Radio Button groups

• There is no Tab Group box in the toolbox
• Solution: use GroupName in the .xaml file
• eg.

            <RadioButton Content="Male" Height="72" HorizontalAlignment="Left" Margin="293,102,0,0" Name="maleRadioButton" VerticalAlignment="Top" Checked="maleRadioButton_Checked"

                         GroupName="MyRadioBtnGroup"/>

            <RadioButton Content="Female" Height="72" HorizontalAlignment="Left" Margin="292,177,0,0" Name="femaleRadioButton" VerticalAlignment="Top" Checked="femaleRadioButton_Checked" 

                         GroupName="MyRadioBtnGroup"/>

The traditional way of dealing with multiple radio buttons, with "one checked" behaviour, is to put the Radio Buttons in a group box.  The Toolbox in the Windows Phone 7 Toolkit does not have a group box.

I found the solution here: http://social.msdn.microsoft.com/Forums/en/windowsphone7series/thread/89cf0ad0-e4bd-4baf-9532-157c30f3fd81

I was trying to do it programatically, and could not find a simple way to programatically set the state of the Radio Button, trying to use SetValue required a DependencyProperty...
