如何製作pdf文件有功能按鈕?在PDF中插入一個按鈕
本PDF
public partial class Pdf_Default : System.Web.UI.Page
{
protected override void Render(HtmlTextWriter writer)
{
MemoryStream mem = new MemoryStream();
StreamWriter twr = new StreamWriter(mem);
HtmlTextWriter myWriter = new HtmlTextWriter(twr);
base.Render(myWriter);
myWriter.Flush();
myWriter.Dispose();
StreamReader strmRdr = new StreamReader(mem);
strmRdr.BaseStream.Position = 0;
string pageContent = strmRdr.ReadToEnd();
strmRdr.Dispose();
mem.Dispose();
writer.Write(pageContent);
CreatePDFDocument(pageContent);
}
public void CreatePDFDocument(string strHtml)
{
string strFileName = HttpContext.Current.Server.MapPath("test.pdf");
// step 1: creation of a document-object
Document document = new Document();
// step 2:
// we create a writer that listens to the document
PdfWriter.GetInstance(document, new FileStream(strFileName, FileMode.Create));
StringReader se = new StringReader(strHtml);
HTMLWorker obj = new HTMLWorker(document);
document.Open();
obj.Parse(se);
document.Close();
ShowPdf(strFileName);
}
public void ShowPdf(string strFileName)
{
Response.ClearContent();
Response.ClearHeaders();
Response.AddHeader("Content-Disposition", "inline;filename=" + strFileName);
Response.ContentType = "application/pdf";
Response.WriteFile(strFileName);
Response.Flush();
Response.Clear();
}
}後面的代碼
當我試圖把一個返回按鈕,PDF文件僅顯示標籤測試。 我想製作一個可以轉到另一個頁面的按鈕(非PDF)。謝謝!
