hi,

i also had the same issue..

thanks for your reply.. now i could rectify it..

but now another issue i have..

i am using one dataset to populate a dropdown list which selecteditem is the input to second dataset..

and i have 3rd dataset which is dependant on 2nd dataset selected parameter..

if i select a particular item from the 1st dataset(dropdown list), i will not populate the 2nd dropdownlist(no o/p from 2nd dataset) .. but the 3rd data set does not require the 2nd dataset o/p to actually produce the output ie, that field can be null...

but this feature iam not able to implement ..

pls help ...

Thanks in advans........
