Hi ,

I am new to Aspose.Word .

I have created a Table of content in my word document but their headings are not properly aligned. I have attached my word document for reference.
My code:

using (Stream fileIO = System.IO.File.Open(Server.MapPath(filePath), FileMode.Open, FileAccess.Read))
{
    Aspose.Words.Document doc = new Aspose.Words.Document(fileIO);
    Aspose.Words.DocumentBuilder builder = new Aspose.Words.DocumentBuilder(doc);

    builder.InsertTableOfContents("\o "1 - 3" \h \z \u");
    builder.InsertBreak(BreakType.ParagraphBreak);

    builder.ParagraphFormat.StyleIdentifier = StyleIdentifier.Heading1;
    builder.Writeln("Heading 1");

    builder.ParagraphFormat.StyleIdentifier = StyleIdentifier.Heading2;
    builder.Writeln("Heading 1.1");
    builder.Writeln("Heading 1.2");
    builder.ParagraphFormat.StyleIdentifier = StyleIdentifier.Heading1;
    builder.Writeln("Heading 2");
    builder.Writeln("Heading 3");
    builder.ParagraphFormat.StyleIdentifier = StyleIdentifier.Heading2;
    builder.Writeln("Heading 3.1");
    builder.ParagraphFormat.StyleIdentifier = StyleIdentifier.Heading3;
    builder.Writeln("Heading 3.1.1");
    builder.Writeln("Heading 3.1.2");
    builder.Writeln("Heading 3.1.3");
    builder.ParagraphFormat.StyleIdentifier = StyleIdentifier.Heading2;
    builder.Writeln("Heading 3.2");
    builder.Writeln("Heading 3.3");
    doc.UpdateFields();
    doc.UpdatePageLayout();
    doc.Save("c:\x.doc");
}

Hi Tahir,

I am using Aspose.word.dll version 16.8.0.
I missed my first line in the code .I am reading from a Template file and then appending the table of content in it.If I don’t pass fileIO object in the document class I am getting the result with headers properly aligned.But If I pass the fileIO stream to the Document class my headers get wrongly aligned.I have attached my Template file for your reference.

In my Template file I have 3 text starting with @@Table which I am replacing by table,image and attachment.Along with that I need to have a TableofContent also.

Please suggest if I need to make any changes in the template file for achieving my scenario.

My code starts with:

string filePath = ConfigurationManager.AppSettings["Templatefile"].ToString();

if (!string.IsNullOrEmpty(filePath))
{
    using (Stream fileIO = System.IO.File.Open(Server.MapPath(filePath), FileMode.Open, FileAccess.Read))
    {
        Aspose.Words.Document doc = new Aspose.Words.Document(fileIO);
        Aspose.Words.DocumentBuilder builder = new Aspose.Words.DocumentBuilder(doc);

Hi Joydev,

Thanks for your patience. Our product team has completed the analysis of your issue and the root cause has been identified. The Normal style of the Template.docx document has left indention 3 cm. The document has no TOC1 style, since it has no a table of contents. Aspose.Words imports all necessary styles (TOCx) from embedded document in library. So, after importing the TOC1 style into the destination document, its left indention becomes 3 cm as in the Normal style.

Please set the LeftIndent of TOC1 style to 0 as shown in following highlighted code. Hope this helps you. Please confirm if this solves your issue.

Aspose.Words.Document doc = new Aspose.Words.Document(MyDir + "Template.docx");
Aspose.Words.DocumentBuilder builder = new Aspose.Words.DocumentBuilder(doc);
builder.Writeln();
builder.MoveToDocumentStart();
Field field = builder.InsertTableOfContents("\\o \"1-3\" \\h \\z \\u");
field.Start.ParentParagraph.ParagraphFormat.LeftIndent = 0;
builder.InsertBreak(BreakType.ParagraphBreak);
builder.ParagraphFormat.StyleIdentifier = StyleIdentifier.Heading1;
builder.Writeln("Heading 1");
builder.ParagraphFormat.StyleIdentifier = StyleIdentifier.Heading2;
builder.Writeln("Heading 1.1");
builder.Writeln("Heading 1.2");
builder.ParagraphFormat.StyleIdentifier = StyleIdentifier.Heading1;
builder.Writeln("Heading 2");
builder.Writeln("Heading 3");
builder.ParagraphFormat.StyleIdentifier = StyleIdentifier.Heading2;
builder.Writeln("Heading 3.1");
builder.ParagraphFormat.StyleIdentifier = StyleIdentifier.Heading3;
builder.Writeln("Heading 3.1.1");
builder.Writeln("Heading 3.1.2");
builder.Writeln("Heading 3.1.3");
builder.ParagraphFormat.StyleIdentifier = StyleIdentifier.Heading2;
builder.Writeln("Heading 3.2");
builder.Writeln("Heading 3.3");
doc.Styles[StyleIdentifier.Toc1].ParagraphFormat.LeftIndent = 0;
doc.UpdateFields();
doc.UpdatePageLayout();
doc.Save(MyDir + "Out v17.1.0.docx");
