Our QA team reported that one of our applications is not working in Safari in Windows 7. After checking the problem we figured out that any postback event is not working. After some tries we found that Page.IsPostback() reports false and thinks it’s a first-time load of the page and postback did not include ViewState.
We tried many solutions including
ASP.Net postback problem with ViewState in Safari on Windows 7
Viewstate invalid when using Safari
ViewState Chunking in ASP.NET 2.0 (maxPageStateFieldLength)
but all didn't bring Safari to work.
There is nothing special about this application. It is normal pages that use one master page that is a very normal master page.
Any suggestions?
