WEBDEV entry focus (no replies)

Hi,

Under WEBDEV, I have an ENTRY field and a BUTTON ( Server side to check and update database ).
User will enter some information and hit ENTER key ( which will triggered the code in the BUTTON).

How to have the focus goes back to the ENTRY field after the logic checks in the BUTTON ? as the RETURNTOCAPTURE function only work in BUTTON's Browser side.

Regards,
