Hi Anderson,
Thank you for writing.
I was not able to reproduce such an issue. I set the
HorizontalScrollState property to
ScrollState.AlwaysHide and then edited the grid and changed values of cells through code but the event was fired every time it is supposed to. If you are setting the value of a cell to the same value it has, the event will not be fired as no change occurs. If you are able to reproduce the issue in a sample project send it so I can investigate it.
I am looking forward to your reply.
Kind regards,
Ivan Petrov
