Crystal Report for Visual Studio.NET 2003 in ASP.NET ShowLastPage error.

[Gunady]

Iam using CrystalReport for Visual Studio.Net 2003:
* I have used CrystalReportWebViewer in my web app. I want to make my custom
navigation page that have four button (first, prev, next, and last). I'm
success to use CrystalReportWebViewer's methods like ShowFirstPage,
ShowPreviousPage, ShowNextPage.
But when i used ShowLastPage, i got error :

Missing parameter field current value.

Exception Details:
CrystalDecisions.CrystalReports.Engine.ParameterFieldCurrentValueException:
Missing parameter field current value.

* Does anybody know how to get total page number of one
CrystalReportDoc/Viewer?

* When i zoom CrystalReportWebViewer to more than 100%, it seems strange,
CrystalReportWebViewer displays it in frame/div that has size fit to 100%,
how can i make it displays in full width/height with current zoom (don't
show scrollbar in CrystalReportWebViewer).

* When i export to excel, it's messed up (especially in complicated table,
like group column etc.). Anybody knows how to fix it? (It's ok in PDF or
Doc).

Thanks.
