Radio Button in User Control

Hi..
I have user control that has a single radio button.  My page loads the control(s) but depending on the data and loads more than 1 of the same control.. up to 5.  My problem is that after the controls are loaded the radio buttons are not in 'synch'  - I can select multiple values - I need to controls to act like 1 single radio group so only 1 button of the controls can be selected.
Any ideas
thanks

Giving all the radio buttons the same name attribute should group them.

I tried that - I thought it should work too...

    <asp:RadioButton ID="radDEFAULTADDRESS" runat="server" ForeColor="Black" Name="grpAddress" Text="Default Address" TabIndex="-1" />

Actually it shoud be GroupName="grpAddress", but it still does not work because each radio button group name is prefixed with an id, and the id will always be unique. Even if you do not assign a group name, one is automatically rendered for each radio button added via the same user control.

One possibility is to use a standard html input radio button with a group name in the user control. Then upon submit, use javascript to determine which one is checked.
