Problem using radiobuttons in a datagrid

Hi,
I need to implement the following requirement. I need to populate a datagrid from the database using a straightforward query.
One of the fields say X retrieved from the DB should not be shown on the grid, but must be brought to the clientside.
In addition to the fields returned from the DB, I need to have a radiobutton column. When I click on any radio button, I need to show the contents of the field X in a separate textbox mentioned earlier using clientside JavaScript with no postback.

I tried implementing this using a template column for the radiobutton and the remaining fields being autogenerated at run time.
But, I cannot select any radiobutton, on clicking, they remain unselected. Also, I have no idea as to how to display the value in the textbox

I am stuck and would appreciate some help.

Thanks in advance.

I'm looking to do the same thing here. Had any comments ?
