With the release 2020.1.115 the following changes were made:
The RowValidating event is now fired when the UI virtualization prepares a row to be shown in the viewport. There is a new value in the GridViewEditOperationType enum - None for this specific case.
I need the behaviour before this release. So when UI virtualization prepares a row to be shown in the viewport the validation should not take place. Only when a cell was edited / changed. I need the ValidationResults which are not provided in RowEditEnded Event.
What do I have to change in this case?
