Dear Developers,
I have a DB column having values 1 and 0 and i have displayed it in IG column as check box, now I need a check box in column header to select all / un-select all as indicated in screenshot below. Also i want to save these changes in DB when page submitted. any help will be highly appreciated,
P.S. This form has 1 Master IG and 2 child IG's. when we add row in master IG, child rows are automatically added from back end.
