TreeListView.ImmediateUpdateCheckBoxState Property

Gets or sets whether the focused row’s check box value is posted immediately.

Namespace: DevExpress.Xpf.Grid

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

NuGet Package: DevExpress.Wpf.Grid.Core

#Declaration

[Browsable(false)]
public bool ImmediateUpdateCheckBoxState { get; set; }

#Property Value

Type Default Description
Boolean false

If true, the focused row’s check box value is posted immediately. If false, the focused row’s check box value is posted after changing focus.

#Remarks

The focused row’s check box value is not posted until you focus another row. To make the TableView post check box values immediately, set the ImmediateUpdateCheckBoxState property to true.

#Checking Nodes in Code

Use the following methods to check/uncheck nodes in code:

Method Description
TreeListView.CheckAllNodes Checks all nodes.
TreeListView.UncheckAllNodes Unchecks all nodes.
TreeListNode.IsChecked Checks/unchecks the node.

When a node’s check state is changed, the TreeList View raises the TreeListView.NodeCheckStateChanged event. Use the TreeListNode.IsChecked property to identify whether a node is checked.
