show/hide jqgrid delete button

I want to show/hide jqgrid delete button on the basis of specific data in jqGrid.

 $('#jqgFlagger').jqGrid('navGrid', '#jqgpFlagger',
            { add: false, del: false, edit: false, search: false },
            { width: 'auto', url: '/DtlmTransaction/UpdateRole' },
            { width: 'auto', url: '/DtlmTransaction/InsertRole' },
            { width: 'auto', url: '/DtlmTransaction/DeleteMultiple' });

Above is the code that shows that I'm not using jqgrid own delete option but the custom delete option from the action which is as under;

 colModel: [
                    { name: 'FlaggerName', resizable: false, index: 'FlaggerName', align: 'left', width: 312, editable: false },
                    { name: 'DataFileReceived', formatter: DataFileReceivedFormatter, resizable: false, index: 'DataFileReceived', width: 130, align: 'left', search: false, edittype: 'text' },
                    { name: 'ProcessStartDate', formatter: ProcessStartDateFormatter, resizable: false, index: 'ProcessStartDate', width: 130, align: 'left', align: 'left', search: false, edittype: 'text' },
                    { name: 'ProcessCompleteDate', formatter: ProcessCompleteDateFormatter, resizable: false, index: 'ProcessCompleteDate', width: 150, align: 'left', search: false, edittype: 'text' },
                    { name: 'Total', resizable: false, index: 'Total', width: 53, align: 'center', search: false },
                    { name: 'Identical', resizable: false, index: 'Identical', width: 53, align: 'center', search: false },
                    { name: 'Differences', resizable: false, index: 'Differences', width: 51, align: 'center', search: false },
                    { name: 'StateAbri', resizable: false, index: 'StateId', width: 48, align: 'left' },
                    { name: 'CountyName', resizable: false, index: 'CountyName', width: 86, align: 'left' },
                    { name: 'Name', resizable: false, index: 'ServiceName', align: 'left', width: 127 },
                    { name: 'StatusName', formatter: statusFormatter, resizable: false, index: 'StatusId', align: 'center', width: 70, search: false },
                    { name: 'StatusColor', hidden: true, resizable: false, index: 'StatusColor', align: 'left', width: 70, search: false },
                    { name: 'bitDefault', formatter: bitDefaultFormatter, resizable: false, index: 'bitDefault', align: 'left', width: 40, search: false, editoptions:开发者_如何学Python { value: '1:0' }, editable: false, edittype: 'checkbox' },
                    { name: 'Names', resizable: false, index: 'Names', align: 'left', width: 100,
                        search: false, sortable: false, formatter: editFmatter
                    },
                    { name: 'act', index: 'act', width: 50, align: 'center', sortable: false, formatter: 'actions',
                        formatoptions: {
                            keys: true,
                            editformbutton: false,
                            delbutton: true,
                            editbutton: false,
                            delOptions: { url: '/DtlmTransaction/DeleteMultiple' }
                        }
                    }],

Here you can see that in action i've enable delButton:true. Now i want to show/hide delete button on the jqgrid row's field data condtion. For example if i get the row's field value (success,complete, etc) then i want to hide this button. How can i do it? Please suggest.

Look at the demo from the answer. One more option is to disable navigator buttons based on the selected row like it shows in the demo from another old answer.
