Invalid index in Rows indexer: 0

Aspose.PDF Product Family

Hi All,

I am using Aspose.Pdf dll to generate PDF document.I am getting the issue that “Invalid index in Rows indexer: 0” while generating the PDF.

Where I am getting Issue/Error:
There is a table with many number of rows while generating PDF. Its a for loop to add each row with data in table. Here I am using fontsize 11 to display the text in each row table. The issue is getting here that “Invalid index in Rows indexer: 0” randomly. But not frequently. If I reduce the font size to some 5 number down, then its working without any issue. some code snippet is pasting here. I hope you all understood the issue.

row = pdfTableResourceTeam.Rows.Add();
Cell cellRole = row.Cells.Add();
Text textRole = new Text(teamMemberTable.Rows[count][“Role”].ToString());
Aspose.Pdf.TextInfo txtinfoRole = textRole.TextInfo.Clone() as Aspose.Pdf.TextInfo;
txtinfoRole.FontSize = 8;
txtinfoRole.Color = col;
textRole.TextInfo = txtinfoRole;
cellRole.Paragraphs.Add(textRole);


Any fix for this? Any solution for this defect?

Please help me.

Thanks and Regards
Prathap Reddy

Hello Prathap,


Thanks for using our products.

In order for us to replicate this problem, we need to know the number of rows that you are trying to add to the table and the length/contents being placed inside table cells. If possible, can you please share some sample application which can help us in testing this scenario at our end. We are really sorry for your inconvenience.

Hi Nayyer Shahbaz,

Thanks for your reply.

The number of rows are 15. It may increase or decrease based on data.
The content in the cell is simple text. The text does not contain number of line. Its just name of person.
Font size is 11.

Not possible to share the code. The sample snippet is already placed in my first post. Check the same.

If I change the font then its working. Its generating PDF file. But I don’t want to change the font size. All text in PDF should be in the same font size. that is 11.

Any help?

Thanks and Regards
Prathap

Hello Prathap,


Thanks for sharing the details.

I have tried reproducing the issue while using following code snippet but I am unable to notice the problem. I have tested the scenario using Aspose.Pdf for .NET 6.9.0 and PDF file is properly being generated. For your reference, I have also attached the resultant PDF that I have generated. Can you please help us in replicating this problem . We are really sorry for this inconvenience.

[C#]
// instantiate PDF object
Aspose.Pdf.Generator.Pdf pdf = new Aspose.Pdf.Generator.Pdf();
// create section obejct and add it to pdf document
Aspose.Pdf.Generator.Section section = pdf.Sections.Add();
Aspose.Pdf.Generator.Table pdfTableResourceTeam = new Aspose.Pdf.Generator.Table();
// set the column width information for table cells
pdfTableResourceTeam.ColumnWidths = “50”;
// set the border style for table object
pdfTableResourceTeam.Border = new Aspose.Pdf.Generator.BorderInfo((int)BorderSide.All,0.3f);
pdfTableResourceTeam.DefaultCellBorder = new Aspose.Pdf.Generator.BorderInfo((int)BorderSide.All, 0.3f);
// add the table to paragraphs collection of section
section.Paragraphs.Add(pdfTableResourceTeam);
for (int i = 0; i < 15; i++)
{
Aspose.Pdf.Generator.Row row = pdfTableResourceTeam.Rows.Add();
Cell cellRole = row.Cells.Add();
Text textRole = new Text(“Role-text”);
Aspose.Pdf.Generator.TextInfo txtinfoRole = new Aspose.Pdf.Generator.TextInfo();
txtinfoRole.FontSize =11;
txtinfoRole.Color = new Aspose.Pdf.Generator.Color(“Blue”);
textRole.TextInfo = txtinfoRole;
cellRole.Paragraphs.Add(textRole);
}
// save the reusltant Pdf file
pdf.Save(@“D:\pdftest\Sample_table.pdf”);

Hi Nayyer Shahbaz,

Thank you for your time and information.

Even I am getting the issue randomly but not always. My PDF file is having different sections with large data. I am not sure whether this issue will get for small PDF file generation.

I am using Aspose.Pdf dll version is 5.0.1.0. Is this issue because of using old version dll which may have this bug. Any idea on this? Meanwhile I will download latest Aspose.Pdf.dll and will test my issue. I will update you on this.

Thanks and Regards
Prathap

Hi,


This has been driving me crazy so I took the time to put together a sample project for you. The project is VB.NET 3.5 and I’m using Aspose.PDF version 7.0. This is the same as our production environment.

I ran this sample on Windows 7 64 bit and our server os is Windows Server 2008 / 64 bit

If you select “smallest” and click the Print button, you will get a link to view the pdf.
If you select “largest” and click the Print button, you will get the error message.

The error received is:
System.ArgumentException: Invalid index in Rows indexer: 0 at Aspose.Pdf.Generator.Rows.get_Item(Int32 index) at ..(Pdf doc, Section currentPart, HeaderFooter hf, Table table,  assignInfo,  bakAssignInfo,  useType, Boolean isFirst, & breakTableNextPart) at ..(Pdf doc, Section currentPart, HeaderFooter hf, Table table,  assignInfo,  useType, Boolean isFirst, & breakTableNextPart) at ..(Pdf , Section ,  ) at .†.(Pdf ) at .Ž.( , Pdf ) at Aspose.Pdf.Generator.Pdf.Save(String pdfFile) at AsposeError._Default.btnPrint_Clicked(Object sender, EventArgs e) in C:\Users\Jonathan\Documents\Visual Studio 2010\Projects\AsposeError\AsposeError\Default.aspx.vb:line 26


The layout uses a table with 1 row and 2 cells. I believe the problem has something to do with the content in the left cell going over to the second page.

Please let me know if there is anything that can be done to correct this or if you need any more information from me.

Is there any way for me to keep up with the status of that issue or is that something that is only tracked internally? This issue affects us daily as people continue to get errors when trying to generate their profile. Any information would be greatly appreciated.
