I also am having a problem with the ReportViewer not working after having moved my project into VS2010 and .NET 4.0.  The ReportViewer shows no data for my drop down controls and no chart.  I have added the <handler> to web.config that I found in another post:
<system.webServer> 
    <handlers> 
      <add name="Telerik.ReportViewer.axd_*" path="Telerik.ReportViewer.axd" verb="*" type="Telerik.ReportViewer.WebForms.HttpHandler, Telerik.ReportViewer.WebForms, Version=4.0.10.317, Culture=neutral, PublicKeyToken=a9d7983dfcc261be" preCondition="integratedMode,runtimeVersionv4.0" /> 
    </handlers> 
    <validation validateIntegratedModeConfiguration="false" /> 
</system.webServer> 

I am currently running Telerik Reporting Q3 2008 SP2 (v2.9.9.202).  Would updating to a newer version help?
Thanks.  Dan

Hi Dan,

The information you have provided is insufficient for us to determine what might be the problem. And when you say "I also am having a problem", we assume that you have read upon a similar thread in the forums - we try to answer all forum inquiries just like this one and surely we have suggested what might be wrong based on the details provided by the user?
Quite frankly v.Q3 SP2 2008 is more than an year old and we can only guess what you've hit. Generally the first version in which we have announced compatibility with VS2010 is Q1 2010, so you would have problem working with the report designer in VS2010 with that older version. Otherwise, the framework change should not have that much impact as we're still compiling against .NET2.0 and the only change required for the web viewer is the preCondition attribute which you've already changed.

Kind regards,
Steve

I have upgraded to Telerik Reporting Q1 2010 in VS2010 for my .NET 4.0 projects.  This has let to other problems, and so I entered a different forum thread '2 Reporting versions in GAC'.
