SortingCollection.Add(SortProperty) Method

Adds the specified SortProperty object to the collection.

Namespace: DevExpress.Xpo

Assembly: DevExpress.Xpo.v24.2.dll

Declaration

C#

public void Add(
    SortProperty sortProperty
)

VB.NET

Public Sub Add(
    sortProperty As SortProperty
)

Parameters

Name	Type	Description
sortProperty	SortProperty	A SortProperty object to add to the collection.

Remarks

Adding an element to the collection doesn’t automatically apply sorting by the corresponding property (column). To re-sort data, create a new SortingCollection object, populate it with the customized SortProperty objects and reassign it to the XPBaseCollection.Sorting property.

Example

The following example demonstrates how to sort a collection (xpCollectionPerson) in ascending order against a ‘Name’ field.

C#

using DevExpress.Xpo;
using DevExpress.Xpo.DB;

SortingCollection sortCollection = new SortingCollection();
sortCollection.Add(new SortProperty("Name", SortingDirection.Ascending));
xpCollectionPerson.Sorting = sortCollection;

VB.NET

Imports DevExpress.Xpo
Imports DevExpress.Xpo.DB

Dim sortCollection As SortingCollection = New SortingCollection()
sortCollection.Add(New SortProperty("Name", SortingDirection.Ascending))
XpCollectionPerson.Sorting = sortCollection
