Hi gowthamtr,
That is an information I can give you without some more information on what you are doing.
But I presume you could send to the previous page some information on the selected values, and then pre-load the selects and pre-select the correct values when generating the page.
That's what I've done in the past, in similar events.
An alternative is to have a javascript that calls the same methods that were called as eventHandlers.
