It may be possible that you know it but here I am going to share one simple tip to remove unwanted space occupied by required field validator control.
Just consider below login screen. On this field we have kept require field validator control.
Once you have changed the property to display dynamic the unwanted space automatically removed and it will consume only when validation failed.
The new screen will look like as below
So use display “Dynamic” property in required field validator.
Thanks & Best Regards,
