C#打印自动分页

[liangzhl]

我的是在winform窗口中放了个datagridview，要把里面的数据打印出来同时都是放在表格里的，我是自己画表格的，但是如果多出一页就不知道怎么处理了，求助？？？？

代码如下：
private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
Font font = new Font("Tahoma", 10, FontStyle.Regular);//设置画笔
Font font2 = new Font("宋体", 25, FontStyle.Bold);
Brush bru = Brushes.Blue;
Pen pen = new Pen(bru);
Graphics g = e.Graphics;
pen.Width = 1;
//设置各边距
float linesPerPage = 0;
//linesPerPage = e.MarginBounds.Height / 20;

int nLeft = e.PageSettings.Margins.Left / 2;
int nTop = e.PageSettings.Margins.Top - e.PageSettings.Margins.Left + 10;
int nRight = e.PageSettings.Margins.Right / 2;
int nBottom = e.PageSettings.Margins.Bottom;
int nWidth = e.PageSettings.PaperSize.Width - nRight - nLeft;
int nHeight = e.PageSettings.PaperSize.Height - nTop - nBottom;

g.DrawString(cmbcusname.SelectedItem.ToString() + dateTimePicker1.Value.Month.ToString() + "月份" + label5.Text, font2, bru, nLeft + 200, nTop + 50);

e.Graphics.DrawLine(pen, nLeft + 534, nTop + 95, nLeft + nWidth, nTop + 95);
e.Graphics.DrawLine(pen, nLeft + 534, nTop + 95, nLeft + 534, nTop + 130);
g.DrawString("贷款金额为：" + txtPrice.Text.Trim(), font, bru, nLeft + 535, nTop + 105);
e.Graphics.DrawLine(pen, nLeft + nWidth, nTop + 95, nLeft + nWidth, nTop + 130);

e.Graphics.DrawLine(pen, nLeft, nTop + 130, nLeft + nWidth, nTop + 130);
e.Graphics.DrawLine(pen, nLeft, nTop + 130, nLeft, nTop + 160);
g.DrawString("编号", font, bru, nLeft + 5, nTop + 135);
e.Graphics.DrawLine(pen, nLeft + 95, nTop + 130, nLeft + 95, nTop + 160);
g.DrawString("订单号", font, bru, nLeft + 105, nTop + 135);
e.Graphics.DrawLine(pen, nLeft + 195, nTop + 130, nLeft + 195, nTop + 160);
g.DrawString("货号", font, bru, nLeft + 205, nTop + 135);
e.Graphics.DrawLine(pen, nLeft + 295, nTop + 130, nLeft + 295, nTop + 160);
g.DrawString("材质", font, bru, nLeft + 305, nTop + 135);
e.Graphics.DrawLine(pen, nLeft + 410, nTop + 130, nLeft + 410, nTop + 160);
g.DrawString("规格", font, bru, nLeft + 420, nTop + 135);
e.Graphics.DrawLine(pen, nLeft + 534, nTop + 130, nLeft + 534, nTop + 160);
g.DrawString("单位", font, bru, nLeft + 535, nTop + 135);
e.Graphics.DrawLine(pen, nLeft + 575, nTop + 130, nLeft + 575, nTop + 160);
g.DrawString("数量", font, bru, nLeft + 580, nTop + 135);
e.Graphics.DrawLine(pen, nLeft + 615, nTop + 130, nLeft + 615, nTop + 160);
g.DrawString("单价", font, bru, nLeft + 620, nTop + 135);
e.Graphics.DrawLine(pen, nLeft + 665, nTop + 130, nLeft + 665, nTop + 160);
g.DrawString("金额", font, bru, nLeft + 670, nTop + 135);

e.Graphics.DrawLine(pen, nLeft, nTop + 160, nLeft + nWidth, nTop + 160);

int hj = 165;
for (int i = 0; i < dataGridView1.Rows.Count; i++)
{
e.Graphics.DrawLine(pen, nLeft, nTop + hj - 5, nLeft, nTop + hj + 22);
g.DrawString(dataGridView1.Rows[i].Cells[0].Value.ToString(), font, bru, nLeft + 5, nTop + hj + 4);

8楼说的，还是不行啊。郁闷啊~~~~

[小坏猪猪]

lz用水晶报表吧

[ddsxd19]

自己画？
可以数据导在excel上再打印出来～

[liangzhl]

我要的是直接就能打印出来的啊，水晶报表没用过，也不会用啊，所以就自己画了

[kaizi_sun]

count 是你每页打印行的记数
linesparpage是你每页要打的行数，自己大概计算下。
linNo是你dataGridView1读到的row index.
lineQty你总共需要打印的行数

while (count < linesPerPage && lineNo < lineQty)
{                      
  if (lineNo < dataGridView1.Rows.Count) //由于lineNo用于表中的下标值，因此需要加判断
    {   
    g.DrawString(dataGridView1.Rows[lineNo].Cells[1].Value.ToString(), font, bru, nLeft + 100, nTop + hj + 4); //这里是你的循环
                   
      count++;
    }
    lineNo++;
 }
//下面分页要放在循环之外
 if (lineQty > lineNo)
  {
     count = 0;
     printingPageNo++;
     e.HasMorePages = true;
     return;
   }
 else
  {
    count++;
    e.HasMorePages = false;
    lineNo = 0;
    lineQty = 0;
   }

你的意思是自动和纸张大小的匹配？为什么不用水晶报表

[liaoyukun111]

友情帮顶

[xtiu77]

if (barCodeStart <= barCodeEnd)//分页
{
e.HasMorePages = true;
}
else
{
e.HasMorePages = false;

}

楼上的可以说得清楚些吗？

[liangzhl]

for (int i = 0; i < pageRows; i++)
//////////////////////////////////////
但是如果DAG中并没有这么多行，比如只有10行，那么pageRows是20，运行是会出错的，因为DAG中就只有10行啊，其他的就找不到了，而i还是会在继续加1。我是直接用DAG中的数据来填充的
难道要在加个IF来判断是否pageRows大于DAV.Rows.Count。如果大的话就用你说的FOR.如果小就用i<dav.rows.count？？？不过这样看起来很不那个 啊

[xtiu77]

在for前面加

if(Rows.Count-index<pageRows)
{
pageRows=Rows.Count-index;
}

分页的思路就是这样.

[an_ding]

自己画的话问题很多的，楼主你的行数是固定啊，如果某一个单元格的数据比较多，放不下是不是就显不出来了？不能换行吧？

[liangzhl]

行数不是固定的，列数和宽度固定了，楼上的那你说应怎么解决啊？
