As previously stated  set your form s AcceptButton property to one of its buttons AND set the DialogResult property for that button to DialogResult OK  in order for the caller to know if the dialog was accepted or dismissed

Set the KeyPreview attribute on your form to True  then use the KeyPress event at your form level to detect the Enter key  On detection call whatever code you would have for the  submit  button

You can designate a button as the  AcceptButton  in the Form s properties and that will catch any  Enter  keypresses on the form and route them to that control   See How to  Designate a Windows Forms Button as the Accept Button Using the Designer and note the few exceptions it outlines  multi-line text-boxes  etc

If you set your Form s AcceptButton property to one of the Buttons on the Form  you ll get that behaviour by default   Otherwise  set the KeyPreview property to true on the Form and handle its KeyDown event  You can check for the Enter key and take the necessary action
