OK, I'm at a standstill. One of the controls on the form is UserControl i, which contains some bindings in it.
This worked fine. Now I have added the inhertience property of IEnumerable to my control so that it can return specific objects inside it for another function that I was trying to add. Now, if I 'Step-Into' calls .Show, I achieve the IEnumrable implementation made in a specific case.
Although at this time, he returned an empty collection, since I did not have items to return. Apparently, for some reason, it raised an ArgumentException, which I got with a DataBinding. The moment I remove IEnumrable inheritance from my control, everything returns to normal.
I absolutely do not know why this happened.
