I'm attempting to use the PersistenceFramework with a GridView control for the first time using the example shown here:
http://www.telerik.com/help/wpf/persistence-framework-getting-started.html

I'm importing the namespaces:
Imports Telerik.Windows.Controls
Imports Telerik.Windows.PersistenceFramework
Imports Telerik.Windows.Persistence.Storage

I have the StorageID set in my GridView:
<telerik:RadGridView Name="gvComp" telerik:StyleManager.Theme="Office_Black"  AutoGenerateColumns="False" FrozenColumnCount="3" telerik:PersistenceManager.StorageId="gvComp_Layout" EditTriggers="CellClick,TextInput,CurrentCellClick" ShowColumnFooters="True" ShowGroupFooters="True" VerticalAlignment="Stretch">

I'm saving and loading grid when the app closes and loading the grid when it opens:

Dim isoProvider As New IsolatedStorageProvider()
isoProvider.SaveToStorage()
 
Dim isoProvider As New IsolatedStorageProvider()
isoProvider.LoadFromStorage()

When LoadFromStorage() runs I get the error:  "Token not valid" 
Can someone please give me some idea what I've done wrong?  This seems really simple in the example.

Using this method will save the grid settings between application uses correct? 

Thank you for the help.

I would like to add, the RadGrid in my application is large and complex.  If you can give me an idea what "Token is not valid" might be referring to, it will give me some direction for troubleshooting. 

Really, all I want to persist is column order and filters.  Can I specify what grid criteria to persist within the framework?

Thank you for your help.

Hi Ben,
I already answered the support thread and I'd like to paste my answer here so that other clients with similar problems may read it:
"Due to the complexity of the RadGridView we advice our clients to save it with a CustomPropertyProvider. We have an online demo that shows how to do this and I've also attached a sample application so could you please examine it and if you have more questions feel free to ask."
