Rendering list of grids in PDF

[Chris Adams]

Hi,

I'm trying to render a PDF file with the following structure

CATEGORY TEXT

SUB-CATEGORY TEXT

GRID

GRID

.....

GRID

GRID

SUB-CATEGORY TEXT

GRID

GRID

.....

GRID

GRID

CATEGORY TEXT

SUB-CATEGORY TEXT

GRID

GRID

.....

GRID

GRID

SUB-CATEGORY TEXT

GRID

I have the following code, but it renders grid data on top of each other on the second page. 

PdfGraphics graphics = page.Graphics;

//header on the first page only

float currentYPosition = 55;

//Set the properties to paginate the text.

PdfLayoutFormat layoutFormat = new PdfLayoutFormat();

layoutFormat.Break = PdfLayoutBreakType.FitPage;

layoutFormat.Layout = PdfLayoutType.Paginate;

foreach (var category in categories)

{

    RectangleF categoryBounds = new RectangleF(0, currentYPosition, page.Graphics.ClientSize.Width, page.Graphics.ClientSize.Height);

    //Draw the text element with the properties and formats set.

    graphics.DrawString(category.Name, categoryFont, categoryBrush, categoryBounds, formatLeft);

    currentYPosition += 30;

    foreach (var subCategory in subCategories)

    {

        RectangleF subCategoryBounds = new RectangleF(0, currentYPosition, page.Graphics.ClientSize.Width, page.Graphics.ClientSize.Height);

        graphics.DrawString(subCategory.Name, subCategoryFont, subCategoryBrush, subCategoryBounds, formatLeft);

        currentYPosition += 40;

        foreach (var question in questions)

        {

            //Create PdfGrid

            PdfGrid grid = new PdfGrid();

            //GRID RENDERING LOGIC HERE

            //Set properties to paginate the grid.

            PdfGridLayoutFormat gridLayoutFormat = new PdfGridLayoutFormat();

            gridLayoutFormat.Break = PdfLayoutBreakType.FitElement;

            gridLayoutFormat.Layout = PdfLayoutType.Paginate;

            // Draw PdfGrid

            var gridDrawResult = grid.Draw(page, new PointF(0, currentYPosition), gridLayoutFormat);

            currentYPosition = currentYPosition + gridDrawResult.Bounds.Height + 20;

        }

    }

}

The Essential PDF supports maintaining the position of a PDF grid drawn on a PDF page using PdfGridLayoutResult. It provides the rendered bounds of the previously added grid, which can be used to place successive elements without overlapping. Add multiple PDF grids using the bottom position of the previously rendered PDF grid.

We suspect that the reported issue may occur when the grid is drawn on the incorrect page.

Please add the below code snippet to draw a grid with the layout result of the previous grid:

//Draw the grid on the PDF document page and store the grid position in PdfGridLayoutResult.

PdfGridLayoutResult pdfGridLayoutResult = pdfGrid.Draw(page, new PointF(10, 10));

pdfGridLayoutResult = pdfGrid.Draw(pdfGridLayoutResult.Page, new PointF(10, pdfGridLayoutResult.Bounds.Bottom + 20));
