Content going over a PdfGrid

[Luke Bennett]

Hi,

Currently I have a PdfGrid that is created that gets data from a 2D string array. The string array is filled using data from a data grid view which my users can enter data into. Currently if I enter lots of information into the data grid view, then the table goes over to the next page fine, but then the data that needs to get placed underneath it ends up on top of the grid on the top of my PDF. Below is what I currently have drawing the grid and getting its height for the next object:

Code: Select all

result = itemGrid.Draw(page, new PointF(0, y));
y = y + result.Bounds.Height + 10;


But the height is now the height of the one row that made its way onto the second page. What I need to know is how to tell my next few elements whether or not the result has ended up onto the next page, and then how to draw my next objects below it.

I also have another problem where if the grid is only just on one page, then my content is getting draw behind my footer. My header and footer is created using the PdfPageTemplateElement, but for some reason instead of my next content going onto the next page it is just getting draw behind the footer template.

Any help would be appreciated, thanks.

Hello,

Thanks for your inquiry.
1.After you draw the Grid, you could get pages. Then draw your next objects according to the page number.
Here is the code for your reference.

Code: Select all

 PdfLayoutResult result= grid.Draw(page, new PointF(10, y));
            y = y + result.Bounds.Height + 10;
            PdfTrueTypeFont font1 = new PdfTrueTypeFont(new Font("Arial", 10f));
            int count = doc.Pages.Count;
            PdfPageBase page1 = doc.Pages[count- 1];
            page1.Canvas.DrawString("hello world",font1,PdfBrushes.Red,10,y);   

2. I recommend you to judge the position before you draw the content.
Here is the code for your reference.

Code: Select all

  namespace pdfTest
{
    public partial class Form1 : Form
    {   
       public static float TemplateTopHeight, TemplateBottomHeight;

         private void button3_Click(object sender, EventArgs e)
        {   //...
              SetDocumentTemplate(doc, PdfPageSize.A4, margin);   
               PdfPageBase page = doc.Pages.Add();
               PdfGrid grid = new PdfGrid();
            float y = 70;
            grid.Columns.Add(2);
            for (int i = 0; i < 11; i++)
            {
                PdfGridRow row = grid.Rows.Add();
                row.Height = 51f;
            }
            PdfLayoutResult result = grid.Draw(page, new PointF(10, y));
            //int count = doc.Pages.Count;
            //page = doc.Pages[count - 1];
            string label = "hello world";         
            PdfTrueTypeFont font1 = new PdfTrueTypeFont(new Font("Arial", 10f));
            y = y + result.Bounds.Height + 10;
            float height = font1.MeasureString(label).Height;
            float bottom = doc.PageSettings.Size.Height - doc.PageSettings.Margins.Top - doc.PageSettings.Margins.Bottom - height - TemplateTopHeight - TemplateBottomHeight;
            if (y > bottom)
            {
                page = doc.Pages.Add();

                page.Canvas.DrawString(label, font1, PdfBrushes.Red, 10, y - bottom);
            }         
            else
            {
                page.Canvas.DrawString(label, font1, PdfBrushes.Red, 10, y);
            }
           
        }
          static void SetDocumentTemplate(PdfDocument doc, SizeF pageSize, PdfMargins margin)
        {
          //...
           TemplateTopHeight = topSpace.Bounds.Bottom;
           TemplateBottomHeight = bottomSpace.Bounds.Bottom;
         // ...
             

         }   
   


     }
}

Hi Sweety, thanks for the reply.

The first section is perfect, can't believe I didn't think of that before...

And for the second bit, what is this line:

Code: Select all

 float bottom = doc.PageSettings.Size.Height - doc.PageSettings.Margins.Top - doc.PageSettings.Margins.Bottom - height - TemplateTopHeight - TemplateBottomHeight;

going to calculate? Won't the margin top & margin bottom also be apart of the template top & bottom heights?

Hello,

Thanks for your reply.
Yes, this code going to calculate the position. The margin top & margin bottom also be apart of the template top & bottom heights.

Okay thanks.

I've implemented getting the page using the count, but whenever I draw anything on to the second page, I get the error "An error exists on this page. Acrobat may not display the page correctly. Please contact the person who created the PDF document to correct the problem." and the page no longer has any margins or a header/footer.

If I remove my DrawStrings and just let the grid go over to page two then the header and footer and all the margins are shown correctly, it only breaks when I begin to add more elements to the page.

Any ideas why this would happen?

Thanks,
Luke

Hi,

Attached is my shelled out solution with 3 PDFs. The solution needs the free Spire.PDF 3.2 version re-adding via Nuget as with it the size was above the maximum upload.

The first one is my PDF that doesn’t spread over 2 pages, which is working fine.
The second one creates the PDF to the point of the grid which shows that my template is working fine on the second page before I add any other content.
The third PDF has an error when I open the second page, and loses the header and footer. This only happens once that extra bottom section of the PDF is generated.

Hopefully this will help you diagnose the problem.
