Cache DataSet

[Nikhil Patel]

Hi all,
If I want to access the contents of a DataSet in multiple ASP.Net form
requests without manually saving it in Cache, do I have to add the DataSet
to the form at design time or can I just declare it as Protected and the
Form will save its contents?

Thanks.

Why not add it "manually"?

*if* it is possibly to "have the form save it", then it will be saved in ViewState,
meaning:
- the data will be sent-and-received (roundtrip!) with the html that goes to the browser
- other requests / pages / sessions will still need their own copy

viewstate has "postback scope", the browser needs to send it back to the server.
cache has application scope, every user can access the same data.
