crystal report is not showing any data
Question
I am new to crystal reports. But i have designed the one crystal report by using help from google and asp.net forum. But after doing all the coding i am not able to view the crystal report after running through visual studio 2010. development environment (windows-7 32 bit,visual studio 2010 ,Crystal report V.13). My aspx looks like below:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="ReportSapco.aspx.cs" Inherits="ReportSapco" %> <%@ Register Assembly="CrystalDecisions.Web, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" Namespace="CrystalDecisions.Web" TagPrefix="CR" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head id="Head1" runat="server"> <title></title> <link href="8LcKSBVeHKaZoXGjmWViuQ==/Site.css" rel="stylesheet" type="text/css" /> </head> <body style="background-color:#E6E6FA;"> <form id="form1" runat="server"> <CR:CrystalReportSource ID="CrystalReportSource1" runat="server"> <Report FileName="CertsReportSapco.rpt"> </Report> </CR:CrystalReportSource> <div> <CR:CrystalReportViewer ID="ReportViewer" runat="server" GroupTreeImagesFolderUrl="" Height="1269px" ToolbarImagesFolderUrl="" ToolPanelWidth="120px" Width="100%" EnableDatabaseLogonPrompt="False" EnableParameterPrompt="False" HasCrystalLogo="false" hasToggleGroupTreeButton="false" BestFitPage="false" ToolPanelView="None" BorderColor="#006699" BorderStyle="Solid" BorderWidth="2px" HasToggleParameterPanelButton="False" ReuseParameterValuesOnRefresh="True" HasSearchButton="False" onload="ReportViewer_Load" ReportSourceID="CrystalReportSource1" onunload="ReportViewer_Unload" /> </div> </form> </body> </html>

I debugged my code and i found that i am getting below error:
HasRecords = Function evaluation disabled because a previous function evaluation timed out. You must continue execution to reenable function evaluation crystal reports
I am getting this error for all the attributes after HasRecords for the ReportDocument.
I googled and found that something is going in infinite loop or all breakpoints should be removed to solve this error.
But to my observation nothing is in infinite loop for the above mentioned code and I removed all the breakpoints but no luck.
Will anyone help me to solve this error i am not able to see crystal report after running the code.
I am getting blank page and getting this error For ReportDocument.
I set "PrintJobLimit" PROPERTY in registry = 250 and Enable 32-Applications on Application Pool in IIS = True

The reasons of the hang and of this error message are probably the same: there is something that takes a lot of time to compute. Both when you do it in code and in debugger.
It seems this kind of bug can happen simply when you are trying to watch at some variables who have to be thread safe but sometimes this framework implementation is not perfect....
In this case "HasRecords" doesn't appear in the code, so I suppose that it is watch window that causes the problem.
To avoid this problem : when stepping through code where variables are bound to windows or other controls, you don't show local variables or "auto" variables. Look at such things only when you are sure your variables are all safe to look at. And note that the error doesn't necessarily appear on the unsafe variables. Use the "immediate" window on safe (ie non-control) variables when operating in dangerous code.

Solution
1. step one
The solution is to work on IIS this way:
- Copy
aspnet_clientfolder fromc:\\inetpub\\wwwrootfolder to the new website root folder.
or (first one is easier, second one is better for maintenance)
- Create a virtual directory called
aspnet_clientthat points to
c:\\inetpub\\wwwroot\\aspnet_clientinside the new website
2. step two
copy this below to your web.config
1.
<configSections> <sectionGroup name="businessObjects"> <sectionGroup name="crystalReports"> <section name="rptBuildProvider" type="CrystalDecisions.Shared.RptBuildProviderHandler, CrystalDecisions.Shared, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304, Custom=null" /> <section name="crystalReportViewer" type="System.Configuration.NameValueSectionHandler" /> </sectionGroup> </sectionGroup> </configSections>
2.
<businessObjects> <crystalReports> <rptBuildProvider> <add embedRptInResource="true" /> </rptBuildProvider> <crystalReportViewer> <add key="ResourceUri" value="/crystalreportviewers13" /> </crystalReportViewer> </crystalReports> </businessObjects>
3. step three
Add this reference to the crystal report javascript in your master page or page rendering the report:
<script src='<%=ResolveUrl("~/crystalreportviewers13/js/crviewer/crv.js")%>'type="text/javascript"></script>
