Why I am getting a blank page after publishing Crystal Reports 13 ( Visual Studio 2010 ) to IIS?\
The issue does not occur locally but happens when you host the site on a server in IIS. Actually, the cause of the issue is that Crystal Report is unable to find the required JavaScript (JS) files to render the report in the browser
Solution 1:
1. Please downloading and install runtime for Crystal Reports 13 for Visual Studio 2010. (You can skip this step if you already did this before and your application is working locally).
2. Once the runtime is installed. Crystal Reports will install the required support files in the location of your local computer:
C:\inetpub\wwwroot\aspnet_client\system_web\4_0_30319\crystalreportviewers13
3. Please copy the entire Crystal Report Support folder C:\inetpub\wwwroot\aspnet_client\system_web\4_0_30319\crystalreportviewers13 to your Website's SITE_ROOT\aspnet_client\system_web\4_0_30319 folder.
4) If you do not have a \aspnet_client\system_web\4_0_30319 folder in your website's root. Please create them manually and then copy the crystalreportviewers13 into it.
2. Once the runtime is installed. Crystal Reports will install the required support files in the location of your local computer:
C:\inetpub\wwwroot\aspnet_client\system_web\4_0_30319\crystalreportviewers13
3. Please copy the entire Crystal Report Support folder C:\inetpub\wwwroot\aspnet_client\system_web\4_0_30319\crystalreportviewers13 to your Website's SITE_ROOT\aspnet_client\system_web\4_0_30319 folder.
4) If you do not have a \aspnet_client\system_web\4_0_30319 folder in your website's root. Please create them manually and then copy the crystalreportviewers13 into it.
The version number '4_0_30319' is not fixed, it might be changed because of the asp.net version. You can try to change this folder name to 4_6_1069 if 4_0_30319 not work.
Solution 2:
Add the following code to web.config of the web application.
<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>
<businessObjects>
<crystalReports>
<rptBuildProvider>
<add embedRptInResource="true" />
</rptBuildProvider>
<crystalReportViewer>
<add key="ResourceUri" value="~/crystalreportviewers13" />
</crystalReportViewer>
</crystalReports>
</businessObjects>
