Hello, We have built a VB.net app and this app is using the Microsoft Report viewer 2012 runtime to view report on a local report server. One of the user that accesses the report many time a day is finding that at time the data in the report is not showing on the report. This "missing data" is random and sometime is the bottom of a report, the top of the report, or all of the report. once the user closes and reopens the app, the data returns. Any advice would be appreciated.
