iTextSharp類在c中輸出pdf gridview＃

有了這個c＃代碼，我需要導出爲PDF格式的GridView。iTextSharp類在c中輸出pdf gridview＃

我使用iTextSharp類。

我的問題是我已經設置了超鏈接標記的最後一列gridview。

在導出pdf中超鏈接的圖像它沒有對齊在相應的單元格內，因爲移動到其他單元格的所有值。

請檢查附件圖像。

有人知道我怎麼能解決這個問題？

你能提出其他方法嗎？

預先感謝您。

請檢查下面的代碼。

for (int rowIndex = 0; rowIndex < gvProducts.Rows.Count; rowIndex++) 
     { 
     for (int j = 0; j < gvProducts.Columns.Count; j++) 
      { 
       if (j == 10) 
       { 
        cellText = (gvProducts.Rows[rowIndex].Cells[10].FindControl("img") as HyperLink).NavigateUrl; 
        string imagePath = Server.MapPath((gvProducts.Rows[rowIndex].Cells[10].FindControl("img") as HyperLink).ImageUrl); 
        iTextSharp.text.Image image = iTextSharp.text.Image.GetInstance(imagePath); 
        Chunk cImage = new Chunk(image, 0, 0, false); 
        Anchor anchor = new Anchor(cImage); 
        anchor.Reference = cellText.ToString(); 
        table.AddCell(anchor); 
       } 
       else 
       { 
        cellText = Server.HtmlDecode(gvProducts.Rows[rowIndex].Cells[j].Text); 
       } 

       cell = new PdfPCell(new Phrase(cellText, FontFactory.GetFont("PrepareForExport", 8)));     
       cell.HorizontalAlignment = Element.ALIGN_CENTER; 
       cell.VerticalAlignment = Element.ALIGN_MIDDLE; 
       cell.FixedHeight = 25f; 
       table.AddCell(cell); 
      } 
     }
