How do I make a CheckBox look like a RadioButton - wpf

Question

I wanna use a CheckBox but I want it to have the RadioButton chrome.
What's the easiest way to do this?

Answer 1

public partial class RadioCheckBox : CheckBox
{...}
RadioCheckBox.xaml:
<CheckBox
x:Class="WpfApplication1.RadioCheckBox"
...
xmlns:m="clr-namespace:WpfApplication1"
>
<CheckBox.Style>
<Style TargetType="{x:Type m:RadioCheckBox}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type m:RadioCheckBox}">
<Grid>
<RadioButton
IsChecked="{Binding RelativeSource={RelativeSource TemplatedParent},
Path=IsChecked, Mode=TwoWay}"
IsHitTestVisible="False" />
<CheckBox
IsChecked="{Binding RelativeSource={RelativeSource TemplatedParent},
Path=IsChecked, Mode=TwoWay}" Opacity="0"/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</CheckBox.Style>

Answer 2

This actually works just like I desired:
<Style TargetType="{x:Type CheckBox}" x:Key="CheckBox_RadioButtonStyle">
<Setter Property="Foreground"
Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
<Setter Property="Background" Value="#F4F4F4"/>
<Setter Property="BorderBrush" Value="#8E8F8F"/>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="FocusVisualStyle">
<Setter.Value>
<Style>
<Setter Property="Control.Template">
<Setter.Value>
<ControlTemplate>
<Rectangle Margin="1" SnapsToDevicePixels="True"
Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"
StrokeThickness="1" StrokeDashArray="1 2"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Setter.Value>
</Setter>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type CheckBox}">
<BulletDecorator Background="Transparent" SnapsToDevicePixels="true">
<BulletDecorator.Bullet>
<themes:BulletChrome BorderBrush="{TemplateBinding BorderBrush}"
Background="{TemplateBinding Background}"
IsChecked="{TemplateBinding IsChecked}"
RenderMouseOver="{TemplateBinding IsMouseOver}"
RenderPressed="{TemplateBinding IsPressed}" IsRound="True"/>
</BulletDecorator.Bullet>
<ContentPresenter
HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
Margin="{TemplateBinding Padding}" RecognizesAccessKey="True"
SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
</BulletDecorator>
<ControlTemplate.Triggers>
<Trigger Property="HasContent" Value="true">
<Setter Property="FocusVisualStyle"
Value="{StaticResource CheckRadioFocusVisual}"/>
<Setter Property="Padding" Value="4,0,0,0"/>
</Trigger>
<Trigger Property="IsEnabled" Value="false">
<Setter Property="Foreground"
Value="{DynamicResource {x:Static SystemColors.GrayTextBrushKey}}"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<!-------------------------------------->
<DataGridCheckBoxColumn x:Name="colSelected" Header="Selected"
ElementStyle="{StaticResource CheckBox_RadioButtonStyle}"/>

XAML:
<DataGrid x:Name="dg">
<DataGrid.GroupStyle>
<GroupStyle>
<GroupStyle.HeaderTemplate>
<DataTemplate>
<TextBlock Text="Test"/>
</DataTemplate>
</GroupStyle.HeaderTemplate>
</GroupStyle>
</DataGrid.GroupStyle>
<DataGrid.Resources>
<Style x:Key="myStyle" TargetType="CheckBox">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="CheckBox">
<RadioButton IsChecked="{Binding IsChecked, Mode=TwoWay, RelativeSource={RelativeSource AncestorType=CheckBox}}"
Content="{TemplateBinding Content}"
GroupName="{Binding MyProperty}"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</DataGrid.Resources>
<DataGrid.Columns>
<DataGridCheckBoxColumn ElementStyle="{StaticResource myStyle}"
EditingElementStyle="{StaticResource myStyle}"
IsReadOnly="False"
Binding="{Binding Flag, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
Header="1"/>
</DataGrid.Columns>
</DataGrid>
Code-Behind:
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
object[] items = new object[] {
new MyClass() { Flag = false, MyProperty = 1 },
new MyClass() { Flag = false, MyProperty = 1 },
new MyClass() { Flag = false, MyProperty = 1 },
new MyClass() { Flag = false, MyProperty = 1 },
new MyClass() { Flag = false, MyProperty = 1 },
new MyClass() { Flag = false, MyProperty = 2 },
new MyClass() { Flag = true, MyProperty = 2 },
new MyClass() { Flag = false, MyProperty = 2 },
};
ICollectionView cv = CollectionViewSource.GetDefaultView(items);
cv.GroupDescriptions.Add(new PropertyGroupDescription("MyProperty"));
this.dg.ItemsSource = cv;
}
public class MyClass : INotifyPropertyChanged
{
public int MyProperty { get; set; }
private bool flag;
public bool Flag
{
get { return this.flag; }
set
{
this.flag = value;
this.OnPropertyChanged("Flag");
}
}
#region INotifyPropertyChanged Members
public event PropertyChangedEventHandler PropertyChanged;
private void OnPropertyChanged(string propName)
{
if (this.PropertyChanged != null)
{
this.PropertyChanged(this, new PropertyChangedEventArgs(propName));
}
}
#endregion
}
}
