editoptions:{dataInit : function (elem){$(elem).val("0");}}

and it works for only new but i want to reset value of cell to "0" even when i use form edit.

i also try

editoptions:{defaultValue:"0"}

and

editoptions:{value:"0"}

but all is working when use form edit for new row and when try to edit it show first time the default "0" value but when i cancel and again edit form then cell value is set in the text input field

Answer 1

beforeShowForm: function($form) {
setTimeout(function() {
    $form.find('input#credit.FormElement').val(0);
    },50);
}

works for me as when load the form i reset the value of Credit;

Answer 2

I think you need to set the value of the cell, when selecting the row, if it an inline edit.

onSelectRow: function (id) {
                if (id) {
                    selectedRowId = id; // save current row ID 
                    var myCellData = grid.jqGrid('getCell', selectedRowId , 'MyColName');
                }
            },

where id the row id, then you can find the cell value

Hope this helps you. Enjoy jqGrid.
