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.

Amelyan,

It sounds like one alternative would be to create two separate radio
button lists.  You would set both of the 'AutoPostBack' properties
to be true.  From here, you could programmatically check to see if a
value is selected in either of the radio button lists in the
SelectedIndexChanged method.

For instance, if something is selected in RadioList1, make sure that
there are no selections in RadioList2 and vice versa.

I am not quite sure why you are using the two separate lists as one, as
their might be a better way.  Could you provide an example of what you
are attempting to do?  From what you have described, it almost sounds
as if you would simply want one large group.

The above option is simply a suggestion and there might be several
other alternatives that may accomplish what you desire.

I hope this helps,
Aaron

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

I am aware of the post back alternative.  However, in my case it is not
a good solution.  What I am looking for is a non-postBack solution.  I
want to accomplish similar behavior with Two groups as already exists
with one.

Thanks,
Amelyan
