Hi Julie,
The CurrentCellValidating event is fired when the user tries to leave the current cell.
I was not able to reproduce the issue that you have mentioned here.
Also I have created a simple sample to test this issue and it is available in the following link.
http://websamples.syncfusion.com/samples/Grid.Windows/F67307/main.htmIn this sample, the CurrentCellValidating event gets fired when we leave the GridCell in edit mode and click the Save button.
Please have a look at the above sample and if still the issue exists, could you please try reproducing it in the above sample or send us the reproducing steps so that we could sort out the cause of the issue and provide you a solution?
Could you also please let us know the Essential Studio version in which you are facing this issue?
Also please let me know if you have any queries.
Thanks & Regards,
Ramya.
