TreeListView.AllowIndeterminateCheckState Property

Gets or sets whether an end-user can set the node’s check boxes to three states (checked, unchecked and indeterminate). This is a dependency property.

Namespace: DevExpress.Xpf.Grid

Assembly: DevExpress.Xpf.Grid.v18.2.dll

Declaration

C#

public bool AllowIndeterminateCheckState { get; set; }

VB.NET

Public Property AllowIndeterminateCheckState As Boolean

Property Value

Type	Description
Boolean	true to allow selecting the indeterminate state of a check box; otherwise, false.

Remarks

Indeterminate check state represents the null value.

The AllowIndeterminateCheckState property affects only the ability of an end-user to directly select the indeterminate state of check box. This state can be set by a data source or via recursive checking regardless of the AllowIndeterminateCheckState property’s value.
