Here is an absolutely minimal code example.
It prints all rows of a dgv, including simple headers and footers..
You need to add a PrintDocument printDocument1 to your form.
Also a Button cb_printPreview.
// a few variables to keep track of things across pages:
int nextPageToPrint = -1;
int linesOnPage = -1;
int linesPrinted = -1;
int maxLinesOnPage = -1;
private void printDocument1_PrintPage(object sender,
System.Drawing.Printing.PrintPageEventArgs e)
{
// for each fresh page:
linesOnPage = 0;
nextPageToPrint++;
// a short reference to the DataGridView we want to print
DataGridView DGV = yourDataGridView;
// I prefer mm, pick your own unit!
e.Graphics.PageUnit = GraphicsUnit.Millimeter;
// I want to print the columns at these fixed positions
// the first one is the left margin,
// the last one a dummy at the right page margin
int[] tabStops = new int[4] {15, 30, 100, 190};
// I want only one column to be right-aligned:
List<int> rightAlignedCols = new List<int>() { 1 };
// we need to keep track of the horizontal position
// this is also the top margin:
float y = 35f;
// we add a little space between the lines:
float leading = 1.5f;
// we will need to measure the texts we print:
SizeF size = Size.Empty;
// we use only one font:
using (Font font = new Font("Consolas", 13f))
{
// a simple header:
e.Graphics.DrawString("List " + printDocument1.DocumentName,
font, Brushes.Black, 50, y);
y += size.Height + 15;
// I loop over the all rows:
for (int row = linesPrinted; row < DGV.Rows.Count; row++)
{
// I print a light gray bar over every second line:
if (row % 2 == 0)
e.Graphics.FillRectangle(Brushes.Gainsboro,
tabStops[0], y - leading / 2, e.PageBounds.Width - 25, size.Height);
// I print all (3) columns in black, unless they're empty:
for (int col = 0; col < DGV.ColumnCount; col++)
if (DGV[0, row].Value != null)
{
string text = DGV[col, row].FormattedValue.ToString();
size = e.Graphics.MeasureString(text, font, 9999);
float x = tabStops[col];
if (rightAlignedCols.Contains(col) )
x = tabStops[col + 1] - size.Width;
// finally we print an item:
e.Graphics.DrawString(text, font, Brushes.Black, x, y);
}
// advance to next line:
y += size.Height + leading;
linesOnPage++;
linesPrinted++;
if (linesOnPage > maxLinesOnPage) // page is full
{
e.HasMorePages = true; // more to come
break; // leave the rows loop!
}
}
e.Graphics.DrawString("Page " + nextPageToPrint, font,
Brushes.Black, tabStops[3] -20, y + 15);
}
}
private void cb_printPreview_Click(object sender, EventArgs e)
{
PrintPreviewDialog PPVdlg = new PrintPreviewDialog();
PPVdlg.Document = printDocument1;
PPVdlg.ShowDialog();
}
private void printDocument1_BeginPrint(object sender,
System.Drawing.Printing.PrintEventArgs e)
{
// create a demo title for the page header:
printDocument1.DocumentName = " Suppliers as of "
+ DateTime.Now.ToShortDateString();
// initial values for a print job:
nextPageToPrint = 0;
linesOnPage = 0;
maxLinesOnPage = 30;
linesPrinted = 0;
}
The actual printing can be triggered from the PrintPreviewDialog.
There is also a PrintDialog and a PrintPreview control for more options.
Obviously one can add many more things, including graphics, multiple fonts etc, but this should give you an idea.. For full tutorials please look refer to the WWW & MSDN!
