詳細
SortPosition determines how the data is sorted within the list.
The control with a SortPosition of 1 will be the primary sort.
The sort heirarchy is dynamic. If a new control is added to the sort at position 1, all existing SortPositions will increment by 1.
Setting SortPosition to 0 will remove a control from the sort hierarchy.
