- prop
- PropertyDescriptor
A PropertyDescriptor that specifies the property to sort on.
- direction
- ListSortDirection
One of the ListSortDirection values.
Exceptions
Method is not overridden in a derived class.
Remarks
The BindingList<T> class does not provide a base implementation of sorting, so ApplySortCore always throws a NotSupportedException by default. To enable sorting, derive from BindingList<T> and perform the following tasks:
Override ApplySortCore and implement sorting, raising the ListChanged event when sorting is complete.
Override RemoveSortCore and implement sort removal.
Override SupportsSortingCore and set SupportsSortingCore to
true.
In addition, you may want to implement the supplemental SortDirectionCore and SortPropertyCore sorting properties.
