Serializing/Deserializing RadTileView

[Grey]

Hi support,

I'm needing to store a RadTileView into IsolatedStorage to persist its state across application instances and need to serialize and deserialize the object. Serialization is working fine, but on the Deserialisation .Net is throwing an exception when trying to reflect the ItemsControl type. It's looking like its not resolving the conflicting ItemsControl type name from an empty XML namespace....

Please see the stack trace below for more information.

Note, the Dashboard property is a RadTileView with multiple RadTileViewItems (with RadFluidContentControls as their content.).

Thanks in advance!

Hi Grey,

Excuse me for the delayed response. Can you please send me a sample project that demonstrates the error so that I can investigate it?

Kind regards,

Hello,

I got the same problem with XMLSerializer and SharpSerializer, that always happens during serialization.
Partially the Persistence Framework and the LoadLayout/SaveLayout works, but a lot of information get lost by using them.

The DataContractSerializer and the ProtocollBuffers can't serialize them, its not possible to set the required attributes in closed source classes, so I'm a little lost with this problem.

I provide the Serialization errors, I've got below.

Best regards
Andreas

Hi Andreas,

 Could you please elaborate more on your exact scenario? Particularly:

• which Telerik control you are trying to serialize ?
• which of the control's properties you are not able to serialize ?
• what are the exact issues with the RadPersistenceFramework ?

Is it possible for you to send us an isolated sample replicating your issues in a new support thread ? This way we would be better able to investigate your scenario. Thank you in advance for your cooperation.
