TreeListNode.CheckState Property

Gets or sets the node's check state.

Namespace:DevExpress.XtraTreeList.Nodes
Assembly:DevExpress.XtraTreeList.v19.2.dll

Expanded Syntax

Property value

Type: CheckState
A System.Windows.Forms.CheckState enumeration value that specifies the node's check state.
The default is CheckState.Unchecked.

Expanded Remarks

If the TreeListOptionsBehavior.AllowIndeterminateCheckState option is disabled, a node can have two states: checked and unchecked. In this mode, to get/set check states, use the Checked property.

If the TreeListOptionsBehavior.AllowIndeterminateCheckState option is enabled, three check states are supported: checked, unchecked and indeterminate. In this instance, use the CheckState property to get/set a node's state.

See Node Checking - Checkboxes and Radio Buttons to learn more.

Expanded Example

The following code shows how to retrieve checked nodes using the TreeList.GetAllCheckedNodes method, and modify their values.
