Have a table with the first column being option buttons. A user clicks on
one to identify the row of data they want. What I want to do is once they
pick a row to then identify the value in the third cell on the row they chose.
I know this can be done using a loop.
(The table is dynamically built using ASP so when the option button TD is
built, an onClick event is added to the code.)

Can you identify the specific row and gets a cells value without going thru
a loop and checking each row until you find the checked one? Sometimes the
table could have a large number of rows and there's too much delay waiting
for it loop.

Could the onClick event be used?

Thanks for any help.
