I have fixed the above question using a TypedList, but now my problem is this:
I am using windows forms, I have a grid and when you double click a row I open an edit Form for it.
I am using a currencyManager (datanavigator) so I was passing a collection to the EditForm and you could navigate trought the fetched collection and edit data.
Now that I have used the TypedList I am having troubles to send all the collection to the EditForm and allow user to navigate and edit results. What I am doing now is to send only the ID of the element that I need to edit.
How can you get an entitycollection from a TypedList??
Supose you have the CityId, CityName, StateID entitycollection and now I changed to a CityId,CityName, StateId,StateName typedList and need to create an EntityCollection of CityId,CityName and StateId so I can send it as I was doing before the TypedList
