Namespace: DevExpress.Xpf.Grid

Assembly: DevExpress.Xpf.Grid.v23.2.dll

NuGet Package: DevExpress.Wpf.Grid.Core

Declaration

C#

public void GroupBy(
    string fieldName,
    bool mergeWithPreviousGroup = false
)

VB.NET

Public Sub GroupBy(
    fieldName As String,
    mergeWithPreviousGroup As Boolean = False
)

Parameters

Name	Type	Description
fieldName	String	A String value that specifies the column’s field name.

Optional Parameters

Name	Type	Default	Description
mergeWithPreviousGroup	Boolean	False	A boolean value that specifies whether the current grouping should be merged with a previous grouping (according to group index).

Remarks

The GridControl supports data grouping by an unlimited number of columns. The GroupBy method groups data by the values of the specified column.

Data rows are always sorted against the grouping columns. If data is grouped against a column which isn’t sorted, the grid automatically applies sorting in ascending order to this column.
