Hello David,

In the provided configuration file I cannot see Telerik.ReportViewer.axd handlers registrations in both system.web and system.webServer sections. Please compare your settings to these in How to: Add report viewer to a web page. If needed run the Upgrade Wizard in all projects having references to Telerik Reporting.

In addition check the deployed files and the Bin folder for an older assembly of Telerik Reporting (check the files properties and if any is of version 4.1.10.714 - the specified in the error).

Hello...thanks for your information.....I already added in my Webconfig file the next reference in the "<system.webServer>"  section:

<handlers>
<add name="Telerik.ReportViewer.axd_*" path="Telerik.ReportViewer.axd" verb="*" type="Telerik.ReportViewer.WebForms.HttpHandler, Telerik.ReportViewer.WebForms, Version=x.x.x.x, Culture=neutral, PublicKeyToken=a9d7983dfcc261be" preCondition="integratedMode"/>
</handlers>

But the problem persist......to try the second sugestion.....where may I find o download the "older assembly of Telerik Reporting (version 4.1.10.714)"............to put it on my bin folder?

 Thanks!...........please help?

 

PD. is there any way telerik develop components that are self-contained ? .... ie .... that you do not have to be adding things from elsewhere to work?.... it is just an idea....because it is very common these kind of problems

Hello David,

If you are using a greater version of Telerik Reporting than 4.1.10.714, you should not add the older assembly in the project's Bin folder.

Instead clear the Bin folder content and re-add all Telerik Reporting assemblies (Deploying Web Applications). Then run the Upgrade Wizard in all projects having references to Telerik Reporting (reports and viewers' projects) to verify they are using the same version. On adding a reference to an assembly set its CopyLocal to true in VS.

When you check the settings of the viewer, make sure the X.X.X.X from the examples are substituted with the actual version of the referenced Telerik Reporting assemblies.


On a side note, adding the viewer per How to: Add report viewer to a web page, will add automatically references and configurations in the project. Still in your case the issue is related to loading an old assembly left in the project's bin folder or a reference to it.
