This seems to be a bug in our Demo examples. The application is loading Examples.VB.xap but after that you download another XAP file for each control examples. For some reason after downloading the correct Examples.VB.xap then it downloads the .CS version of the control XAPs.
We will investigate the issue and will be fixed for one of our next releases. For now if you want to change and try something in our examples you will need to create new project and copy the code of the example there and then modify it.
Please, excuse us for the inconvenience. We have added points to your account for the report. Don't hesitate to contact us if you have other questions.
