    1. COYou are missing the point. There is a Exception Framework implemented this framework that translates the exceptions to use friandly messages, this is why we throw the inner excpetion in here. Remeber we are making a wrapper for EF so this works under this context, the Wrapper takes care of the exceptions and throws. This would not be good in other contexts, but under this context this it correct. Be aware of the context, the throw here is just changing the mains message, the whole excpetion is there (no informationis lost), is just a matter of handlig the MESSAGE of the Excpetion.

    2. COTo be honest, is kind of hard to help you with such an specific issue, if you could replicate this in simpler code and then edit you questino with the Designer code of you sample we can replicate and then really inderstand the issue, that for me is still unclear. Im jus trying to help :)

    3. COThe question was about general use, so keep im mind that this is just one sample to help to explain. This is not the point of the question. The point of the try catch is to be able to show the inner exception that is raised instead of a more generic error. Also using Set<TEntity>().Add(entity) would work in this case, but there are some point where we cannot use the generic version (e.g when you have inheritance and have to use the .TypeOf<>)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
