Hi Derek,
There is no built in logic for sorting the TasksSource of the RadGanttView.
It is of type IEnumerable, thus whatever IEnumerable you choose to use will determine how the tasks are sorted. Could you provide more information of your scenario and what you wish to achieve in order for us to get a better understanding?

I'm trying to get the drag and drop reorder. So when they move an item up and down, I can get the position number.

Hello Derek,
The implementation of GanttTasks does not provide an order number out of the box. However, you can create a custom GanttTask and include additional properties that suit the needs of your application, in this case a property for the GanttTask order. You can find more information on how to create a custom GanttTask in this help article: http://docs.telerik.com/devtools/wpf/controls/radganttview/features/items/custom-gantttask
Then you can also create a custom GanttDragDropBehavior and override its Drop method, where you can extract the dragged GanttTask, its destination GanttTask and the drop position from the state method parameter and adjust the order properties accordingly. You can find more information on how to create a custom GanttDragDropBehavior in our Custom Drag and Drop behaviors help article.
Hope this helps.
