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

NuGet Package: DevExpress.Wpf.Core

Declaration

C#

public bool IsThreeState { get; set; }

VB.NET

Public Property IsThreeState As Boolean

Property Value

Type	Default	Description
Boolean	false	true if the editor supports three states; false if the editor supports two states (checked and unchecked).

Remarks

A check editor supports three states (checked, unchecked, and indeterminate) if its IsThreeState property is set to true. Otherwise, if this property is set to false, only checked and unchecked states are supported.

Use the BaseEdit.EditValue property to specify the editor’s state. To set the editor to the indeterminate state (if supported), set the BaseEdit.EditValue property to null.

After the BaseEdit.EditValue property’s value has been changed, the check editor fires the corresponding event (CheckEdit.Checked, CheckEdit.Unchecked, or CheckEdit.Indeterminate).

Use the CheckEdit.ReverseCheckOrder property to set the order of the check editor states.
