set enable/disable in client side.

[Paul]

Hi,

I have a ajax Grid, and some template columns. 
I want to enable/disable other column if I change the combobox value. How can I do that?
How can I get the client_id of another Grid template item control?
I had try to add a literal control in javascript client side,  but the literal control can not updated because of Ajax.
How can I make this? please help. thanks.

Regards,
Paul.
