hi,
i am developing web application using c#.
in a particular page i am using two drop down list boxes, one for
product and the other for corresponding models of a product. whenever i
select a product the corresponding models will be populated in the
model drop down list. and i am using ajax for populating the model ddl.
hence the model ddl will be populated at the client. now when i do my
processing using the datum in the page i am getting the error
object reference not set to an instance of an object.
i think i am not able to read data at server which is populated at
client.
what is the solution fot this problem?
