RadioButton Styles and Templates

Silverlight

This topic describes the styles and templates for the RadioButton control. You can modify the default ControlTemplate to give the control a unique appearance. For more information, see Customizing the Appearance of an Existing Control by Using a ControlTemplate.

The RadioButton control does not have any named parts.

The following table lists the visual states for the RadioButton control.

VisualState Name

VisualStateGroup Name

Description

Normal

CommonStates

The default state.

MouseOver

CommonStates

The mouse pointer is positioned over the control.

Pressed

CommonStates

The control is pressed.

Disabled

CommonStates

The control is disabled.

Focused

FocusStates

The control has focus.

Unfocused

FocusStates

The control does not have focus.

Checked

CheckedStates

IsChecked is true.

Unchecked

CheckedStates

IsChecked is false.

Valid

ValidationStates

The control is valid.

InvalidFocused

ValidationStates

The control has focus but is not valid.

InvalidUnfocused

ValidationStates

The control is not valid and does not have focus.

The following shows the XML namespace mapping that you have to specify when you work with styles and templates.

<!-- XML Namespace mapping. -->
xmlns:vsm="clr-namespace:System.Windows;assembly=System.Windows"
NoteNote:

The default templates still specify the vsm: XML namespace mapping for the VisualStateManager element for legacy reasons. You can however, use the VisualStateManager element without specifying the vsm: mapping.

The following XAML shows the default style and template for the RadioButton control.

The default ControlTemplate for RadioButton references the ControlTemplate for ValidationTooltip. The following XAML shows the ControlTemplate for ValidationTooltip that you must specify when you work with the RadioButton control template:


<ControlTemplate x:Key="ValidationToolTipTemplate">
      <Grid x:Name="Root" Margin="5,0" RenderTransformOrigin="0,0" Opacity="0">
          <Grid.RenderTransform>
              <TranslateTransform x:Name="xform" X="-25"/>
          </Grid.RenderTransform>
          <vsm:VisualStateManager.VisualStateGroups>
              <vsm:VisualStateGroup Name="OpenStates">
                  <vsm:VisualStateGroup.Transitions>
