Our browser navigation (forward, backward) does not function properly when performing a drillthrough action to a subrapport in SSRS rapports after a upgrade/migration.
We used to run SSRS in native mode (SQL Server 2008 R2) as a webpart in sharepoint 2010. We have migrated these reports for a sharepoint 2013 solution running on SQL Server 2012 using SSRS in Sharepoint integrated mode, and showing them as webparts through report viewer.
The problem is that after performing a drillthrough action in a report, hitting the browser back button sends you to the previous page you visited instead of sending you to the previous report. This was not the case before migration. Similarily hitting the forward button sends you back to the page you just left.
