TreeViewControl.AllowIndeterminateCheckState Property

Gets or sets whether a 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.v20.2.dll

Declaration

public bool AllowIndeterminateCheckState { get; set; }
Public Property AllowIndeterminateCheckState As Boolean

Property Value

Type Default Description
Boolean

false

true, to allow users to select the indeterminate state of a check box; otherwise, false.

Remarks

Set the TreeViewControl.ShowCheckboxes property to true to display check boxes.

Set the AllowIndeterminateCheckState property to true to allow users to set the node's check boxes to three states (checked, unchecked, and indeterminate):

The AllowIndeterminateCheckState property allows users to select the indeterminate state of a check box. You can set this state in a data source or specify the TreeListNode.IsChecked property regardless of the AllowIndeterminateCheckState property's value. If you set the check state in a data source, use the TreeViewControl.CheckBoxFieldName property to apply this state to the TreeViewControl's check boxes.
