A collection of sort conditions.

Namespace: DevExpress.Xpf.PivotGrid

Assembly: DevExpress.Xpf.PivotGrid.v19.1.dll

Declaration

C#

public class SortByConditionCollection :
    PivotChildCollection<SortByCondition>

VB.NET

Public Class SortByConditionCollection
    Inherits PivotChildCollection(Of SortByCondition)

Related API Members

The following members return SortByConditionCollection objects:

• PivotGridField.SortByConditions

Remarks

The SortByConditionCollection collection is used to identify the column/row by whose values the current field values will be sorted. This collection is stored in the field’s PivotGridField.SortByConditions property.

A collection of sort conditions contains SortByCondition objects (sort conditions). Each of the conditions corresponds to a field value, so that the whole collection identifies the required column/row. The ‘February 2, 2002’ column in the image below is identified by three sort conditions.

Example

The following example demonstrates how to sort data by a particular column.

In this example, values of the Product Name field are sorted by September 1994 column summary values. To do this, two sort conditions represented by SortByCondition instances are created. One of them identifies the ‘1994’ field value, while another identifies the ‘September’ value. These sort conditions are added to the Product Name field’s PivotGridField.SortByConditions collection to specify the column by which Product Name values should be sorted. A data field that identifies the column is specified via the PivotGridField.SortByField property.
