currently I have used two ways. The first way I use a popup dialog or DAP
with a click link to feed the parameter to the second page which uses a
group filter control. I have only used the filter for single parameters but
I would imagine you could send more than one parameter for the filter. I am
not programmer by nature so I'm not sure.
The second way is use a popup or DAP to get the parameters then write the
query based on those parameters (i.e. use a client side query rather than
server side). while client side queries are slower, this may not be a big
deal if the data set is small or time is not that critical. Let me know
which way you are interested in.
