i have checkbox field in slickgrid uses yesnocheckboxcelleditor , wants user confirm change. have tried adding vildator:mymethod no success.

my guess have modify function 

this.applyvalue = function (item, state) {                 item[args.column.field] = state;             };

in editor. put whatever conditional logic need , apply value if needed.

this.applyvalue = function (item, state) {          var applyvalue = (...<your logic goes here>...);          if (!!applyvalue){                        item[args.column.field] = state;          } };
