I use crystal report 9 with VS.Net 2003. I load crystal report to the web form. but I have a problem on next button.

if I click next, it goes to 2 page, but when I click next again, it is still in 2 page, never can pass page 2. But I can go to last page. If I click previous button, it always goes to 1 page. why it happen? and how can I fix this problem. if I put set parameters in !Ispostback block, when I click next, I got missing parameter value error.

 I am very appreciated if anyone can give me some hints. Thanks!

You probably need to put the code that binds CrystalReportViewer.ReportSource into the Page_Init event handler rather than the Page_Load event handler.

For an explanation why, see:

I'm having the same problem with my crystal report. Did you end up getting it fixed and what exactly did you do? I looked at the linked that was given but it was sort of confusing for me.

Never mind, I got it working. Thanks David! I did exactly what you told me and it worked.

Sorry for the complexity; it's an unfortunate byproduct of the way ViewState works with the Page events, Init and Load...
