Ignore RowValidating Event when UI prepares for viewport

[Anon]

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?

Hi Matthias,

With the latest version of the UI for WPF controls it is not possible to avoid having the RowValidating event thrown when rows are prepared. That said, we have introduced the None value of the EditOperationType property of the event arguments. If you want to skip the event in that scenario, you can perform a check for that value and avoid performing any action. 

I hope you find this helpful.
