  NameDescription
Public fieldStatic memberSupported by Silverlight for Windows PhoneGroupNamePropertyIdentifies the GroupName dependency property.
Top

The RadioButton is a control that is usually used as an item in a group of RadioButton controls.

The following illustration shows two RadioButton controls.

RadioButton Controls

RadioButton controls.

You can create a single RadioButton. You group RadioButton controls by putting them inside a parent or by setting the GroupName property on each RadioButton. RadioButton and CheckBox controls have a similar function: they offer choices a user can select or clear. When RadioButton elements are grouped, the buttons are mutually exclusive. A user can select only one item at a time in a RadioButton group.

A RadioButton has two states: selected (checked) or cleared (unchecked). Whether a RadioButton is selected is determined by the state of its IsChecked property. When a RadioButton is selected, the IsChecked property is true. When a RadioButton is cleared, the IsChecked property is false. A RadioButton can be cleared by clicking another RadioButton in the group, but it cannot be cleared by clicking it again. However, a RadioButton can be cleared programmatically by setting its IsChecked property to false.

RadioButton is a ContentControl. Its content property is Content. For more information, see Control Content Models.

Customizing the RadioButton Control

To apply the same property settings to multiple RadioButton controls, use the Style property. To change the visual structure and visual behavior of a RadioButton, copy and modify its default style and template. For more information, see Control Customization.

Dependency properties for this control might be set by the default style of the control. If a dependency property for a RadioButton is set by its default style, the property might change from its default value when the RadioButton appears in the application. For more information, see Dependency Property Value Precedence. You can get the default style and template for RadioButton from RadioButton Styles and Templates.

NoteNote:

Setting a visual property will only have an effect if that property is both present in RadioButton control's default template and is set by using a TemplateBinding. You can find a list of visual properties in the "Changing the Visual Structure of a Control" section of Customizing the Appearance of an Existing Control by Using a ControlTemplate.

The following example shows two panels that contain three radio buttons each. One radio button from each panel are grouped together. The remaining two radio buttons on each panel are not grouped explicitly, which means they are grouped together since they share the same parent control. When you run this sample and select a radio button, a TextBlock displays the name of the group, or "grouped to panel" for a radio button without an explicit group name, and the name of the radio button.

Run this sample


private void HandleCheck(object sender, RoutedEventArgs e)
{
    RadioButton rb = sender as RadioButton;
    choiceTextBlock.Text = "You chose: " + rb.GroupName + ": " + rb.Name;
}



        <TextBlock Text="First Group:"  Margin="5" />
        <RadioButton x:Name="TopButton" Margin="5" Checked="HandleCheck"
		     GroupName="First Group" Content="First Choice" />
        <RadioButton x:Name="MiddleButton" Margin="5" Checked="HandleCheck"
		     GroupName="First Group" Content="Second Choice" />
        <TextBlock Text="Ungrouped:" Margin="5" />
        <RadioButton x:Name="LowerButton" Margin="5" Checked="HandleCheck"
		    Content="Third Choice" />
        <TextBlock x:Name="choiceTextBlock" Margin="5" />
