The item interactions in MindFusion.Scheduling are not implemented as .NET drag-and-drop operations, therefore all members related to drag-and-drop (such as DragDrop, DragEnter, AllowDrag and AllowDrop) do not affect item interactions in any way. Instead you should use the properties and events of the Calendar control and the Item objects.

To disable item interactions, you can simply handle the ItemModifying event of the Calendar control and set the Confirm property of the associated event argument to false. You can also disable interaction on per-item basis through the AllowChangeStart, AllowChangeEnd and AllowMove properties of individual items. For example, setting AllowChangeStart and AllowChangeEnd on an item to false will prevent this particular item from being resized interactively.
