Assembly: DevExpress.Web.v21.2.dll

NuGet Package: DevExpress.Web

Declaration

C#

[DefaultValue(DefaultBoolean.Default)]
public DefaultBoolean AllowGroup { get; set; }

VB.NET

<DefaultValue(DefaultBoolean.Default)>
Public Property AllowGroup As DefaultBoolean

Property Value

Type	Default	Description
DefaultBoolean	Default	True to enable grouping. False to disable grouping. Default to control the column’s behavior at the control level (the ASPxGridViewBehaviorSettings.AllowGroup property).

Available values:

Name	Description
True	true. DefaultBoolean.True has a constant value of 0, while the standard true value corresponds to a value of 1. In Visual Basic, do not use implicit conversion of Boolean values to DefaultBoolean, and vice versa, as the conversion may produce incorrect results.
False	false. DefaultBoolean.False has a constant value of 1, while the standard false value corresponds to a value of 0. In Visual Basic, do not use implicit conversion of Boolean values to DefaultBoolean, and vice versa, as the conversion may produce incorrect results.
Default	The default behavior determined by the control’s logic.

GridViewDataColumn	.Settings .AllowGroup

Remarks

Specify the AllowGroup property to control grouping at the column level.

If the column’s AllowGroup property is set to Default, the control determines the column’s behavior at the control level based on the ASPxGridViewBehaviorSettings.AllowGroup property value.
