Thank you very much for your help. I download the module and tried. What I did is create a new project and use Visual Studio to open the newly created website, add existing project (Telerik.Samples.Products) to the website. However, I am stucked at the following step:
"Expand the References folder in the Telerik.Samples.Products and fix reference problems if any (this can happen if your website is using a different version of Sitefinity than the one I used to create a sample) "
Could you please tell me how do I fix this issue? If I remove the reference, where can I find it to readd them?
