I have a puzzling "issue" that I am trying to help track down or better understand. I have one user who can readily recreate an issue where no tool bar buttons display on a ReportView control on a page that uses a ReportViewer to display a report. Everyone else on our team is unable to recreate the issue. But, to do my due diligence I am doing research to see if I can maybe understand why that user may be having the issue and to try and make sure it doesn't become an entire user base issue. If all of us could recreate the issue I would open a ticket, but with that not being the case I am just looking for some help.
ASP.Net AJAX Web Forms
Steps the one user does to consistently create issue:
1. In IE 11 go to one page that has a report that renders via the ReportViewer.
2. Go to a second page that has a report that renders via the ReportViewer.
3. Go to a third page that has a report that renders via the ReportViewer.
The report renders, but the tool bar show no buttons.
In the IE console the user see an error "@font-face failed cross-origin request. Resource access is restricted. WebComponentsIcons-eot"
While I am unable to recreate the issue, via Fiddler I do see some interesting 404 responses when the pages with the ReportViewer control on them load. All of the following requests get 404 responses via IE 11.404 HTTP our-domain /OurApp/fonts/glyphs/WebComponentsIcons.eot?gedxeo 1,245 text/html iexplore:19312
404 HTTP ourt-domain /OurApp/fonts/glyphs/WebComponentsIcons.ttf?gedxeo 1,245 text/html iexplore:19312
404 HTTP our-domain /OurApp/fonts/glyphs/WebComponentsIcons.woff?gedxeo 1,245 text/html iexplore:19312
Another interesting thing is that via Chrome in Fiddler there are 404 responses for only the last two (tff and woff) and never even see a request for the eot.
Again, I do not have the issue with the missing icons in the tool bar of the report viewer, but I seems odd as I get 404s for WebComponentsIcons.
Any help trouble shooting this would be greatly appreciated. Thanks!
