In the development of business websites, we have encountered some hurdles in the use of Silverlight, in particular using the drag and drop functionality that was not easily solved by a quick search of the internet. There are many examples of using Silverlight drag and drop with file system utilities, but how does it work if you want to have drag and drop in your business application where the objects come from your database instead of a file system? All the examples we found ignore the need for a business application to know exactly what moved and from where and the need to update the database with the information that changed.
This article presents the solution we came up with to solve the problem of knowing which object was moved and details about that object. Due to the extensive functionality of Silverlight, there are probably other ways to solve this problem.
