I have created a report in the standalone designer and it previews just fine.  When I try to display the report on an ..aspx web page in a Visual Studio 2012 web application, I receive errors on every item on the report viewer (all buttons and the ReportViewer itself).

I have attached a screen capture of the displayed page + the error dialog box (DisplayedPage1.png).  I have also attached a screen capture of the actual javascript error line (DisplayedPage2.png), and a screen capture of the Visual Studio project including the .aspx html page.  There is no code at all in the code-behind file.  I have also attached the Fiddler screen capture which shows that nothing related to the Report Viewer is found when the page is displayed.

The web.config file source code is included below.  The report uses the AdventureWorks database and produces a simple listing of the products in the database.

This is my first attempt at using Telerik Reporting, so I've probably done something stupid, but I need some help, please and thank you.

Stef,

I appreciate your comments, but I resolved this a couple of hours ago.  Your suggested readings are not particularly helpful.  I found these same readings while trying to debug the problem, but following the instructions contained within did NOT resolve the problem.

Telerik should be aware that the contents of the web.config file AS CREATED BY YOUR VISUAL STUDIO TEMPLATES, are not entirely correct depending upon the type of project being created.  I have VS2012, am using .net 4.5, and had to add additional lines of code to get the report viewer recognized on the page by .net.

Thank you for your intended assistance.

Hello Lynn,

I am sorry to hear you are having bad times configuring Telerik Reporting. Adding the ReportViewer as described in the help article should have registered all needed handlers.

Can you share, which parts did you have to add manually?
