求教，雖然上面已經收貨，但想再做好尐，依家想做埋HEADER同FOOTER，但出現問題

基本上是跟這個網做
http://www.cc.ntu.edu.tw/chinese/epa...01220_1509.htm
這部份是沒有問題

接著跟這裡做Header同Footer
http://www.cc.ntu.edu.tw/chinese/epa...0320_1610.html

但做不到，其中不明白這句是甚麼意思
>>"所以我們先建立Page Event class"
其實是要怎樣建立?

我的情況是在已經開了個叫pdf的project，然後在defalut.aspx.cs中輸入
http://www.cc.ntu.edu.tw/chinese/epa...01220_1509.htm
的code

跟著是要在defalut.apxs.cs中加入
http://www.cc.ntu.edu.tw/chinese/epa...0320_1610.html
的code

例如這樣
public partial class _Default : System.Web.UI.Page
{

}
public class TwoColumnHeaderFooter : PdfPageEventHelper
{
}

還是要在同一個Project中開新增一個class File，然後將所有code打落去呢??

兩種方法也做過，但都係冇嘢出……

另外也參考過
http://www.mazsoft.com/blog/post/200...F-library.aspx

也試了將所有CODE放在一起或在同一個PROJECT裡分成不同的CLASS FILE

不過在分成不同的CLASS FILE的情況下
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
SendOutPDF(new CustomReports().CreatePDF("Title: Sample 1"));
}

出現紅色說找不到這個CLASS

而將所有CODE放在一起時又說已有項目宣告了

(好在唔係寫Code搵食)

我睇應該係個 PdfWriter 未加番個 PdfPageEventHelper 落去?
根據你的 code, 在 Page_Load 的 PdfWriter PdfWriter = PdfWriter.GetInstance(doc1, Memory); 後加上:
TwoColumnHeaderFooter PageEventHandler = new TwoColumnHeaderFooter();
PDFWriter.PageEvent = PageEventHandler;
試試?
