The reason I asked was that I got an error when I used all 4 js file

I think the problem is that some of functionality in infragistics.reporting.js is also

in the other js files, but I replace the infragistics.reporting.js with infragistics.ui.reportviewer.js

and there was no more errors

Hello Christian,

 Thank you for the reply.

 You need to manually reference several resources for the Report Viewer to work, including the Infragistics theme, Reporting structural CSS files, and the base JavaScript files, and infragistics.ui.reportviewer.js is from the reporting base scripts. The first reference that I send you describe that in more details.

 I am glad that you have managed to resolve your issue! If you have any other questions, contact me.
