CheckEditSettings.IsThreeState Property

Gets or sets whether the check editor supports three check states. This is a dependency property.

Namespace: DevExpress.Xpf.Editors.Settings

Assembly: DevExpress.Xpf.Core.v24.2.dll

NuGet Package: DevExpress.Wpf.Core

#Declaration

public bool IsThreeState { get; set; }

#Property Value

Type Default Description
Boolean false

true if the check editor supports three check states; otherwise, false.

#Remarks

If the IsThreeState property is set to false, only two states - Unchecked and Checked are available.

If the IsThreeState property is true, a check editor can take one of three check states: Unchecked, Checked, and Indeterminate. In the indeterminate (also called “grayed”) state, the editor’s check box is displayed with a dimmed appearance to indicate that the option is unavailable. You can handle the CheckEdit.Indeterminate event to respond to setting the check editor to the Indeterminate state.
