Telerik Reporting and IIS

[Gosha]

I created report using Class Library, copy connection string from app.config to web.config, on web site add reference to Class Library and add control ReportViewer, set Report property and run solution. When run with ASP.NET Development Server report looks normal and data is displayed. But when I run web site directly from IIS, ReportView control is not showing correctly (see pictures). 

Files for web site is in c:\inetpub\wwwroot\sitename

in c:\inetpub\wwwroot\sitename\bin is dll, pdb and xml from ReportClassLibrary

Class Library project is elsewhere but within same solution.

Why ReportViewer is normally shown on Developer Server and VS Designer preview but on IIS is not working?

A used almost every control from ASP.NET AJAX controls and they looks identical on IIS and Development server.

Hi Sasa,

Take a look at the following KB article for more information on your inquiry: The styles of the web report viewer's toolbar are messed up.

Kind regards,

In web.config I replaced preCondition="integratedMode,runtimeVersionv2.0" with preCondition="integratedMode" and now is working. But how could I know that?

Thanks anyway.

Hello Sasa,

This is how the http handler was registered in versions prior to Q2 2010, but with the release of .NET 4 we had to change its registration and it would be correct once you upgrade to a more recent Telerik Reporting version.
