I am working in vb.net, visual studio 2008, with the crystal reports that comes with it. I have a push model: creating a dataset, putting data into it, making that a report source, and putting the report source onto (or into) a crystal reports viewer control (not neccessarily in that order). It works -- for the first page that's displayed.
That report has two pages. If I click on the control to go to the 2nd page (where I have no data displayed yet), then on the control to come back to the first page, it displays with no data -- just the background text is there.
I can see my dataset-loading code executing in the debugger, and as near as I can tell the database is no longer giving me back any data.
I think this used to work; can't imagine what I changed to cause this problem.
Can someone point me in a direction to look to debug this? I've tried rebooting the computer (in case I was out of connections or something). The SqlServer and database are on my local machine, it isn't a connectivity problem.
