = false;}}}
}
