add multiple pages in C# - c#

I'm writing a program in C# which takes information of items from Listview and print it based on the quantity of these items. My problem is that I would like to print a document in multiple pages in c#.
Here is my code:
private void printDocument1_PrintPage(object sender, PrintPageEventArgs e)
{
//frame
e.Graphics.DrawRectangle(Pens.Black, 30, 30, 757, 1080);
//rows
e.Graphics.DrawLine(Pens.Black, 30, 184, 787, 184);
e.Graphics.DrawLine(Pens.Black, 30, 338, 787, 338);
e.Graphics.DrawLine(Pens.Black, 30, 492, 787, 492);
e.Graphics.DrawLine(Pens.Black, 30, 646, 787, 646);
e.Graphics.DrawLine(Pens.Black, 30, 800, 787, 800);
e.Graphics.DrawLine(Pens.Black, 30, 955, 787, 955);
//columns
e.Graphics.DrawLine(Pens.Black, 282, 30, 282, 1110);
e.Graphics.DrawLine(Pens.Black, 534, 30, 534, 1110);
int rows_loc = 35;
int cols_loc = 70;
int lable_index = 0;
foreach (ListViewItem item in listView1.Items)
{
for (int quantity = 1; quantity < (Convert.ToInt32(item.SubItems[1].Text) + 1); quantity++)
{
Font font = new System.Drawing.Font("Arial", 16);
SolidBrush black = new SolidBrush(Color.Black);
Zen.Barcode.Code128BarcodeDraw barcode1 = Zen.Barcode.BarcodeDrawFactory.Code128WithChecksum;
Image barcode_image = barcode1.Draw(item.SubItems[2].Text, 20);
e.Graphics.DrawImage(barcode_image, 40f + cols_loc, 29f + rows_loc);
e.Graphics.DrawString(item.Text, font, black, 60f + cols_loc, 0f + rows_loc);
lable_index++;
row_index = (int)(lable_index / 3);
col_index = lable_index % 3;
rows_loc = 35 + ((row_index) * 155);
cols_loc = 70 + (250 * col_index);
if (rows_loc >= e.PageSettings.PrintableArea.Height)
{
e.HasMorePages = true;
rows_loc = 35;
return;
}
else
{
e.HasMorePages = false;
}
}
}
}
But got the page looks like the figure below with infinite number of pages! I would be very appreciated if someone can help.
Thanks

Print Preview making Issue in C#

when I click on print preview button. it shows my listed items. but when I close print preview screen and add some more items and click on print preview. it shows only that items which I enter later. I clear my old added Items.
here is my code which I'm trying
private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
e.Graphics.DrawString("Date: " + DateTime.Now.ToShortDateString(), new Font("Calibri", 11, FontStyle.Regular), Brushes.Black, new Point(300, 150));

int yPos = 200;
int xPos = 20;
int brandyPos = 180;
for (int i = numberOfItemsPrintedSoFar; i < beltlist.Count; i++)
{
numberOfItemsPerPage++;
if (numberOfItemsPerPage <= 15 && count <= 3)
{
numberOfItemsPrintedSoFar++;
if (numberOfItemsPrintedSoFar <= beltlist.Count)
{
e.Graphics.DrawString(beltlist[i].BrandName, new Font("Calibri", 11, FontStyle.Regular), Brushes.Black, new Point(xPos, brandyPos));
brandyPos = yPos + 20;
e.Graphics.DrawString(beltlist[i].BeltSize.ToString() + "--" + beltlist[i].QTY.ToString(), new Font("Calibri", 11, FontStyle.Regular), Brushes.Black, new Point(20, yPos));
yPos += 20;
}
else
{

}
}
else
{
count++;
yPos = 180;
xPos += 150;
numberOfItemsPerPage = 0;
if (count > 3)

