Namespace: DevExpress.Xpf.Grid

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

NuGet Package: DevExpress.Wpf.Grid.Core

Declaration

C#

public void GroupByColumn(
    string fieldName,
    int index,
    ColumnSortOrder sortOrder = ColumnSortOrder.Ascending,
    MergeGroupPosition mergeGroupPosition = MergeGroupPosition.None,
    bool refreshMerge = true
)

VB.NET

Public Sub GroupByColumn(
    fieldName As String,
    index As Integer,
    sortOrder As ColumnSortOrder = ColumnSortOrder.Ascending,
    mergeGroupPosition As MergeGroupPosition = MergeGroupPosition.None,
    refreshMerge As Boolean = True
)

Parameters

Name	Type	Description
fieldName	String	A String value that specifies the column’s field name.
index	Int32	An integer value that specifies the column’s position among grouping columns.

Optional Parameters

Name	Type	Default	Description
sortOrder	ColumnSortOrder	Ascending	A ColumnSortOrder enumeration value that specifies the column’s sort order.
mergeGroupPosition	MergeGroupPosition	None	A MergeGroupPosition enumeration value that specifies the merging position.
refreshMerge	Boolean	True	A Boolean value that specifies whether the merged column should or not change the GridColumn.MergeWithPreviousGroup property to false.

Remarks

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.

Note

The refreshMerge parameter is in effect when the mergeGroupPosition parameter is set to MergeGroupPosition.Right.
