The online example in question is designed to work as follows: when you select a user from the combo box the web form remembers what use has been selected but does not automatically load the grid settings for that use. In order to do so, you need to press the Load Settings button. If you need the grid settings to automatically load on post back from the user combo, just implement the following steps:
1. When the page initially loads, persist the grid settings into a session variable with a key name chosen by you, e.g. Session["DefaultUser"] = SavePersister.SaveSettings();
2. When you change the user from the drop-down, check if such a user key exists in the Session collection. If not, load the settings for the DefaultUsert.
Hope it helps.
All the best,
