Pdf Keep Rows together

[Matt Tracey]

Hi,

I'm creating a pdf and adding a PdfGrid. In the PDF grid I need to keep certain rows together on the same
page. So if the, say, 2 rows didn't fit at the end of a page they would be printed on the next page.

I have previously used PDFSharp which had a "KeepWith" property on a table row to specify blocks that 

must be kept together. I can't find a similar keepwith property and was wondering is there one?

I've attached a project that prints a PdfGrid - in it there are two rows ( row part 1, row part 2) that need to be kept on
the same page. If "row part 1" is at the bottom of a page and "row part 2" is going to be printed on the next page,
then "row part 1" and "row part 2" both need to be printed on the next page.

Thanks in advance,

Matt

Hi Matt,  

Thank you for using Syncfusion products, 

We do not have support for Keeping multiple set of PdfGrid rows together in a page, but we can fit individual element (PdfGrid rows) within a page with the help of code snippet below: 

            //Setting Layout format for the PdfGrid 

            PdfGridLayoutFormat format = new PdfGridLayoutFormat(); 

            format.Break = PdfLayoutBreakType.FitElement; 

 

            //Draws grid to the page of PDF document with speified format. 

            pdfGrid.Draw(page, new PointF(10, 10), format); 

Please find the screenshot for the moved Grid row element to the next page in case if there is lack of space for drawing the next row: 

 

Please let us know if you need any further information regarding this.

Hi,

I was unable to use FitElement to get it working - I had 2+ rows to keep together.

What I ended up doing was adding just one row to the datatable for each of the "rows" I had and using "\r\n" to put the next virtual "row"

on a new line:

Example:

     string lcCol0 = "Row 1 Col 1 Text";

     string lcCol1 = "Row 1 Col 2 Text";

     lcCol0 += "\r\n" + "Row 2 Col 1 Text";

     lcCol1 += "\r\n" + "Row 2 Col 2 Text";

     lcCol0 += "\r\n" + "Row 3 Col 1 Text";

     lcCol1 += "\r\n" + "Row 3 Col 2 Text";

     DataTable loTableData = new DataTable();

     loTableData.Columns.Add("Col1");

     loTableData.Columns.Add("Col2");

     loTableData.Rows.Add(new string[] { lcCol0, lcCol1 } );

Then for the Grid I used a BeginCellLayout:

     PdfGrid moGrid = new PdfGrid();

     moGrid.DataSource = loTableData;

     moGrid.BeginCellLayout += moGrid_BeginCellLayout;

The benefit of this was I was able to bold certain strings within the text using BeginCellLayout and PdfHTMLTextElement,

It also allowed me to draw a border at the top and using BeginCellLayout I had to fudge the border - It was too close to the top.

Below is my BeginCellLayout for my specific need, I only needed to do it for col 6:

private static PdfFont moFont10 = new PdfTrueTypeFont(new Font("Calibri", 10), true);

public static void moGrid_BeginCellLayout(object sender, PdfGridBeginCellLayoutEventArgs args)

{

            PdfHTMLTextElement textElement = new PdfHTMLTextElement();

            textElement.Font = moFont10;

            if (args.CellIndex == 6)

            {

                if (args.Value != "Event category, Consequence and event description")

                {

                    float lnX = args.Bounds.X;

                    float lnY = args.Bounds.Y;

                    float lnL = args.Bounds.Left;

                    float lnT = args.Bounds.Top;

                    float lnW = args.Bounds.Width;

                    float lnH = args.Bounds.Bottom;

                    args.Skip = true;

                    textElement.HTMLText = args.Value;

                    args.Graphics.DrawRectangle(PdfPens.Black, lnL, lnT + 1, lnW, 0);

                    textElement.Draw(args.Graphics, new RectangleF(lnX, lnY+4, lnW, lnH + 4));

                    

                }

            }

}

There was one little gotcha in the BeginCellLayout when I moved the textElement down by "4" the end of the text
moved down as well, so in the Col6 in the datatable I had to append "\r\n" + "\r\n" at the end of a text.

Anyway - It works and the plus is it allows me to use HTML formatting in the text.

Thanks again for your help - just leaving this update in case anyone needs a similar solution.

Cheers,

Matt

BTW - just an addendum:

I also used the FitElement that was suggested before and this made sure the rows stayed on new pages if the
rows are too big.
