Can not specify task type

Hello people,

this is my configuraiton of lightbox. When I run application I can not see “type” field property in the lightbox form - description and time I see, but type can not be seen. Please, what can be the problem?

gantt.config.lightbox.sections = [ { name: "description", height: 70, map_to: "text", type: "textarea", focus: true }, { name: "type", type: "typeselect", map_to: "type" }, { name: "time", height: 72, type: "duration", map_to: "auto" } ];

public class Task // model class { public int Id { get; set; } [MaxLength(255)] public string Text { get; set; } public DateTime StartDate { get; set; } public int Duration { get; set; } public decimal Progress { get; set; } public int SortOrder { get; set; } public string Type { get; set; } public int? ParentId { get; set; } }

Please note, all the other properties mapping are working just as expected…


Probably you use a free version of the component, does not support different types of tasks, you can request full functional evaluation version at

Thank you for answering…

When I run this example code than I do not have problems with type attribute.

OK. Thanks for answering…

Seems realy that it is only available in PRO.
