รบกวนเรื่อง การใส่รูปใน Gridview แบบมีเงื่อนไข ASP.NET VB

Protected Sub GridView1_DataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound

        If e.Row.RowType = DataControlRowType.DataRow Then
            max_num = CInt(DataBinder.Eval(e.Row.DataItem, "volume"))
            If (max_num < min_num) Then
                'e.Row.BackColor = Color.Orange
                e.Row.ForeColor = Color.Orange

           End If
            If (max_num = min_num) Then
                'e.Row.BackColor = Color.Green
                e.Row.ForeColor = Color.Green
            End If
            If (max_num > min_num) Then
                'e.Row.BackColor = Color.Red
                e.Row.ForeColor = Color.Red
            End If
        End If
    End Sub
