Remarks

If the AllowRecursiveNodeChecking property is enabled:

child nodes are automatically checked/unchecked when a parent node is checked/unchecked
a parent node is checked/unchecked, when you check/uncheck all its child nodes.

The node checking feature can be enabled with the TreeListOptionsView.CheckBoxStyle, TreeListOptionsView.RootCheckBoxStyle and TreeListNode.ChildrenCheckBoxStyle properties. See Node Checking - Checkboxes and Radio Buttons to learn more.

Note

If you enable the AllowRecursiveNodeChecking option and utilize the TreeList.CheckBoxFieldName property, the data source field should support null values.