Coding a class with protected variables to be access by another method

I am having problems creating a protected variable that can be access and updated by an external method.
In other words, I have got a print method that prints multiple pages.
I needs an external variable to initialize this method and keep track of the pages.
Is it possible someone could get me started in coding this class? as I knowledge on OOP is limited
Below is the print method
Thanks in advance
private void printDocument1_PrintPage(object sender, PrintPageEventArgs e)
{
Graphics graphics = e.Graphics;
int ypos = 78;
Font f1 = new Font("Arial", 14, FontStyle.Bold, GraphicsUnit.Pixel);
Brush brush = new SolidBrush(Color.LightSlateGray);
graphics.FillRectangle(brush, new Rectangle(10, 10, 770, 50));
Pen blackpen = new Pen(Color.Black);
Pen graypen = new Pen(Color.LightGray);
Pen redpen = new Pen(Color.Red);
graphics.DrawRectangle(blackpen, new Rectangle(10, 10, 770, 50));
Brush B = new SolidBrush(listView1.ForeColor);
graphics.DrawLine(blackpen, 10, 10, 10, 1132);
graphics.DrawString("FORENAME", f1, Brushes.Black, new Point(20, 25));
graphics.DrawLine(blackpen, 130, 10, 130, 1132);
graphics.DrawString("SURNAME", f1, Brushes.Black, new Point(140, 25));
graphics.DrawLine(blackpen, 290, 10, 290, 1132);
graphics.DrawString("EXT.", f1, Brushes.Black, new Point(300, 25));
graphics.DrawLine(blackpen, 380, 10, 380, 1132);
graphics.DrawString("JOB TITLE", f1, Brushes.Black, new Point(410, 25));
graphics.DrawLine(blackpen, 780, 10, 780, 1132);
int[] X = { 15, 140, 300, 390, 720 };
int Y = 60;
f1 = listView1.Font;
for (int I = 0; I < listView1.Items.Count; I++){
for (int J = 0; J < listView1.Items[I].SubItems.Count - 1; J++){
graphics.DrawString(listView1.Items[I].SubItems[J].Text, f1, B, X[J], Y);
}
}
Y += f1.Height;
graphics.DrawLine(graypen, 10, ypos, 780, ypos);
ypos = ypos + 17;
if (ypos > 1132){
e.HasMorePages = true;
return;
}
graphics.Dispose();
}
Try below function, and call print event
public void PrintDocument()
{
try
{
PrintDocument pd = new PrintDocument();
pd.PrintPage += new PrintPageEventHandler
(this.printDocument1_PrintPage);
pd.Print();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}

Well, I was a bit bored. I'll assume that the object is going to move in a 45 degrees trajectory,and that when it collides with the bounds it would change by 90º.
What I would do (this is a very simple solution) is, first of all, define the direction in both axes in which i want the "smiley" to move,the step in each timer tick, the position of the center and the size of the object, something like:
int xpos = 0;
int ypos = 130;
int step = 10;
int width = 250;
int height = 250;
int directionX = +1;
int directionY = -1;
The timer would just increase the x and y positions:
private void timer1_Tick(object sender, EventArgs e)
{
xpos += 10*directionX;
ypos += 10*directionY;
checkBounds(); //This would check if the object collides with the bounds
this.Invalidate();
}
The checkBounds method check if the object collides with the bounds:
private void checkBounds()
{
if (ypos < 0 + step || ypos + height+ step > ClientRectangle.Height)
{
directionY *= -1;
}
if (xpos < 0 + step || xpos + width + step > ClientRectangle.Width)
{
directionX *= -1;
}
}
Finally, the Paint method is similar to yours, just adjusting some values:
private void Form2_Paint(object sender, PaintEventArgs e)
{
Graphics g = e.Graphics;
Pen myPen = new Pen(Brushes.Red, 7);
Pen myPen2 = new Pen(Brushes.Green, 7);
int endX = this.ClientRectangle.Width;
int endY = this.ClientRectangle.Height;
int xCenter = this.ClientRectangle.Left + (this.ClientRectangle.Width / 2);
int yCenter = this.ClientRectangle.Top + (this.ClientRectangle.Height / 2);
Pen circlePen = new Pen(Brushes.Black, 9);
Font myFont = new Font("Monotype Corsiva", 43, FontStyle.Bold);
g.DrawString("Happy Face", myFont, Brushes.Aqua, 300, 25);
g.DrawEllipse(circlePen, xpos, ypos, 250, 250);
g.FillEllipse(Brushes.PeachPuff, xpos, ypos, 250, 250);
g.DrawEllipse(circlePen, xpos + 65, ypos -130 + 200, 20, 35);
g.FillEllipse(Brushes.Black, xpos + 65, ypos-130 + 200, 20, 35);
g.DrawEllipse(circlePen, xpos + 160, ypos-130 + 200, 20, 35);
g.FillEllipse(Brushes.Black, xpos + 160, ypos-130 + 200, 20, 35);
g.DrawArc(circlePen, xpos + 60, ypos-130 + 215, 130, 120, 35, 115);
}
This code could be highly improved, but this may help you think how it should be done. Hope it helps.

