do you get the index variable filled correctly?
Your error means that either that row number doesn't exist on page one or the 2nd column doesn't. Your row command executes after your page load event, did you remember to load the grid again on the right page in your postback load event too?

if (e.commandName.tostring()=="your command name")
{
//do something
}
