To have a refresh of master grid when you modified a row in the subgrid, using the inline option, you can use:
$grid["onAfterSave"] = 'function() { $("#list1").trigger("reloadGrid", [{current:true}]); }';
$g->set_options($grid);

but the same code doesn't work when you add a new record in the subgrid neither if you delete a record, forever in inline(add) option.
Is there a solution?
Thanks in advance
