ASP.Net รบกวนขอคำแนะนำ เรื่องการแสดงรูปภาพจาก Binary ใน GridView หน่อยครับ

Partial Class ViewImg
    Inherits System.Web.UI.Page

    Dim objConn As New SqlConnection
    Dim objCmd As SqlCommand
    Dim strConnString, strSQL As String

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        strConnString = "Server=localhost;Uid=sa;PASSWORD=;database=mydatabase;Max Pool Size=400;Connect Timeout=600;"
        objConn.ConnectionString = strConnString
        objConn.Open()

        '*** DataTable ***'
        Dim dtAdapter As SqlDataAdapter
        Dim dt As New DataTable
        strSQL = "SELECT * FROM files WHERE FilesID = @sFilesID "
        dtAdapter = New SqlDataAdapter(strSQL, objConn)
        objCmd = dtAdapter.SelectCommand
        objCmd.Parameters.Add("@sFilesID", SqlDbType.Int).Value = Request.QueryString("FilesID")
        dtAdapter.Fill(dt)

        If dt.Rows.Count > 0 Then
            Response.ContentType = dt.Rows(0)("FilesType").ToString()
            Response.BinaryWrite(dt.Rows(0)("FilesName"))
        End If

        dt = Nothing
    End Sub

    Protected Sub Page_Unload(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Unload
        objConn.Close()
        objConn = Nothing
    End Sub

End Class
