Hello,

I generate lots of pdf's with different set of data. I have an issue generating a pdf with one set of data. The table get not splitted over multiple page and part of the data is missing.

Moreover with the same set of data I get an error ""Invalid index in Cells indexer: 5" when saving the document. I identified the code part causing the problem when saving :

//Format data table

int nbColumns = table2.Rows[1].Cells.Count;

for (int i = 0; i < nbColumns; i++)

{

   width = table2.GetMaxColumnWidth(pdfDoc, i);

   table2.SetColumnWidth(i, width);

}

PdfDoc.Save(Utils.BuildFilePath(timeSerie, timeSerie.IdDataCategory, Enums.FileFormat.PDF, timeZone, timeSerie.Date, int.MinValue, true));

StackTrace :

"   at Aspose.Pdf.Cells.get_Item(Int32 index)\r\n   at Aspose.Pdf.Xml.ᖂ.ᖌ(Pdf Ӕ, Section Ⴛ, Table Ֆ, Ӟ Ӷ)\r\n   at Aspose.Pdf.Xml.ᖂ.ᖄ(Pdf Ӕ, Section Ⴛ, Table Ֆ, Ӟ Ӷ, Boolean ᎘)\r\n   at Aspose.Pdf.Xml.ᕶ.ᕹ(Pdf Ӕ, Section Ⴑ, Ӟ Ӷ)\r\n   at Aspose.Pdf.Xml.ڇ.႐(Pdf Ӕ)\r\n   at Aspose.Pdf.Xml.ᦈ.ᦍ(ӟ ຬ, Pdf Ӕ)\r\n   at Aspose.Pdf.Pdf.Save(String pdfFile)\r\n   at ETSOVistaLib.PDFGenerator.BuildPDFFile(TimeZoneInformation timeZone, TimeType timeType, MemoryTimeSerie timeSerie, Int32& timeZoneIndex, Boolean buildGroupHeader) in D:\\VSS\\Projects06\\ETSOVista\\Dev\\ETSOVistaLib\\JobOutputGenerators\\OutputGenerators\\PDFGenerator.cs:line 398"

It will be difficult to post the data set used because it's a set of business objects. Could you maybe give me a hint on the error message ? I think in someway my pdftable is corrupt and it would explain both problems. I included the entire pdf generation function enclosed. 

Thanks

Gilles

Dear Gilles,

It is difficult for us to reproduce this error. Can you please provide a runable project that can reproduce this error?

Dear Tommy,

I made a project reproducing the errors. The issue comes from the spanned header cells content. If the content of the spanned cells is too large to fit on one page it will not split over multiple page and cause the following code to throw exception when saving the document if not in commentar :

////!!! THIS BLOCK MAKES PDF.SAVE() THROW EXCEPTION WHEN USED !!!!

int nbColumns = table2.Rows[1].Cells.Count;
for (int i = 0; i < nbColumns - 1; i++)
{
width = table2.GetMaxColumnWidth(pdfDoc, i);
table2.SetColumnWidth(i, width);
}

Please try the project enclosed. I used Aspose.PDF 3.5.8 runtime 2.0

Thank you

Gilles

Dear Gilles,

I have reproduced this error and logged as PDFNET-3787. We will try to fix it soon.

Dear Hans,

Thank you for the patch provided promptly. The patch works with the sample I given to you. I made a try with another content and it doesn't split the file. I just modified the text content of the top merged cells in the new file.

Please try the enclosed test project to reproduce the problem.

Best regards

Gilles

Hi Gilles,

We are working on this issue now. We will try to fix it ASAP.

Best regards.

Hi,

The Table Landscape splitting problem is resolved. Please try the attachment before our new hotfix.

Now, the method GetMaxColumnWidth()    returns the max column's width rather than the cell's it used to.

Thanks for your patience.

Best regards.

Dear Hans,

Thank you for the updated dll, i made some try with it and it works fine. The GetMaxColumnWidth works fine too. I just still have some minor issues on some output documents but I think that I can pass trough by changing document margin and configuration.

Attached you will find two pdfs ("FR-ES-2007" and "FR-BE-2007")

FR-ES problem is that part of the document is still truncaded, FR-BE problem is that on the second page the header is wrapped. Could you give me an advise on how to solve that ?

Thank you very much

Gilles

Dear Gilles,

I can see the problems. I will work on that and give you a solution soon.

Best regards.

Dear Gilles,

For FR-BE problem:
Our design is that when a cell with ColumnSpan > 1 and spans two pages, the cell will be split into two cells. And the content of the original cell will be shown in these two cells both. I think this is necessary, but this also result in one problem as shown in "FR-ES-2007": on the second page the header is wrapped.
To avoid this,You can use following method to set the wrapped header's column width to a proper value before pdf.save().
  Class Table:
  public void SetColumnWidth(int columnNumber, float width);

For FR-ES problem:
I am afraid it is hard to reproduce the error with the project you provided before. Would you please attche the corresponding project? It will help us to resolve the problem. Thanks.

Best regards.
