CheckEdit.IsThreeState Property

Gets or sets whether the check editor supports three states (checked, unchecked and indeterminate).

Namespace:DevExpress.Xpf.Editors
Assembly:DevExpress.Xpf.Core.v17.1.dll

Expanded Syntax

Property value

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

Expanded 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 (Checked, Unchecked or Indeterminate).
