Pov for table control

Hi all,

Iam using F4 help in table control. when the user selects the data 2 more fields in the table control should be updated. i am using dynp update function.

But i want to find out current line of the table control

which is the one of the input parameter to the dynp update function,when the user presses the f4 help..?

Tablecontrol-current-line is not working..

With Regards
