关于PrintDocument打印多页的问题

[newtypebao]

首先,新建一个PrintDocument

System.Drawing.Printing.PrintDocument pd3 = new PrintDocument();
pd3.PrintPage += new PrintPageEventHandler(pd3_PrintPage);
PrintPreviewDialog printPreviewDialog3 = new PrintPreviewDialog();
printPreviewDialog3.Document = pd3;
printPreviewDialog3.ShowDialog();

然后在这个pd3里绘图

private void pd3_PrintPage(object sender, PrintPageEventArgs e)
{

//我先设置要绘制文字的样式
Font sampletitlefont = new Font("宋体", 12, FontStyle.Bold | FontStyle.Underline);

//第一次绘制文字位置50,450,显示正常
e.Graphics.DrawString("我要输出的文字_1", sampletitlefont, Brushes.Black, new Point(50, 450));

//第二次绘制文字位置50, 1450,显然超过了PrintDocument一页的页面范围,所以没有显示
e.Graphics.DrawString("要输出的文字_2", sampletitlefont, Brushes.Black, new Point(50, 1450));
}



我想要请教的是,如何进行PrintDocument第二页的绘制?

起初我以为把文字坐标y的数字设的大点,便可以自动打印到第二页上,但是
事实证明,此方法无效...如果坐标设置超过此页范围,将不被显示.
那如何才能把图绘制到第二页上呢?第三页上呢。..?


ps:我曾经试过在pd3_PrintPage里设置e.HasMorePages = true;
但是还是不成功,这个操作会把第一页打印无数次...仍然没有我想要的第二页的内容.
还请高手指点,谢谢!

能不能顺便...简单的说下 如何绘制第二页饿。..

关于页数的问题
我只看到最下面的代码
if(currentPageIndex<pageCount)
{
e.HasMorePages=true;
}
else
{
e.HasMorePages=false;
this.currentPageIndex=0;

}
是和分页有关系的
我试过e.HasMorePages=true;
但是还是不成功,这个操作会把第一页打印无数次...仍然没有我想要的第二页的内容.

在打印第一页的时候要判断是否存在第二页，如果存在则要添加如下代码：e.HasMorePages=true;
还有就是要注意变量在打印的时候要初始化其值.
