well, you can use checkboxlist but it doesn't work like radio buttons do. The user will be able to select multiple ones if you choose checkboxes instead of radio buttons. But if you decide to do checkboxes, use javascript to uncheck the other boxes in your group.

Help with Code Tags

(Toggle Plain Text)

<script type="text/javascript">
function selectChkBox(field,checkit)
{
  for (i = 0; i < field.length; i++) {
	field[i].checked = false;
  }
  checkit.checked = true;
}
</script>

then call it with an OnClick event like below:

<label><input type="checkbox" id="chkSelection" name="checkbox3" value="3" onclick="javascript:selectChkBox(document.formname.chkSelection,this.name)" />Checkbox 3</label>

I haven't tested it, but it should work. What it does is set all the checkboxes to unchecked, then checks the corresponding checkbox found by its name. Make sure that all your checkboxes are one ID (that are affected anyway), and then have each one a different name.
