GridColumn.AllowGrouping Property

Gets or sets a value that specifies whether an end-user can group data by the current column. This is a dependency property.

Namespace: DevExpress.Xpf.Grid

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

NuGet Package: DevExpress.Wpf.Grid.Core

Declaration

C#

public DefaultBoolean AllowGrouping { get; set; }

VB.NET

Public Property AllowGrouping As DefaultBoolean

Property Value

Type	Description
DefaultBoolean	A DefaultBoolean enumeration value that specifies whether an end-user can group data by the current column.

Available values:

Name	Description	Return Value
True	The value is true.	0
False	The value is false.	1
Default	The value is specified by a global option or a higher-level object.	2

Remarks

End-users are allowed to group data if the view’s GridViewBase.AllowGrouping property is set to true. Individual columns provide the AllowGrouping property, allowing the default behavior specified by the view, to be overridden. Setting this property to ‘True’ or ‘False’ overrides the default behavior. This can be useful when it is required to prevent an end-user from grouping data by values of specific columns.

If the AllowGrouping property is set to ‘Default’, the ability to group data is controlled by the view’s GridViewBase.AllowGrouping property. In this instance, to obtain whether an end-user can group data by the current column, use the GridColumn.ActualAllowGrouping property.

Note

Data grouping requires data sorting to be performed. End-users can group data only if data sorting is allowed.
