Checkbox items under a RadioButton

I have to have three RadioButtons and then under one of this RadioButton, I
need to put two checkboxes. Something like following:

O Temperature
[] Air
[] Water
O Radiaton
O Wind Velocity

The child CheckBoxes (Air and Water in above example) should become
"activated" only when the parent RadioButton (Temperature in above example)
is selected. I am just confused how to get this done.

Any example in this regard will be gratefully appreciated.

you can have the page postback by setting AutoPostBack="true" and
OnSelectedIndexChanged="rdo_SelectedIndexChanged"

in the server side function rdo_SelectedIndexChanged check the current value
of the radiobutton and then set the Enabled property of the checkbox to true
or false

Aha ! I got the idea now. I tried and it works fine.
I run into another design problem. The "entire form" is posted back, which I
do not want.

How can I have only these two controls posted back? Any idea or any URLs for
me to read?

Yes, that's the standard way, you could use ATLAS to have Ajax
functionality.

You could do some manipulations in the client page using javascript , IMO it
will solve your problem fine. Add a client side handled for the checked of
the radiobutton and inside it disable/enable the checkboxes.

Any example, tutorial on the web ?
or even page of a book that I should refer for such tasks?

Thanks,

Hi,
You can do this easily with Java Script. You need to add attribute eg:
rdBtn1.attributes.add("onclick", "changeStatus()")

Then in that changeStatus function, capture all the check boxes under
that category and enable/disable them.
We can pick all the check boxes by using some common naming convention
or by using table1.getElementById('xx.').all.tags("INPUT") where table1
is the table which contains all the check boxes under that radio
button.

OK..
