用C＃在printdocument中打印更多页面。 [英] printing more pages in printdocument in C#.

问题描述

我想用listDocument打印listview 中的所有列表项。



我的打印预览如：

Item1

------

Item2

------

Item3

------

等......



我写了这段代码： -

I want to print all list items from listview with printDocument.

My print preview like :
Item1
------
Item2
------
Item3
------
so on....

I wrote this code :-

private void printDocument2_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
        {
            int yPos = 140;
            //bool more = true;
            foreach (ListViewItem xItem in listView1.Items)
            {
                e.Graphics.DrawString(xItem.SubItems[0].Text, new Font("Arial", 8.5f), Brushes.Black, 50, yPos);
                e.Graphics.DrawString(xItem.SubItems[1].Text, new Font("Arial", 8.5f), Brushes.Black, 380, yPos);
                e.Graphics.DrawString(xItem.SubItems[2].Text, new Font("Arial", 8.5f), Brushes.Black, 500, yPos);
                e.Graphics.DrawString(xItem.SubItems[3].Text, new Font("Arial", 8.5f), Brushes.Black, 500, yPos);
                yPos += 13;
                e.Graphics.DrawLine(Pens.Black, 50, yPos, 650, yPos);
            }
            e.HasMorePages = true;
        }

和printpreview代码是： -

and printpreview code is :-

PrintPreviewDialog PPD = new PrintPreviewDialog();
            PPD.Document = printDocument2;
            PPD.Document.DefaultPageSettings.PaperSize = new System.Drawing.Printing.PaperSize("PaperA4", 826, 1169);
            PPD.Document.PrinterSettings.DefaultPageSettings.PaperSize = new System.Drawing.Printing.PaperSize("PaperA4", 826, 1169);
            //PPD.MdiParent = Application.OpenForms[0];
            PPD.Show();

当此代码运行时添加了无限文档..



我在谷歌搜索，找到计算字符串高度的东西，并与printDocument图形MarginBounds进行比较。

但在我的情况下如何计算和打印更多页面？ ??



感谢高级...

推荐答案

您好，

这里有一个打印多页的例子。

Hello,
here one example for printing multiple pages .

int count = 0;//this variable is for total number of items in the list or array
    int i = 0;//this variable is  for no of item per page


    private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
    {
        float currentY = 10;// declare  one  variable for height measurment
        e.Graphics.DrawString("Animesh", DefaultFont, Brushes.Black, 100, currentY);//this will print one string in every page of the document
        while (count <= 300) // check the number of items
        {
            e.Graphics.DrawString(count.ToString(), DefaultFont, Brushes.Black, 10, currentY); //print each item
            currentY += 20; // set a gap between every item
            count += 1; //increment count by 1
            if (i < 50) // if  the number of item(per page) is less than 50 
            {
                i += 1; // increment i by +1
                e.HasMorePages = false; // set the HasMorePages property to false , so that no other page will not be added

            }
            else // if the number of item(per page) is more than 50
            {

                i = 0;           // initiate i to 0 .
                e.HasMorePages = true;
                return;
            }

        }

    }

谢谢
