Datagrid Paging loses input data

[joedivec]

I have an aspx page that is split into 2 panels: Input and Output.
The Input panel consists of about 10 text boxes and the output panel
is built from these input parameters.

When you click submit on the Input panel, I make it invisible and make
the output panel visible. The output is fine. However, when I go to
page through the output (which is in a datagrid), I have lost my input
parameters.

Do I have to explicitly save these off in ViewState, Session, or
something? Or is there a slicker new ASP.NET way to do this? I know
I can get it to work with querystrings, cookies, or something, but I
want to know if I am missing something before I do all of this coding.

Thanks.
