Hi Everybody,
If i am providing "RETURN NO-APPLY" with in ANY-PRINTABLE trigger for the field then i am not able to enter any value to the same. Can anyone explain me briefly what exactly RETURN NO-APPLY does here?

Why is it happening so???

DEFINE VARIABLE field1 AS CHARACTER NO-UNDO.

DEFINE FRAME frame1
field1.

ON ANY-PRINTABLE OF field1 IN FRAME frame1
DO:
RETURN NO-APPLY.
END. /** ON ANY-PRINTABLE OF field1 **/

/** Start of Main **/
UPDATE field1 WITH FRAME frame1.
Click to expand...
Please do the needful. Thanks in advance.
 
Simply put, it returns you where you (read the Progress Client) came from when the event fired - it was probably sitting somewhere in a wait-for or something - without actually applying the event (in this case a character that was entered) to the object. There are many uses for return no-apply since it not only works in any-printable events but can basically be used in any user-interface event (for instance on leave of an object, return no-apply will make the leave not happen).

So in case of your example, a return no-apply in an any-printable event causes the character you typed not to show in field1.
 
I don't get you exactly. U have mentioned like "SOMETHING", can u be bit clear on the information provided???

I have basic knowledge on what RETURN NO-APPLY does. But i am not clear wat it does in this particular scenario. Y is that the value not getting displayed on the text field???
 
The value does not get displayed because the character that was typed in is not applied to the field (no-apply).
