Property SortDescriptions
SortDescriptions
Collection of Sort criteria to sort items in this view over the inner IBindingList.
public override SortDescriptionCollection SortDescriptions { get; }Property Value
Remarks
If the underlying SourceCollection only implements IBindingList, then only one sort criteria in form of a SortDescription can be added, specifying a property and direction to sort by. Adding more than one SortDescription will cause a InvalidOperationException. One such class is Generic BindingList
Classes like ADO's DataView (the view around a DataTable) do implement IBindingListView which can support sorting by more than one property and also filtering CustomFilter
Some IBindingList implementations do not support sorting; for those this property will return an empty and immutable / read-only SortDescription collection. Attempting to modify such a collection will cause NotSupportedException. Use CanSort property on this CollectionView to test if sorting is supported before modifying the returned collection.
