也许这已经很晚了，但请尝试将其添加到您的代码中：

Private Sub dg1_CellValueChanged(sender As Object, e As DataGridViewCellEventArgs) Handles dg1.CellValueChanged
    Try
        dg1.CommitEdit(DataGridViewDataErrorContexts.Commit)
        If e.ColumnIndex = 9 Then 'columindex for your QUANTITY. 9 is just a sample
            dg1.CommitEdit(DataGridViewDataErrorContexts.Commit)
            dg1.CurrentRow.Cells("SubTotal").Value = (VAL(dgSalesOrderLine.CurrentRow.Cells("SalesOrderAmount").Value) * VAL(dgSalesOrderLine.CurrentRow.Cells("SalesOrderQuantity").Value))
        End If
    Catch ex As Exception
    End Try
End Sub


Private Sub dg1_CurrentCellDirtyStateChanged(sender As Object, e As EventArgs) Handles dg1.CurrentCellDirtyStateChanged
    dg1.CommitEdit(DataGridViewDataErrorContexts.Commit)
End Sub
