Working in Visual Studio 2008 and using the packaged Cystal Reports (version 10.5). I have a couple pages that use the Crystal Reports Viewer to display the reports, and I use the CRV navigation buttons to page through large reports.
Problem: The Next button only goes to page 2. The Previous button goes to Page 1 every time.
I've read that this is because the binding of the report occurs in the Page_Load() and the CRV paging resets every time the report is rebinded. It was suggested to move this into Page_Init() which should only fire once, save the report in Session state,
and then rebind on post backs. I've tried this, but my code never seems to reach the Page_Init(). In fact, I don't even see Page_Init() as an option. I've tried protected override OnInit(), but it fires every post back so that's no good.
OK, I found the Page_Init() issue...I manually add the event, but I forgot to wire it up in the InitializeCompnent() with this.Init += new System.EventHandler(this.Page_Init).
Now I'll see if I can get the nav buttons working by moving the report binding into there....
OK, it took some fiddling, but moving the code to Page_Init() seems to work. Now I can navigate correctly.
To recap, I was getting my dataset, binding it to the report, and binding the report to the viewer, all in Page_Load. I moved that to Page_Init() and the viewer's navigation buttons work (Next and Previous specifically).
i ve put all of binding logic in page_init method but haven't got desired results. i.e. i can come from page 1 to 2 but not on page 3 by hitting next button. kindly if u can help me out by some sample code/Reference.
I was facing the same issue. I resolved my issue by Turning the View State on. In my case the view state was turned off for all pages of the website using the web.config.

protected void Page_Init(object sender, EventArgs e)

if (!IsPostBack)
{
// do all your reporting stuff here, then add it to session like so
ReportDocument crystalReportDocument = new ReportDocumment();
crystalReportDocument.SetDataSource(DataTableHere);
//_reportViewer is the crystalviewer which you have on ur aspx form
_reportViewer.ReportSource = crystalReportDocument;
Session["ReportDocument"] = crystalReportDocument;
}
else
{
ReportDocument doc = (ReportDocument)Session["ReportDocument"];
_reportViewer.ReportSource = doc;
}
}

Crystal Report viewer navigation buttons not working

Does anyone have suggestions for a solution?
Where is Page_Init() in Visual Studio 2008?
Thanks for any help.
