BarBaseButtonItem.GroupIndex Property

Gets or sets the group index of the button item.

Namespace: DevExpress.XtraBars

Assembly: DevExpress.XtraBars.v19.2.dll

Declaration

C#

[DefaultValue(0)]
public virtual int GroupIndex { get; set; }

VB.NET

<DefaultValue(0)>
Public Overridable Property GroupIndex As Integer

Property Value

Type	Default	Description
Int32	0	The group index of the button item.

Remarks

When an item’s GroupIndex property is set to 0, it behaves independently of all the other bar items. If several items have the same non-zero GroupIndex, they are grouped together. When a user clicks one of these items, it remains selected until another item belonging to the same group is clicked.

The BarBaseButtonItem.AllowAllUp property determines if all the items in a group can be unselected simultaneously.

For BarButtonItem objects and their descendants the GroupIndex property is in effect only if the BarButtonItem.ButtonStyle property is set to BarButtonStyle.Check.
