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));
e.Graphics.DrawString("Customer Name: " + customername.Text.Trim(), new Font("Calibri", 11, FontStyle.Regular), Brushes.Black, new Point(20, 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
{
e.HasMorePages = false;
}
}
else
{
count++;
yPos = 180;
xPos += 150;
numberOfItemsPerPage = 0;
if (count > 3)
{
e.HasMorePages = true;
xPos = 20;
count = 1;
return;
}
}
}
}

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);
}
}

printing on a document c# .net

i am trying to print a invoice from application for my dads business, i am using the following code to print the invoice.
My attempt is below:
{
int y = 470;
while (i < dataGridView1.RowCount)
{
e.Graphics.DrawString(dataGridView1.Rows[i].Cells["ProductName"].Value.ToString(), DefaultFont, Brushes.Black, new Point(35, y));
e.Graphics.DrawString(dataGridView1.Rows[i].Cells["Desc"].Value.ToString(), new Font("Arial", 15, FontStyle.Bold), Brushes.Black, new Point(250, y));
e.Graphics.DrawString(dataGridView1.Rows[i].Cells["Quantity"].Value.ToString(), new Font("Arial", 15, FontStyle.Bold), Brushes.Black, new Point(600, y));
e.Graphics.DrawString(dataGridView1.Rows[i].Cells["UnitPrice"].Value.ToString(), new Font("Arial", 15, FontStyle.Bold), Brushes.Black, new Point(650, y));
e.Graphics.DrawString(dataGridView1.Rows[i].Cells["Tax"].Value.ToString(), new Font("Arial", 15, FontStyle.Bold), Brushes.Black, new Point(700, y));
e.Graphics.DrawString(dataGridView1.Rows[i].Cells["Total"].Value.ToString(), new Font("Arial", 15, FontStyle.Bold), Brushes.Black, new Point(650, y));
y = y + 20;
if (y >= pageHeight)
{
e.HasMorePages = true;
y = 0;
i++;
return;
}
else
{
e.HasMorePages = false;
}
i++;
}
}
i here is a global variable
private int i = 0;
when i click on preview button i get the output as expected but when i print it on paper only the content in the while loop is not printed. i tried using a local variable instead j of global variable as shown below and it worked.
for (int j=0; j < dataGridView1.RowCount; j++)
{
e.Graphics.DrawString(dataGridView1.Rows[j].Cells["ProductName"].Value.ToString(), DefaultFont, Brushes.Black, new Point(35, y));
e.Graphics.DrawString(dataGridView1.Rows[j].Cells["Desc"].Value.ToString(), new Font("Arial", 15, FontStyle.Bold), Brushes.Black, new Point(250, y));
e.Graphics.DrawString(dataGridView1.Rows[j].Cells["Quantity"].Value.ToString(), new Font("Arial", 15, FontStyle.Bold), Brushes.Black, new Point(600, y));
e.Graphics.DrawString(dataGridView1.Rows[j].Cells["UnitPrice"].Value.ToString(), new Font("Arial", 15, FontStyle.Bold), Brushes.Black, new Point(650, y));
e.Graphics.DrawString(dataGridView1.Rows[j].Cells["Tax"].Value.ToString(), new Font("Arial", 15, FontStyle.Bold), Brushes.Black, new Point(700, y));
e.Graphics.DrawString(dataGridView1.Rows[j].Cells["Total"].Value.ToString(), new Font("Arial", 15, FontStyle.Bold), Brushes.Black, new Point(650, y));
y = y + 20;
}
but i don't know how to add new pages if the item to be included exceeds the page height. please some help.

after iterating through the code step by step i found that the code tp print the preview is run again while printing the form. so i just had to initialize the i value to 0 so that it starts printing from the beginning.
here is the code which solved it
int j;
for (j=i; j < dataGridView1.RowCount && y<e.MarginBounds.Bottom; j++)
{
e.Graphics.DrawString(e.MarginBounds.Bottom.ToString(), DefaultFont, Brushes.Black, new Point(100, y));
e.Graphics.DrawString(dataGridView1.Rows[j].Cells["ProductName"].Value.ToString(), DefaultFont, Brushes.Black, new Point(35, y));
e.Graphics.DrawString(dataGridView1.Rows[j].Cells["Desc"].Value.ToString(), new Font("Arial", 15, FontStyle.Bold), Brushes.Black, new Point(220, y));
e.Graphics.DrawString(dataGridView1.Rows[j].Cells["Quantity"].Value.ToString(), new Font("Arial", 15, FontStyle.Bold), Brushes.Black, new Point(770, y));
e.Graphics.DrawString(dataGridView1.Rows[j].Cells["UnitPrice"].Value.ToString(), new Font("Arial", 15, FontStyle.Bold), Brushes.Black, new Point(620, y));
e.Graphics.DrawString(dataGridView1.Rows[j].Cells["Tax"].Value.ToString(), new Font("Arial", 15, FontStyle.Bold), Brushes.Black, new Point(670, y));
e.Graphics.DrawString(dataGridView1.Rows[j].Cells["Total"].Value.ToString(), new Font("Arial", 15, FontStyle.Bold), Brushes.Black, new Point(720, y));
y = y + 20;
}
if (j < dataGridView1.RowCount)
{
e.HasMorePages = true;
i=j;
}
else
{
e.HasMorePages = false;
i = 0;
}

C# printing issue - printing datagridview data - 2,3,4 times the printing slowing down --Windows Form

I fill up a datagridview and after that I print out the list from there some extra fix string fields. The first two printing finishing fast but after that 3-4 is slowing down very much(sometimes it freezing).
I think some buffer or something fills up and i have to empty it but how? If I tried to print via pdf printer the first file size is normal ~200KB second is 1MB and the third is 4-6MB the fourth is so big it is freezing.
It is only one page maximum two page long list. Can someone help me to find the problem and offer a solution or more?

I think that you are not doing it right. It should go something like this:
private void MyPrintDocument_PrintPage(object sender,
System.Drawing.Printing.PrintPageEventArgs e)
{
bool more = DrawItems(e.Graphics);
if (more == true)
e.HasMorePages = true;
}
So, after PrintDocument Print event, you call your method to draw items, and it tracks last painted item in variable outside of the method, so when it is called again to know where to start from. And when it comes to item that should go to next page, it returns true.
