Write the code in Pai. Once press the Enter button pai will be trigger no, Get the input value from pro1 and Get or fetch from the data base or Required table. Now val1 field you are having then fill the Screen painter field of val1. then it display the value.
Hope you understood.


Thanku Sir,

for enter which function code we use and any event required for that like process on value-request...


I think no event you need, Just Write the code in Pai. After press enter Pai code will be trigger.


Runt above program, and give the input then press enter button then second field i getting automatically. Check it.


That's right sir actually I have used process_on_value_request event but your idea is good bcoz that is Simple way we can validate inputs.
