Radio Button

The radio button control presents a group of options from which only one may be selected at a time. A selected option is drawn as a filled circle, and an unselected option as an empty circle.

The content of the radio button control is presented as a label next to the circle.

It is possible for no options in a group to be selected, however as soon as one is selected, the radio button interaction cannot be stopped by the user.

Useful Properties

You will probably use these properties most often:

Property	Description
GroupName	Defines the name common to a group of options that will interact as radio buttons.
IsChecked	Whether a radio button option is selected (true) or unselected (false).
IsEnabled	Whether a radio button option is enabled. Disabled options are presented faded.

Example

This example shows two groups of radio buttons working independently:

<StackPanel Margin="20">
  <TextBlock Margin="0 10 0 5">First Group</TextBlock>
    <RadioButton GroupName="First Group"
              Content="First Option"/>
    <RadioButton GroupName="First Group"
              Content="Second Option"/>
    <RadioButton IsEnabled="False"
              GroupName="First Group"
              Content="Third Option"/>

  <TextBlock Margin="0 10 0 5">Second Group</TextBlock> 
    <RadioButton GroupName="Second Group"
              Content="Fourth Option"/>
    <RadioButton GroupName="Second Group"
              Content="Fifth Option"/>
</StackPanel>
