why does the program not stop?
Apr 17 2021 11:10 AM
Hi
When i leave the field 'begdat' (of a gridview in editing mode) empty or with anything except date , i get the error 'Not a date 1' and i'm compelled to fill a valid date. The error "Not a date 2." at line 16 is never shown.
Now, if i remove lines 13 to 17 and i leave the field empty or with anything except date, line 18 gives this error "String was not recognized as a valid DateTime". This is what i don't understand. Normally, the program would be stopped at line 4. How come that line 4 now is ignored and that the program goes further?
Thanks.
