A workaround is to add the settings in the markup, for example: <telerik:RadPersistenceManager runat="server" ID="RadPersistenceManager1"> <PersistenceSettings> <telerik:PersistenceSetting ControlID="RadTileList1" /> </PersistenceSettings> </telerik:RadPersistenceManager> <telerik:RadTileList runat="server" ID="RadTileList1"> </telerik:RadTileList>
