ขอคำปรึกษาเรื่อง การใส่สีใน Datagrid รบกวนด้วยน่ะคับ

DataGridView.Rows(1).DefaultCellStyle.BackColor = Color.Azure

With DataGrid_H
            For i As Integer = 0 To .Rows.Count - 1
                If CInt((DataGrid_H.Rows(0).Cells(2).Value) <= (DataGrid_H.Rows(0).Cells(3).Value)) Then
                    .RowsDefaultCellStyle.BackColor = Color.Red


                End If
            Next
        End With

        For i As Integer = 0 To DataGrid_H.RowCount - 1
            If CDate(DataGrid_H.Rows(i).Cells(3).Value).Date >= Now.Date Then
                DataGrid_H.Rows(i).DefaultCellStyle.BackColor = Color.Red
            End If
        Next

    Private Sub dg_CellFormatting(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles dgSub.CellFormatting
        If e.ColumnIndex = 4 AndAlso sender.Rows(e.RowIndex).Cells("Balance").Value < 0 Then
            e.CellStyle.ForeColor = Color.Red
            e.CellStyle.BackColor = Color.LightCyan
        End If
        If e.ColumnIndex = 0 AndAlso sender.Rows(e.RowIndex).Cells("refDoc").Value = "ยกมา" Then
            e.CellStyle.ForeColor = Color.DarkGreen
        End If
    End Sub
