The problem remains, I still have to click twice before I go to Edit mode and Editing doesn't work.

I'm throwing an exception in the Item Inserting Event which I excpect to catch in the Item Inserted event using the Form View Inserted Event Args, however, the event does not flow from Item Inserting -Yes, for example, I validate and findout the length of the input exceeds the permisable value, then I throw a new Validation Exception(), ofcourse, I can simply handle it using condition checking but the actual problem is when I have an SQL Exception.
