Remarks
An end-user can switch node states by clicking the check box. If the AllowIndeterminateCheckState property is disabled, a click on the check box changes the node’s state between checked and unchecked. If the AllowIndeterminateCheckState property’s value is true, successive clicks on the check box switch between three states: checked, unchecked and indeterminate.
Regardless of the AllowIndeterminateCheckState, you can apply the interderminate state to a node in code, using the TreeListNode.CheckState property.
