Then you must elaborate more about your needs! How can I help you otherwise?

This is the easiest way to get around (I like LINQ very much).

When you say form name do you think of form's title or something else?

I am sorry, but your method HabilitaBotoes should have FormClosedEventHandler as type for second parameter (was writing answer on machine without VS).
And I really suggest you should use fcc.ShowDialog(this);(just comment out the two methods and event handler assignment and you are done).
By the way when adding event handler to event after typing fcc.FormClosed += hit the TAB key twice and it will create handler for you. Nece, isn't it.
And, yes if I have answered your question please mark it as answer. Thanks.

Maybe you should give us more information or some code...so that we can help you. Peace.

Just reference existing combobox or if you are dynamically creating one add it to Controls collection or what I know where you want it to be. Bind data and you are done.

Please elaborate more about your problem!

Thanks Richard! And yes fatima...68, Richard is right just read DataGridView.CellEndEdit Event. As I mentioned in my solution MSDN is the place.

That is the point of the infinite scroll that the user thinks that you are showing all the data immediately to him where in fact you load data in chunks and not all in one peace.
