Thanks Michelle,
How could I achieve the second one.I do not like Flashing windows in
response to selection of an item.
I agree the data transfer is very little but the same data transferred for
more than once takes multiple of the initial load time.
I used to use <%....%> in asp to achieve the forbidden method( :) just
kidding) of client side scripting. The Script tags were used to create a
data array with Database data relevent to the page.
Could anyone please tell me the relevent one here.
Thanks
