IEnumerable CoerceDraggedItems(SchedulingDragDropState state)DragDropState that provides context for the current operation.
Returns:The filtered dragged items.
This method is called immediately before the drag operation starts. Only the Items property of the DragDropState is valid.
When overridden in a derived class cleans up a cancelled drag operation. This method is called only in the context of the drag source control.
void DragDropCanceled(SchedulingDragDropState state)DragDropState that provides context for the current operation.
This method is called only when the drag operation is cancelled by the user. If this method is called, the source's DragDropCompleted and target's Drop methods are not called.

void DragDropCompleted(SchedulingDragDropState state, DragDropEffects dragDropEffects)DragDropState that provides context for the current operation.
dragDropEffectsDragDropEffectsDragDropEffects with which the drag operation have finished.
