Hi reema,

what is local:HierarchicalDataSource?

Are you sure it is defined and it exists?

Hi reema,

The blog post you are refering to happens to be a bit outdated and we will update it ASAP. I am sending you a working example which correctly demonstrates what's described in the article. Let me know if this solves your problem.

Best wishes,

Another example where information is would be more beneficial than a download.  This practice of "example only" is not the best choice for those seeking information.
