How To Get Values From Table Row When I Select Its Corresponding Radio Button?

Yeah, sure I can. But, first you'll need to flesh-out your question a little more. That is to say, you've provided fewer details than are really needed to answer this question by someone not familiar with your current code.

You should edit/improve your question to include details like:
■ Do the radio-buttons exist in the table or outside of it?
■ Do you want there to be 1 text-box per table row
■ You mention updating the information. Is it your intention to grab data from a table, modify it and then finally, re-insert the data into the table?

There's likely to be other pertinent questions I've not considered, feel free to update your question to include any/all extra information you have. :) The current HTML structure of the table, radio-boxes and text-boxes would all be useful.
