datagridview 打印
有没有人会datagridview 打印，需要调用打印机纸张设置页面。不同的纸张有不同的打印预览。

你的难点是打印DGV还是打印设置或者预览？
打dgv有点复杂，要画线，要算位置，要考虑是不是需要自动伸缩列高等。
打印设置，.NET有组件，调一下赋值给printdoc对象即可
预览的话，画到printpreview组件里即可

[解决办法]
新建一个winform窗体，工具栏里你就能看到：
PrintPreview控件
PageSetupDialog控件～
[解决办法]
可以使用长江支流的打印组件, 或者参考C# WinForm开发系列 - DataGrid/DataGridView

用printDocument

关注 我只做过普通打印 没 写过带 设置的

我一般都是导到excel里，呵呵

你给的分真少～打印DataGridView
- C# code
private void DrawDataGridView(DataGridView d, Graphics g, ref int startRowIndex) { Rectangle r = GetControlRect(d); if (d.ColumnHeadersDefaultCellStyle.BackColor != Color.White) g.FillRectangle(new SolidBrush(d.ColumnHeadersDefaultCellStyle.BackColor), r.X, r.Y, r.Width, d.ColumnHeadersHeight); float colWidth = 0; for (int j = 0; j < d.Columns.Count; j++) { if (d.Columns[j].Visible) colWidth += d.Columns[j].Width; //((float)d.Columns[i].Width /(float)d.Width ) } int startPx = r.X; int[] ColumnWidth = new int[d.Columns.GetColumnCount(DataGridViewElementStates.Visible)]; DataGridViewColumn column = d.Columns.GetFirstColumn(DataGridViewElementStates.Visible); int idx = 0; while (column != null) { Rectangle rtxt = new Rectangle(startPx, r.Y, (int)(((float)column.Width / colWidth) * d.Width), d.ColumnHeadersHeight); ColumnWidth[idx] = rtxt.Width; startPx += rtxt.Width; SizeF sf = g.MeasureString(column.HeaderText, d.ColumnHeadersDefaultCellStyle.Font, rtxt.Width); switch (d.ColumnHeadersDefaultCellStyle.Alignment) { case DataGridViewContentAlignment.BottomCenter: case DataGridViewContentAlignment.MiddleCenter: case DataGridViewContentAlignment.TopCenter: if (sf.Width <= rtxt.Width && sf.Height <= rtxt.Height) { rtxt = new Rectangle(rtxt.X + (rtxt.Width - (int)sf.Width) / 2, rtxt.Y + (rtxt.Height - (int)sf.Height) / 2, (int)sf.Width + 1, (int)sf.Height + 1); } break; default: if (sf.Height < rtxt.Height) { rtxt = new Rectangle(rtxt.X, rtxt.Y + (rtxt.Height - (int)sf.Height) / 2, (int)sf.Width + 1, (int)sf.Height + 1); } break; } g.DrawString(column.HeaderText, d.ColumnHeadersDefaultCellStyle.Font, new SolidBrush(d.ColumnHeadersDefaultCellStyle.ForeColor), rtxt); column = d.Columns.GetNextColumn(column, DataGridViewElementStates.Visible, DataGridViewElementStates.None); idx++; } if (startRowIndex < 0 || startRowIndex >= d.Rows.Count) return; SolidBrush cellcolor = new SolidBrush(d.DefaultCellStyle.ForeColor); //for (int i = 0; i < rowCount; i++) int i = 0; int h1 = d.ColumnHeadersHeight + r.Top; while (h1 <= r.Bottom) { if (i + startRowIndex >= d.Rows.Count) { if (h1 + d.RowTemplate.Height < r.Bottom) { g.DrawLine(_pen, r.X, h1, r.Right, h1); h1 += d.RowTemplate.Height; continue; } else break; } int maxh = d.RowTemplate.Height; column = d.Columns.GetFirstColumn(DataGridViewElementStates.Visible); while (column != null) { DataGridViewCell dvc = d.Rows[i + startRowIndex].Cells[column.Index]; string s = dvc.FormattedValue.ToString(); SizeF sf = g.MeasureString(s, dvc.Style.Font == null ?
