This might be a easy quest but I'm fairly new to programmming for dynamics crm.
We have a customer portal set up, and we want to be able to show a list of the campaigns that the current user has responded to. I thought it would be easy but it's proving to be more difficult then I realized. I tried using the activityparties
but that does work with RetrieveMultiple.
So what is the correct way of doing this?
