Hi I am using Aspose.word. I need to create a Index page which will have topic heading and total number pages under that topic, Please suggest me how I can do this ??
Hi,
Thanks for your inquiry. In your case, I suggest to use DocumentBuilder.InsertTableOfContents method to create TOC (table of contents). This method inserts a TOC (table of contents) field into the document at the current position. After creating a table of contents, the following field is inserted into the document: { TOC \o “1-3” \h \z \u }.
Please use the following code snippet to create TOC in document.
// Use a blank document
Document doc = new Document();
// Create a document builder to insert content with into document.
DocumentBuilder builder = new DocumentBuilder(doc);
// Insert a table of contents at the beginning of the document.
builder.InsertTableOfContents("\\o \"1-3\" \\h \\z \\u");
// Start the actual document content on the second page.
builder.InsertBreak(BreakType.PageBreak);
// Build a document with complex structure by applying different heading styles thus creating TOC entries.
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");
// Call the method below to update the TOC.
doc.UpdateFields();
doc.Save(MyDir + "AsposeOut.Docx");
You can insert Fields in MS Word document by using DocumentBuilder.InsertField Method. I suggest to read following documentation links for your kind reference.

Please use following code snippet to add NUMPAGES field to show total number pages in document.
Document doc = new Document(MyDir + "in.docx");
DocumentBuilder builder = new DocumentBuilder(doc);
builder.MoveToDocumentEnd();
builder.Write(" Total Page ");
builder.InsertField("NUMPAGES", "");
doc.UpdateFields();
doc.Save(MyDir + "AsposeOut.docx");
