    Sometimes it may be useful to persist the expanded groups when exporting RadGrid data. The attached example illustrates how to implement this functionality with few lines of code. This project relies on the ViewState to hold the information about the expanded groups.
    The PersistExpandedGroups method will be invoked before export and the RestoreExpandedGroups will be called on DataBound event.
