When I add RadGrid, the web appears the error message when I switch webpages on my ipad mini : safari error a problem occurred with this webpage so it was reloaded. But android device(SAM SUNG Galaxy Tab4) is all right. Does somebody know how to solve this problem?
This error can be caused by many things. I'm really just guessing without access to the actual code. First, make sure you are updated to the latest iOS. In the past this was a webkit bug; hopefully not resurfacing with iOS 10.1. If you have the chance you could check with 10.2 to see if the error still exists.
If it is happening on several iPhones, everytime, it leads me to the same conclusions you have reached.
1) It is either the webpage using old / deprecated scripts
2) iOS browser bug
