Windows forms DataGridView binding save when last row is selected

Hello,

I'm having some problems when using DataGridView with a datasource and defaultvaluesneeded.

I have a grid bounded to a BindingList and when i try to Save, if the last row is selected, than i have an extra entry in the BindingList for that last row. It has only the values from defaultvaluesneeded. 

Is there a way to prevent that?

Thanks in advance,

Sergiu

Best Regards.
