We have a WFP app (no source code) that hosts SSRS reports in a separate window. The window has several buttons and registers at least one event (determined because of the error message). It all worked fine on SSRS 2014, we upgraded to get away from the print driver requirement. In our environment the print driver distribution is troublesome. End users are not local admins.
When the report page opens we receive 2 errors and then the standard Prev, Next, print buttons are not displayed.
Errors are
Object doesn't support property or method "addEventListener" Code 0 URL http://SSRSServer/ReportServer_SSRS2016/Reserved.ReportViewerWebControl.axd?OpType=Resource&Version=13.0.1601.5&Name=Microsoft.ReportingServices.Rendering.HtmlRenderer.RendererResources.jquery.min.js
Then
'jQuery' is undefined Code 0 URL http://SSRSServer/ReportServer_SSRS2016/Reserved.ReportViewerWebControl.axd?OpType=Resource&Version=13.0.1601.5&Name=Microsoft.ReportingServices.Rendering.HtmlRenderer.RendererResources.jqueryui.min.js
Things to note. The report opens perfectly if the url is pasted into an IE 11 address bar.
And the server host both SSRS 2014 and 2016 native mode side by side.
Thanks in advance
