In this example you can see how to preserve the state of RadGrid using
a custom storage provider. For the purpose of this demo we have created a simple
CookieStorageProvider that uses GZip compression to reduce the
size of the settings before saving them in a cookie (with Base64 encoding).
Put simply, the custom provider has a SaveStateToStorage and LoadStateFromStorage
methods which are used by the PersistenceManager to load/save the state.
RadGrid settings persisted by the PersistenceManager include Sorting, Filtering,
Grouping, Edit/Insert Indexes, and Paging.
Please use the Save/Load/Reset buttons to test the functionality demonstrated by this example.
