I have developed a ASP.NET Web Application using the CR.NET 2008 Basic (10.5.3700.0). runtime.  I am ready to use the full version of Crystal Reports 2008 so I installed the Developers Edition.  

I have upgraded the reports/solution using the automatic tool see attached screenshot: Crystal_Reports_2008_Solution_Conversion.png.   The Business Objects Visual Studio Integration Manager tool shows that I am using the full runtime (12.0.2000.0).

The application compiles and runs fine.   However when I load a report a into the CrystalReportViewer the first time I receive the error:

Value cannot be null.  Parameter name: inputString

The second time the report viewer is empty (blank) no error.  I have scoured my code and the report itself and I can not find the parameter/variable inputString.   Now development started in 2007 in Visual Studio 2005 with VB.NET and over the years has been migrated to C# in Visual Studio 2008.   The reports however were always targetting the CR.NET Basic runtime.  I need the full version to utilize the royalty free Developer's Advantage license from SAP.

I am including screenshots to illustrate the report working and not working.

I can change the assembly references in the web.config from 12.0.2000.0 back to 10.5.3700.0 and the report shows up correctly again.

  I don't follow do you mean as references?   I am attaching a screenshot of my project's references which do list 12.0.2000.0.   I did change my setup projects prerequisites to look for/install Crystal Reports 2008 full runtime but this problem is occurring during debug mode on my development PC.

   I am including the markup code from the Master Page that hosts the CrystalReportsViewer.  I use a tag prefix so I am including the appropriate lines from the web.config.   The first defines the tag while the second as previously established determines the assembly reference.
// ASPX Page Markup
<crystalReports:CrystalReportViewer ID="crystalViewer" runat="server" AutoDataBind="true"/>
 
// Web.Config
<add tagPrefix="crystalReports" namespace="CrystalDecisions.Web" assembly="CrystalDecisions.Web"/>
 
<add assembly="CrystalDecisions.Web, Version=12.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"/>

Looks good but I am not a web/ASP person.

If it is getting the viewer from the VS2008 assembly, that is based on CR10 and doesn't support optional parameters.

I have used CR2008 with an application so I wasn't aware of that.
