Hello,

I have a little problem(or else I wouldnt be asking here :)) with saving pagesetup in pagesetupdialog and then goint to print option which will use those pagestupdialog settings

I have this code in pagesetupdialog

private void btnPageSetup_Click(object sender, EventArgs e)
        {            
            PrintDocument printDocument1 = new PrintDocument();

            printDocument1.PrintPage += new PrintPageEventHandler(this.printDocument1_PrintPage);

            PageSetupDialog pageSetup = new PageSetupDialog();

            pageSetup.Document = printDocument1;

            pageSetup.PageSettings = printDocument1.DefaultPageSettings;
                        
            string strText = "";
            
            foreach (object x in listBox1.Items)
            {                
                strText = strText + x.ToString() + "\n";
            }

            myReader = new StringReader(strText);

            if (pageSetup.ShowDialog() == DialogResult.OK)
            {                
                printDocument1.DefaultPageSettings = pageSetup.PageSettings;
            }
        }

and this also

private void btnPrint_Click(object sender, EventArgs e)
        {            
            printDialog1.Document = printDocument1;

            string strText = "";
            foreach (object x in listBox1.Items)
            {
                strText = strText + x.ToString() + "\n";
            }

            myReader = new StringReader(strText);
            if (printDialog1.ShowDialog() == DialogResult.OK)
            {
                this.printDocument1.Print();
            }

        }

so I need to to print document based on pagesetupdialog settings, but I am missing something
