A collection of SortProperty objects.
Namespace : DevExpress.Xpo
Assembly : DevExpress.Xpo.v25.2.dll
NuGet Package : DevExpress.Xpo
[ListBindable(BindableSupport.No)]
public sealed class SortingCollection :
IList,
ICollection,
IEnumerable,
IEnumerable<SortProperty>

Implements IList,

IEnumerable(Of SortProperty)
The following members return SortingCollection objects:
| Library | Related API Members |
|---|---|
| XPO (.NET ORM Library) | ObjectsQuery.Sorting |
| ObjectStubsQuery.Sorting | |
| XPBaseCollection.Sorting | |
| XPCursor.Sorting | |
| XPDataView.Sorting | |
| XPObjectSource.Sorting | |
| XPView.Sorting | |
| XAF: Cross-Platform .NET App UI & Web API | XPObjectSpace.CreateSortingCollection(IList<SortProperty>) |
The following members return SortingCollection objects:
The collection can be assigned to the XPCollection, XPView, XPDataView, or XPCursor object via an object’s Sorting property.
Note
Don’t make your code dependent on the order of records returned by these objects, unless you’ve explicitly sorted them. By default, if the XPCollection, XPView, XPDataView, or XPCursor is not sorted, records will be returned in an arbitrary order. This mimics the behavior of the SQL SELECT statement used in the same circumstances.
The following example demonstrates how to sort a collection (xpCollectionPerson) in ascending order against a ‘Name’ field.
using DevExpress.Xpo;
using DevExpress.Xpo.DB;
SortingCollection sortCollection = new SortingCollection();
sortCollection.Add(new SortProperty("Name", SortingDirection.Ascending));
xpCollectionPerson.Sorting = sortCollection;
Imports DevExpress.Xpo
Imports DevExpress.Xpo.DB
Dim sortCollection As SortingCollection = New SortingCollection()
sortCollection.Add(New SortProperty("Name", SortingDirection.Ascending))
XpCollectionPerson.Sorting = sortCollection
Object SortingCollection
