Hi Rohit,
If you have placed the subform in Design page:Try to use the below FormCalc in event: formready
Assuming that you have 5 rows in the table and want to validate each row……
If ($.parent.row1 == null ) and
($.parent.row2 == null and
($.parent.row3 == null and
($.parent.row4 == null and
($.parent.row5 == null ) then
$.presence = “hidden”
Else
$.presence = “visible”
If you have placed the subform in Master page:Try to use the above FormCalc in event: layoutready
Hope it works!
Naveen
