It's possible to differentiate between which combobox-column was clicked by the columnindex. Small example:

Private Sub dataGridView1_EditingControlShowing(sender As Object, e As DataGridViewEditingControlShowingEventArgs) Handles dataGridView1.EditingControlShowing
    If TypeOf e.Control Is ComboBox Then
        If dataGridView1.CurrentCell.ColumnIndex = 1 Then
            Dim cb As ComboBox = TryCast(e.Control, ComboBox)

            'remove handler if it was added before
            RemoveHandler cb.SelectedIndexChanged, AddressOf ColumnCombo1SelectionChanged
            AddHandler cb.SelectedIndexChanged, AddressOf ColumnCombo1SelectionChanged
        ElseIf dataGridView1.CurrentCell.ColumnIndex = 2 Then
            Dim cb As ComboBox = TryCast(e.Control, ComboBox)

            'remove handler if it was added before
            RemoveHandler cb.SelectedIndexChanged, AddressOf ColumnCombo2SelectionChanged
            AddHandler cb.SelectedIndexChanged, AddressOf ColumnCombo2SelectionChanged
        End If
    End If
End Sub

Private Sub ColumnCombo1SelectionChanged(sender As Object, e As EventArgs)
    Dim sendingComboEdit = TryCast(sender, DataGridViewComboBoxEditingControl)
    Dim selectedValue As Object = sendingComboEdit.SelectedValue
End Sub

Private Sub ColumnCombo2SelectionChanged(sender As Object, e As EventArgs)
    Dim sendingComboEdit = TryCast(sender, DataGridViewComboBoxEditingControl)
    Dim selectedValue As Object = sendingComboEdit.SelectedValue
End Sub
