'Microsoft.ReportViewer.ProcessingObjectModel

Hi,

I get the following error.

An error occurred during local report processing.
The definition of the report 'Main Report' is invalid.
An unexpected error occurred in Report Processing.
Could not load file or assembly 'Microsoft.ReportViewer.ProcessingObjectModel, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.


any clue to solve the issue?

Your application is trying to look for the component Report Viewer version 8. We only have either version 9 or 10 installed on the servers GAC. Try uploading the version 8 in your applications Bin folder so your web application can reference it or update your code to use Report Viewer version 9 or 10.

 

Thanks Ray,

Will check and let you know if this solves my issue .

Cheers,

quick one

Hi Ray,

I tried to replicate in my system . i was able to do it. i overcome the problem using the setting

In IIS 7, we need to make sure we configurate the ReportViewer handler.

You can follow these steps:

o Open Internet Information Services (IIS) Manager and select your Web application.

o Under IIS area, double-click on Handler Mappings icon.

o At the Action pane on your right, click on Add Managed Handler.

o At the Add Managed Handler dialog, enter the following:
Request path: Reserved.ReportViewerWebControl.axd
Type: Microsoft.Reporting.WebForms.HttpHandler
Name: Reserved-ReportViewerWebControl-axd

o Click OK.

We just created a KB Article with instructions on how to perform this fix in our environment.

It is very similar to Silay's post, but at least now customers can find it with ease in our support portal.
