Hello
I have some controls (textboxs,picbox,checkbox) bind to a BindingSource. And this BindingSource.DataSource to a DataTable.

I need to know if some field has been modified in order to ask for save changes.

The problem is that when I use BindingSource.EndEdit(), the DataTable.GetChanges() always return TRUE even if none of the controls has been modified.

Any idea of what I'm doing wrong?

Thanks

What I have tried:

I have tried to use BindingSource.EndEdit() but it always makes DataTable.GetChanges() to get a row change.
