When we want radio button to belong to a group name we say,
radio1.GroupName="GroupA". In this case, radio1 will be unselected if
another radio button is selected in "GroupA".

Is there a way (trick, or javascript) to make radio button (radio1) belong
to 2 independent radio button groups instead of one? This would be an
equivalent of sayting something like
radio1.GroupName1 = "GroupA";
radio1.GroupName2 = "GroupB";

Hence, whenever radio button is selected in one of the two groups, radio1 is
unselected. Also, I need a non-postBack solution.


Thanks,

PS> Example of what I need to accomplish:

Imagine that you have a matrix/grid of radio buttons with, for examle,
3 rows and 3 columns.

O O O
O O O
O O O

When you check a radio button in this matrix, you don't want anything
else selected in the same row or column. One neat way to accomplish
this is if there was a way to have radio button belong to two groups,
e.g. "Row2" and "Column2".
