Hello, Sun,

Please have a look at the following help article which demonstrates how to notify the RadTreeView control for any changes and keep the state:

Indeed, it is also a suitable approach. The following tutorial demonstrates how to notify the control that your data source has changed by calling the ResetBindings method.
