I have implemented ExpandAllHierarchyItems ( and collapse)
They take quite a few seconds to execute , which is not a problem I could put a busy spinner up.
Is there an event to say they have completed ?

The expanding of the hierarchy items happens between two Layout passes of the RadGridView. There is not a specific event. But it would be not appropriate to put a busy spinner up as the UI Freezes until the Layout is updated after the expanding.
May you specify what your scenario is? Is it possible for you to send us a sample project so that we might give you some suggestions on how to improve the performance?
All the best,
