1984338 - Crystal Report in a web viewer not paging past first or second page

Symptom

  • Using the Crystal Reports SDK for Visual Studio .NET.
  • The report's first page displays as expected.
  • Paging to second or third page of a multipage report fails.
  • No errors are thrown, but page does not change.
  • Additionally, when a page number is manually entered (e.g.; page 6), the report will display the page, but paging back, the viewer displays page 1.

Environment

  • SAP Crystal Reports, developer version for Microsoft Visual Studio
  • Microsoft Visual Studio 2010 / 2012

Cause

  • The report viewer code was in the Page_Load event:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load


    CrystalReportViewer1.ReportSource = "C:\tests\formulas.rpt"




End Sub






Resolution



   
    

  • Perform the report viweing at Page_Init:
    • 



Private Sub WebForm1_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
 
       

      CrystalReportViewer1.ReportSource = "C:\tests\formulas.rpt"


End Sub
