Hi Sam,

Thanks for your reply.

As of now, I actually prefer to utilize what I know on .NET and what I am 
learning on Flex. Adding another utility (Web Orb) in my learning process may 
complicate things a bit.  I might consult this later if I feel that the needs 
for is getting tremendous.

Anyway, I am actually able to generate the report from what I am currently 
doing (no error encountered), where the ArrayCollection I am parsing into a 
delimited string, passing the string to the webservice call, and letting the 
webservice de-serialize the string to populate a Crystal report document which 
I subsequentlt display in another browser window which I call from the Flex 
application.

I mentioned that I did not feel it is the "BEST" way because I am literally 
storing all datagrid (report) information in a string variable.  Assuming for 
example that the data displayed in the datagrid is quite huge, then creating 
the delimited string would take some time and additional processing time could 
also be consumbed by the back end web service to parse the string and populate 
the report.

As of now, this is what the application does.
1. Flex App calls a webservice to retrieve data.
2. WebService responds by sending back a dataset which is returned as a string 
(via Dataset.GetXML method of .NET).
3. Flex App gets the service response, converts the string into an XML.
4. Flex App converts the XML data into an ArrayCollection which is bound to the 
datagrid.
* Please note that I used array collection here for the search/filter 
functionality of the datagrid.
5. When generating print out of the data displayed in the datagrid, Flex would 
then serialize the ArrayCollection into a delimited string and send it to the 
web service.
6. Web Service would then de-serialize (or parse) the string, populate a .NET 
dataset which is the datasource for the Crystal report.
7. Crystal report is bound and PDF report is generated.
8. Flex displays via external javascript call the PDF report generated.

Is there a better way for the ArrayCollection to be sent to the webservice, the 
webservice in turn would just convert it to dataset and the dataset is 
immediately bound to the Crystal report?  

Thanks.

Regards,

Angelo

I'd say XML would be a good way of doing it. What kind of errors are
you getting, and how are you making the web service call?

The other option is to use AMF, a native messaging format for
Flash/Flex. This I believe would save you the effort of serializing
and deserializing - it does it for you, among other things.
