打印多個頁面不起作用

Question

從Question

這是回答真的很快到來，我已經在升級問題絆倒了。

我已經改變了我的程序來從數據庫中填充一些DataSet。

我打電話Print()上printDocument，一切正常，它只是不希望我的註冊e.HasMorePages = true;

這裏是代碼：

public static void printDokument() 
    { 
     if (result == DialogResult.OK) 
     { 

      DbDataPostavke = checkDB("SELECT * FROM " + tipDokumenta + "_postavke WHERE ID_" + tipDokumenta + " = " + stDokumenta); 

      list = DbDataPostavke.Tables[0].AsEnumerable().ToList();        
      printDocument.Print(); 
     }  
    } 

    static void printDocument_PrintPage(object sender, PrintPageEventArgs e) 
    { 
     graphic = e.Graphics; 

     e.PageSettings.PaperSize = ps; 

     stranSirina = e.PageSettings.PrintableArea.Width; 
     stranVisina = e.PageSettings.PrintableArea.Height; 

     fontHeight = font.GetHeight(); 

     //this works/prints 
     printDocument_PrintHeader(); 

     //this works/prints 
     printDocument_PrintDocumentInfo(); 

     if (firstPage) printDocument_PrintSupplierInfo();  

     //Lines that I take from DB, amount of this lines is variable //it only prints one page, then it stops printing 
     printDocument_PrintProductLines(e); 

     //Sum of lines 
     if(zadnjaStran) printDocument_printSum(); 

     //prints comment on document 
     if (zadnjaStran) printDocument_PrintComment(); 

     //footer 
     printDocument_PrintFooter(); 
    } 

    static void printDocument_PrintProductLines(PrintPageEventArgs e) 
    { 
     //I print some stuff here (header, etc..) 

     String stranArtikliVrstica = String.Empty; // string for one line of data 
     DataRow dataRow1 = null; 
     DataRow dr = null; 

     for(int i = 0; i < list.Count(); i++) 
     { 
      dr = list[i]; 
      dataRow1 = poglejBazo("SELECT ime, EM, opis FROM Sifrant WHERE ID = " + dr[2].ToString()).Tables[0].Rows[0]; 

      stranArtikliVrstica = String.Format("{0,-38} {1,10} {2,5} {3,9:C} {4,9:C}", dataRow1[0].ToString() + " - " + dataRow1[2].ToString(), dr[3].ToString(), dataRow1[1].ToString(), dr[4], Convert.ToInt16(dr[3]) * Convert.ToInt16(dr[4])); 

      list.Remove(dr); 

      graphic.DrawString(stranArtikliVrstica, font, brush, startX + offsetX, startY + offsetY); 
      offsetY += (int)font.GetHeight(); 

      //if there is less then 35 "lines" remaining, we have enough space for printing some other stuff, otherwise, that stuff doesn't print.. 
      if (list.Count() < 35) zadnjaStran = true; 
      else zadnjaStran = false; 

      if (offsetY > stranVisina - 50) 
      { 
       prvaStran = false; 
       stevecStrani++; 
       offsetY = 0; 
       e.HasMorePages = true; 
       return; 
      } 
     } 

    } 

所以，當我試圖打印文檔用單頁面，一切正常，但如果我嘗試打印多頁文檔，只打印第一頁（Header，DocumentInfo，SupplierInfo，ProductLines（80條左右的38行），Footer），然後再沒有更多頁面正在打印成PDF文件..）

我在做什麼錯？

PrintProductLines中的e參數有問題嗎？我怎樣才能告訴功能PrintProductLines，我想從原來的功能觸發HasMorePages？我知道我可以通過引用傳遞，但裁判關鍵字不會在我的情況下工作：S

編輯：

更改static void printDocument_PrintProductLines(ref PrintPageEventArgs e)和printDocument_PrintProductLines(ref e);拋出一個錯誤：

Error 2 Argument 1 must be passed with the 'ref' keyword
Error 1 The best overloaded method match for 'GZIG.globalClass.printDocument_PrintPostavke(ref System.Drawing.Printing.PrintPageEventArgs)' has some invalid arguments

你不應該將這樣的打印代碼放入一個靜態的全局類中。

此例程屬於將使用Graphics對象的類的實際實例。

private const int PAD = 4; 
private int m_Line, m_LinesToPrint; 
private Font m_Font; 
private PrintDocument m_Doc; 

private void print_Click(object sender, EventArgs e) { 
    using (var dlg = new PrintPreviewDialog()) { 
    if (m_Doc == null) { 
     throw new NullReferenceException("Create the document before trying to print it."); 
    } 
    dlg.Document = m_Doc; 
    m_Line = 0; 
    m_LinesToPrint = list.Count; 
    m_Font = new Font("Courier New", 14, FontStyle.Underline, GraphicsUnit.Point); 
    dlg.ShowDialog(); 
    } 
} 

private void printDocument1_PrintPage(object sender, PrintPageEventArgs e) { 
    float lineHeight = m_Font.GetHeight(e.Graphics) + PAD; 
    float yLineTop = e.MarginBounds.Top; 
    for (; m_Line < m_LinesToPrint; m_Line++) { 
    if (e.MarginBounds.Bottom < (yLineTop + lineHeight)) { 
     e.HasMorePages = true; 
     return; 
    } 
    DataRow dr = list[m_Line]; 
    DataRow row1 = poglejBazo("SELECT ime, EM, opis FROM Sifrant WHERE ID = " + dr[2].ToString()).Tables[0].Rows[0]; 
    string strText = String.Format("{0,-38} {1,10} {2,5} {3,9:C} {4,9:C}", dataRow1[0].ToString() + " - " + dataRow1[2].ToString(), dr[3].ToString(), dataRow1[1].ToString(), dr[4], Convert.ToInt16(dr[3]) * Convert.ToInt16(dr[4])); 
    // list.Remove(list[m_Line]) <= DO NOT DO THAT! 
    e.Graphics.DrawString(strText, m_Font, Brushes.Black, new PointF(e.MarginBounds.Left, yLineTop)); 
    yLineTop += lineHeight; 
    } 
    e.HasMorePages = false; 
}
