To elaborate on @tangerine's answer, in this scenario the "set formatter" is applied in the MVC Controller Action and not in the View. .Field(new Field("FridayPlanning.CourseOwnershipCalculatesOwnMath").SetFormatter(Format.IfEmpty(null)))

thank you very much Allan for your quick response, can you please tell me how can i make sure that row-reorder is applied on datatable, in my case i am initializing datatable with row re order, but when its rendered it has sorting-disabled class applied on that . below is code which i am using for initialization of databtable $(table).dataTable({ "pageLength": -1, "language": { "lengthMenu": " _MENU_ records" }, "columnDefs": [{ // set default column settings 'orderable': false, 'targets': [0,1,2,3,4,5,6] }, { "searchable": false, "targets": [0,1,2,3,4,5,6] }, { "targets": [6,3], "visible": false }], "order": [ [3, "asc"] ], // set first column as a default sort by asc rowReorder: {dataSrc:3}, info: false, paging: false, searching: false, retrieve: true, });

I'm sorry, but DataTables doesn't have a tree view mode at the moment. The closest is RowGroup, but I'm not sure that would meet your needs in this case? Allan

Here is a quick example: http://live.datatables.net/banigoba/1/edit I'm not sure how your code is structured nor how you know which column contains the icon. So this example assumes column 0 is the column to render and it just renders a link. Assigns to a variable that can then be used in the Datatables init function. Kevin

@allan Thanks.

Thanks Allan. Yes, Kevin's answered seemed to be for a different topic. Apologies for not pointing that out. Gabriel

Sounds like a sensible idea to me - I'll add in information about it. Thanks, Allan

The update method of the update field type is the way to do this. For example you might: $.getJSON( url, function ( json ) { editor.field( 'myField' ).update( json ); } ); Allan

Can you link to a page showing the issue, per the forum rules, please. DataTables should make no difference to the right click behaviour. Allan

Perhaps one option would be to use the UUID as the primary key? Having said that, if someone could do something bad by guessing an id, they could also do something bad by guessing a uuid. It might take them longer to guess it, but it isn't really security in my mind. Allan
