Question

I want to create dynamic PDF document pages as per my record. Please help me.

I want to print 3 records per page.

string[] collection = {
    "vivek", "kashyap", "viral", "darshit", "arpit", "sameer", "vanraj"
};

PdfDocument pdfDoc = new PdfDocument();

int records = collection.Length;
int perpage = 3;
int pages = (int)Math.Ceiling((double)records / (double)perpage);


for (int p = 0; p < pages; p++)
{          
    PdfPage pdfPage = new PdfPage();
    pdfPage.Size = PageSize.Letter;
    pdfDoc.Pages.Add(pdfPage);
    XFont NormalFont = new XFont("Helvetica", 10, XFontStyle.Regular);

    using (var pdfGfx = XGraphics.FromPdfPage(pdfPage))
    {
        for (int i = 0,next = 100; i < collection.Length; i++)
        {
            pdfGfx.DrawString( "Name : " + collection[i].ToString()
                             , NormalFont, XBrushes.Black, 55, next
                             , XStringFormats.Default);
            next += 20;
        }
    }
}

Answer 1

I assume the code as you have presented it is showing the same top entries? What you need to do is maintain the start of each 3 entries as you move from page to page. I have called this variable idx and updated your code below (note I haven’t actually compiled it except in my head).

string[] collection = { "vivek", "kashyap", "viral", "darshit", "arpit", "sameer", "vanraj" };

PdfDocument pdfDoc = new PdfDocument();

int records = collection.Length;
int perpage = 3;
int pages = (int)Math.Ceiling((double)records / (double)perpage);

int idx = 0;

for (int p = 0; p < pages; p++)
{

    PdfPage pdfPage = new PdfPage();
    pdfPage.Size = PageSize.Letter;
    pdfDoc.Pages.Add(pdfPage);
    XFont NormalFont = new XFont("Helvetica", 10, XFontStyle.Regular);
    using (var pdfGfx = XGraphics.FromPdfPage(pdfPage))
    {
        for (int i = 0,next = 100; i < perpage; i++)
        {
            if ((idx + i) >= records.length) break;
            pdfGfx.DrawString("Name : " + collection[idx  + i].ToString(), NormalFont,
                XBrushes.Black, 55, next, XStringFormats.Default);

            next += 20;
        }
    }

    idx += perpage;

}
