Windows DataGridView BindingSource Index Beyond Exception

Scenario:

I basically have

  • System.Windows.Forms.DataGridView

  • Class inheriting from BindingSource and IBindingList

  • A class that has 2 standard lists as private properties

DataGridView dgv = new ...

MyBindingSource bindingSource = new ...

MyList List = New ...

The DataGridView.DataSource property is set to BindingSource, and BindingSource.DataSource is set to one of the private List.

bindingSource.DataSource = list.ListA;

dgv.DataSource = bindingSource;

I get a bunch of information coming from the database, and I convert the information into objects and add it to MyList one at a time and at the end should be displayed in the DataGridView.
