Web ReportViewer Error

[Philip]

I am trying to publish my first Telerik Report to the web. I can display the report when I run it in my development environment. However, when I publish it, I get the following error. (The first error I got told me to insert this     

<add verb="*" path="Telerik.ReportViewer.axd" type = "Telerik.ReportViewer.WebForms.HttpHandler, Telerik.ReportViewer.WebForms, Version=3.2.9.1211, Culture=neutral, PublicKeyToken=a9d7983dfcc261be" />
Line 48: </httpHandlers>
Line 49: <httpModules> ,

and then it says it cant find it.) If I delete it, it tells me to insert it. If I insert it, it says it cant find it. Any ideas?

Hello Philip,

The original warning you receive explains that you should register the handler for the web report viewer in the httphandlers section in the web config. However if you're hosting the application in IIS7, there is a different section to add the handler to, namely the <system.webServer>\<handlers> section:

<system.webServer>
    <handlers>
       <add name="Telerik.ReportViewer.axd_*" path="Telerik.ReportViewer.axd" verb="*" type="Telerik.ReportViewer.WebForms.HttpHandler, Telerik.ReportViewer.WebForms, Version=3.2.9.1211, Culture=neutral, PublicKeyToken=a9d7983dfcc261be" preCondition="integratedMode,runtimeVersionv2.0"   />
    </handlers>
    <validation validateIntegratedModeConfiguration="false" />
</system.webServer>

Generally you should not have to make these modifications manually since adding a report viewer to your web site/app automatically adds the necessary registration. The problem in your case is probably due to the fact that you have not uploaded your entire project to the server, otherwise the web.config from your project would have those registrations present. You can copy that web.config and see if that makes a difference, just in case I have attached a working web.config for your convenience.
As for the second error - it clearly states that it cannot find a necessary assembly you're referencing. During the installation of Telerik Reporting on your machine, the Telerik assemblies were added to GAC. When deploying a Web Site project the assemblies from the GAC are not copied automatically, so you need to copy the assemblies manually from the installation’s Telerik Reporting /bin folder to the bin folder of your application on the server. Full step by step instructions on deploying are included in the Deploying Applications using Telerik Reporting help article.

All the best,
Steve

Hello

When I tried to deploy one of my websites I got the following error message. But I have included all the necessary dll files in the assembly section of the web config file. I have also included the handlers in the appropriate section of the web config file. What else should I do to resolve this error message?

Thanks,
Deepa

When I had the same issue, I had not loaded the Telerik Reporting on the Server that I was deploying the application to. Once I loaded TR on the server, it registered the items in the GAC and my issue was resolved. I had the software loaded on the development machine, but not the server.

Hope this helps.

Hello Philip,

Thanks for the quick response. I will try that.

Hi Steve,

Hi Dhruv,

Philip has already provided insight as to what the problem is in his post from Jun 25, 2010, namely you have not deployed the project correctly. More info is available in the Deploying Web Site help article.

All the best,

Hi,

The Telerik Team clearly tells you to "copy the assemblies manually from the installation’s Telerik Reporting /bin folder to the bin folder of your application on the server"

To automate this process, under your project Reference, right click on Telerik.ReportViewer.WebForms and click Properties. Make sure that the Copy Local property is set to True. And do the same for the Telerik.Reporting reference.

It's quite handy!
