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.

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.
