Crystal Report viewer navigation buttons not working

Question

User-1066573097 posted

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.

Does anyone have suggestions for a solution?

Where is Page_Init() in Visual Studio 2008?

 Thanks for any help.

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).

Hope it helps someone.

 did you call report binding inside Not Page.IsPostBack ? like

        If Not Page.IsPostBack Then
            'call report
        End If

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.

Thanx man, it helped me a lot too...

the sample code in C# is something like so...

 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;
            }
       }
