打印多页边距 [英] print multipage margin

问题描述

这是我的打印文档代码

  string  strDisplay =  印刷索引; 
 System.Drawing.Font fntString =  new 字体（  Times New Roman， 28 ，FontStyle.Bold）; 
 e.Graphics.DrawString（strDisplay，fntString，Brushes.Black， 180 ， 100 ） ; 
 
 fntString =  new  System.Drawing.Font（  Times New Roman， 12 ，FontStyle.Regular）; 
 e.Graphics.DrawString（  DESCRIPTION +   \ n +   -------------------------- +   \ n + textBox1.Text +   \ n  +   -------------------- ------ +   \ n + textBox1.Text +   \ n +  < span class =code-string> --------------------------，fntString，Brushes.Black， 70 ， 590 ）; 
  float  linesPerPage =  0 ; 
  float  yPosition =  590 ; 
  int  count =  0 ; 
  float  leftMargin =  70 ; 
  float  topMargin =  590 ; 
  string  line =  null ; 
字体printFont =  new  System.Drawing.Font（  Times New Roman， 8 ，FontStyle.Regular）; 
 SolidBrush myBrush =  new  SolidBrush（Color.Black）; 
 
 
 linesPerPage = e.MarginBounds.Height / printFont.GetHeight（e.Graphics）; 
  while （count <  linesPerPage&&（（line = myReader.ReadLine（ ））！=  null ））
 {
 yPosition = topMargin +（count * printFont.GetHeight（e.Graphics））; 
 e.Graphics.DrawString（line，printFont，myBrush，leftMargin，yPosition， new  StringFormat（））; 
 count ++; 
} 
 
  if （line！=  null ）
 {
 e.HasMorePages =  true ; 
} 
  else  
 {
 e.HasMorePages =  false ; 
 myBrush.Dispose（）; 
} 

第一页显示的textbox1内容开始上边距590，也在第二页打印也是上边距是590，我希望第一页上边距是590，第二页连续到顶部位置但不是它590



i卡在这里plz help

解决方案

你应该在页面级别上保持一个标志

  bool  isFirstPagePrinted =  false ; 

当第一次调用事件时
...

  if （！isFirstPagePrinted）
（
 yPosition =  590 ; 
 topMargin =  590 ; 
 isFirstPagePrinted =  true ; 
} 
  else  
 {
 yPosition =  100 ; 
 topMargin = < span class =code-digit> 10 0 ; 
} 

希望这个approch会有所帮助

你可以重置

 isFirstPagePrinted =  false ; 

点击打印按钮

快乐的编码！ ：）

Hi,

this is my print document code

string strDisplay = "Printing Index";
            System.Drawing.Font fntString = new Font("Times New Roman", 28, FontStyle.Bold);
            e.Graphics.DrawString(strDisplay, fntString, Brushes.Black, 180, 100);

fntString = new System.Drawing.Font("Times New Roman", 12, FontStyle.Regular);
            e.Graphics.DrawString("DESCRIPTION" + "\n" + "--------------------------" + "\n" + textBox1.Text + "\n" + "--------------------------" + "\n" + textBox1.Text + "\n" + "--------------------------", fntString, Brushes.Black, 70, 590);
float linesPerPage = 0;
            float yPosition = 590;
            int count = 0;
            float leftMargin = 70;
            float topMargin = 590;
            string line = null;
            Font printFont = new System.Drawing.Font("Times New Roman", 8, FontStyle.Regular);
            SolidBrush myBrush = new SolidBrush(Color.Black);


            linesPerPage = e.MarginBounds.Height / printFont.GetHeight(e.Graphics);
            while (count < linesPerPage && ((line = myReader.ReadLine()) != null))
            {
                yPosition = topMargin + (count * printFont.GetHeight(e.Graphics));
                e.Graphics.DrawString(line, printFont, myBrush, leftMargin, yPosition, new StringFormat());
                count++;
            }

            if (line != null)
            {
                e.HasMorePages = true;
            }
            else
            {
                e.HasMorePages = false;

解决方案

you should maintain a flag on page level

bool isFirstPagePrinted = false;

when first time event called...

if(!isFirstPagePrinted)
(
  yPosition = 590;
  topMargin = 590;
  isFirstPagePrinted = true;
}
else
{
  yPosition = 100;
  topMargin = 100;
}

Hope this approch will be helpful
you can reset

isFirstPagePrinted = false;

on click of your "print" button
Happy coding! :)
