Use the InvalidateNode method to force the TreeList control to repaint the desired node. This is useful when you want a node to change its look & feel when it is not repainted automatically. For instance, a node’s indicator cell is not repainted when navigating through cells. Thus, you must force node repainting manually if you want to update the node as a result of such changes.

Remember that nodes include cells, preview section, node images, expand/collapse buttons and the node indicator cell.

Basically, you need to do the following to use the InvalidateNode method effectively.

The TreeList.InvalidateNodes method enables you to repaint all currently visible nodes.
