This appears to be a bug. There is no purpose in the RowValidating during form load, before anything has been entered, and it really messed me up. My row validation checks for required fields. The empty add line will never have any of the required fields, so it will always fail. At that point, I'm stuck on the add line and can't edit or delete any other row. I've gotten around it by skipping row validation on its first call for a new record, but I'm not sure this will entirely solve the problem. What property tells me this is an empty add row?

Hello Ruth Goldberg,
You could check the row type when handling RowValidating event. For this purpose use the Row property of the event arguments. When it is validating the new row this property will be of type GridViewNewRowInfo. I hope this helps. I will be able to be more precise in my suggestion if you send me your application.
RowValidating fires when setting the DataSource to synchronize the current row with the currency manager. You can skip this step by attaching to the event after setting the DataSource property.
Should you have other questions, please write back.
Best wishes,

I'm already checking the row type, but I do validating on new rows also. I want to know how I can tell the row is empty and never had any text typed into it. What property or properties will tell me that. My program is in vb.net, not C#, so I don't have to attach to events.

Hi Ruth Goldberg,
I understand; interesting scenario. You could use the Tag property of the row to save the information whether the row is edited or not. Another approach is to iterate all cells and check whether their value is different from DBNull. Please, could you send me your application. This way I will be able to give more precise suggestions. I am looking forward to your project.
