I've got a datatable with two bindingsources bound to it.

I'm using the first bindingsource to bind my table to a datagridview. The second bindingsource is bound to a combobox in a second datagridview.

If I'm adding a new row using the bindingnavigator of the first datagridview, then I get the message "datatable internal index corrputed: '5'. When I don't use a second bindingsource I don't have the problem.

So it seems the problem is related to binding two bindingsources to the same datatable and adding new items to the datatable using one of the bindingsources.

Is there a way to overcome this? Or am I doing something wrong. I want the changes that I make in the datatable to be immediately reflected in the combobox that displays items of this datatable.
