I am using a binding navigator in visual basic 2012 to access records in an Access database table.  Everything works as expected until I click the save button on the binding navigator.  The binding navigator has the following sub routine:

Private Sub TblDMPartBaseBindingNavigatorSaveItem_Click(sender As Object, e As EventArgs) Handles TblDMPartBaseBindingNavigatorSaveItem.Click
    End Sub

I use binding navigators in another project using the same dataset as this one with no problems.  Can anyone help me with this?
