Question

Is there any example available showing the use of a pure AJAX controlled  Gantt, i.e. not just the wrapped one?

Answer

In the download we only have Ajax samples wrapping the windows forms component(currently). The main reason for this is that when wrapping a windows forms Gantt you get access to the design time properties and that is practical. If you do not want the form in there you can always copy the designer-auto-generated-code to the webform or a class file.
