如何将包含Gridview控件和图像的面板导出到PDF

Question

我无法将包含Gridview和图像的面板导出为PDF。有什么建议吗？

这是我导出Gridview的代码，它成功完成了。但是我需要将Gridview和我的图像导出到Gridview上方，两者都包含在面板中。

 Using sw As New StringWriter()
                Using hw As New HtmlTextWriter(sw)
                    'To Export all pages
                    GridView1.AllowPaging = False
                    Me.LoadDataGrid()
                    GridView1.RenderControl(hw)
                    Dim sr As New StringReader(sw.ToString())
                    Dim pdfDoc As New Document(PageSize.A2, 10.0F, 10.0F, 10.0F, 0.0F)
                    Dim htmlparser As New HTMLWorker(pdfDoc)
                    PdfWriter.GetInstance(pdfDoc, Response.OutputStream)
                    pdfDoc.Open()
                    htmlparser.Parse(sr)
                    pdfDoc.Close()
                    Response.ContentType = "application/pdf"
                    Response.AddHeader("content-disposition", "attachment;filename=GridViewExport.pdf")
                    Response.Cache.SetCacheability(HttpCacheability.NoCache)
                    Response.Write(pdfDoc)
                    Response.[End]()
                End Using
            End Using