how to print only the checked rows from a datagridview in c#

I have a Datagridview it has a checkboxcolumn!
when the data is loaded for standard all rows get checked! but i need to uncheck some of them and them, send it's values to a var and print it!
is it possible?
Exemple:
--------------------------------------------------------------
ColumnCheckBox | Column1 | Column2 | Column3
--------------------------------------------------------------
checked | 1251000014 | portraitx | U$ 125.00
checked | 1251000021 | notebooky | U$ 899.96
unchecked | 1265888512 | tabletx | U$ 899.96
checked | 1251444251 | iphoness | U$ 566.26
unchecked | 1255222142 | opticalreader | U$ 99.99
I want to get the values of the CHECKED Rows and send to a var and the print it! the main is ...how to send this values to a var?
thankx in advance!
Print all checked rows in a page:
private void printDocument1_PrintPage(object sender, PrintPageEventArgs e)
{
//Find all checked rows
var allCheckedRows = this.myDataGridView.Rows.Cast<DataGridViewRow>()
.Where(row => (bool?)row.Cells[0].Value == true)
.ToList();
//create a stringBuilder that will contain the string for all checked rows
var builder = new StringBuilder();
//For each checked row, create string presentation of row and add to output stringBuilder
allCheckedRows.ForEach(row =>
{
//Create an array of all cell value of a row to then concatenate them using a separator
var cellValues = row.Cells.Cast<DataGridViewCell>()
.Where(cell => cell.ColumnIndex > 0)
.Select(cell => string.Format("{0}", cell.Value))
.ToArray();
//Then joiconcatenate values using ", " as separator, and added to output
builder.AppendLine(string.Join(", ", cellValues));
//Here instead of adding them to the stringBuilder, you can add int to another list.
});
//Print the output string
e.Graphics.DrawString(builder.ToString(),
this.myDataGridView.Font,
new SolidBrush(this.myDataGridView.ForeColor),
new RectangleF(0, 0, this.printDocument1.DefaultPageSettings.PrintableArea.Width, this.printDocument1.DefaultPageSettings.PrintableArea.Height));
}
Output:
1251000014, portraitx, U$ 125.00
1251000021, notebooky, U$ 899.96
1251444251, iphoness, U$ 566.26
Print each checked row in a separate page:
private int currentPrintingRowIndex = 0;
private void printDocument1_PrintPage(object sender, PrintPageEventArgs e)
{
var allCheckedRows = this.myDataGridView.Rows.Cast<DataGridViewRow>()
.Where(row => (bool?)row.Cells[0].Value == true)
.ToList();
if (allCheckedRows.Count > currentPrintingRowIndex)
{
var builder = new StringBuilder();
var currentCheckedRow = allCheckedRows[currentPrintingRowIndex];
var cellValues = currentCheckedRow.Cells.Cast<DataGridViewCell>()
.Where(cell => cell.ColumnIndex > 0)
.Select(cell => string.Format("{0}", cell.Value))
.ToArray();
builder.AppendLine(string.Join(", ", cellValues));
e.Graphics.DrawString(builder.ToString(),
this.myDataGridView.Font,
new SolidBrush(this.myDataGridView.ForeColor),
new RectangleF(0, 0, this.printDocument1.DefaultPageSettings.PrintableArea.Width, this.printDocument1.DefaultPageSettings.PrintableArea.Height));
currentPrintingRowIndex += 1;
e.HasMorePages = allCheckedRows.Count > currentPrintingRowIndex;
}
}
Output:
A document with 3 pages:
Page1 content: 1251000014, portraitx, U$ 125.00
Page2 content: 1251000021, notebooky, U$ 899.96

Print with Task

I'm creating a label with Graphics and printing it with PrintDocument, before i didn't had any problems because the information on the label was repeated multiple times so i would just set copies and everything would work fine.
But now each label has a different information so it freezes the ui because i have to loop PrintDocument.Print() multiple times instead of setting copies.
i tried:
Task t = new Task(() =>
{
for (int i = 0; i < Copies; i++)
{
printDocument1.Print();
Label_Copies++;
}
});
t.Start();
I'm drawing the label on printDocument1_PrintPage with this code:

but it doesn't work is there a way to fix it?
-the information comes from the ui
-500~ labels
-the only information that changes from label to label in those copies is

its basically a counter for the label number...
As I see it, your code, if we ignore the printer's spooling side, is pure WinForms UI.
Since that the work is multiplied, let's say by a 100 copies, it becomes too much Continous UI.
Tasking isn't helping you because I think the printing side is "fire and forget", so even if the printing took 30 seconds per sticker, the printing side would return immediately, and let the UI start it's heavy work on the next sticker, almost immediately after it finishes the last one.
let's say the UI has to work 1 second per sticker, you are looking at a 100 seconds UI blocking...
My suggestion:
Rely on the fact that the printing behind takes 20 seconds: Launch the printing using a timer instead of a loop. Set it to 5, 10 or 20 seconds (match with your printer's speed). Each time you will fire the timer, it will UI process 1 sticker only, and then rest in peace for 5, 10, or 20 seconds...
