Multiple columns for table of content

Aspose.PDF Product Family

I tried to set the ColumnInfo.ColumnCount property to 2 for a ListSection of type “Table of Contents” and it doesn’t seem to work. Is there a way to list the table of contents in multiple columns?

thanks.

Hi,

I’ve attached the sample PDF file, can you please take a look over it and confirm if it is the desired behavior that you have been looking for. I’ve created it using the following code snippet and Aspose.Pdf 3.9.0.0

[C#]

Pdf pdf = new Pdf();
Aspose.Pdf.Section sec1 = pdf.Sections.Add();
sec1.ColumnInfo.ColumnCount = 2;

for (int Level = 1; Level <= 61; Level++)
{
    Heading heading2 = new Heading(pdf, sec1, Level);
    Segment segment2 = new Segment(heading2);
    heading2.Segments.Add(segment2);
    segment2.Content = "Item Number " + Level.ToString() + "...................." + Level.ToString();

    // Add the heading into Table Of Contents.
    heading2.IsInList = true;
    sec1.Paragraphs.Add(heading2);
}

pdf.Save(@"d:\pdftest\ColumnInfo_test.pdf");

Hi,

Please try the beta version that is attached and code as below. We will publish a new official version in about 3 weeks, it will be reliable than the beta version .

Thanks.

[C#]

Pdf pdf = new Pdf();
Section sec = pdf.Sections.Add();
Heading heading = new Heading(pdf, sec, 1);
Segment segment = new Segment(heading);
heading.Segments.Add(segment);
heading.TextInfo.Alignment = AlignmentType.Center;
segment.Content = "Title";
sec.Paragraphs.Add(heading);
//Create the Table Of Contents. Add it to the pdf like a common Section.
ListSection tocSection = new ListSection(pdf);
tocSection.IsNewPage = false;
tocSection.ListType = ListType.TableOfContents;

tocSection.ColumnInfo.ColumnCount = 2; // when I enable this property, TOC is displayed in 2 columns but is messed up.

tocSection.ColumnInfo.ColumnWidths = "5cm 5cm"; // Even setting the value to "50% 50% " didn't worked
tocSection.ColumnInfo.ColumnSpacing = "10";
pdf.Sections.Add(tocSection);

//Define the format of the four levels' list.
tocSection.ListFormatArray.Length = 62;

Aspose.Pdf.Section sec1 = pdf.Sections.Add();
for (int Level = 1; Level != 62; Level++)
{
Heading heading2 = new Heading(pdf, sec1, Level);
Segment segment2 = new Segment(heading2);
heading2.Segments.Add(segment2);

// heading2.IsAutoSequence = true;
segment2.Content = "Heading - ";
segment2.Content += Level.ToString();
//Add the heading into Table Of Contents.
heading2.IsInList = true;
sec1.Paragraphs.Add(heading2);
}


pdf.Save(@"d:\TOCnew.pdf");
