list.IsRestartAtEachSection does not work with .odt

I create a document with several sections. Each section contains numbered lists. They should begin with 1 in each section. I set list.IsRestartAtEachSection = true. For docx, dotx, doc,… this works, for odt unfortunately not. Is there a way to reset the numbering for each section even when outputting as odt?


To ensure a timely and accurate response, please attach the following resources here for testing:

  • Your input document.
  • Please attach the output ODT file that shows the undesired behavior.
  • Please attach the expected output ODT file that shows the desired behavior.
  • Please create a standalone console application ( source code without compilation errors ) that helps us to reproduce your problem on our end and attach it here for testing.

Hi tahir.manzoor,

the attached application (8.3 KB) creates a document with a list and saves it in various types.

The numbering in docx, doc, dot and rtf starts correctly at 1 after each section change, but continues in dotx, docm, dotm, odt and ott.

Can you reproduce the described behaviour?

The code is an extension of the example in It also points out that only docx, dot and rtf are supported. But how can this be implemented for other types?

In our real application we have a dot template. We clone it, edit it with Replace and insert an rtf file with the list in one place. Then we add the clone in a new section to the existing document. We then save the document as dotx and open it with Process.Start(). The user can then decide whether and where to save the document.


In this case, you need to clone the list or create new list and set it to paragraphs in your desired section.

Is there a way to prevent contained lists from merging when inserting a second document into the first? How would you proceed here?

I think I found a solution:

This code does not work with dotx, odt,…:

Document attachDoc = (Document)templateDoc.Clone(true);
ImportFormatOptions importOptions = new ImportFormatOptions()
{ KeepSourceNumbering = true };
builder.InsertDocument(attachDoc, ImportFormatMode.KeepSourceFormatting, importOptions);

But it is:

Document attachDoc = (Document)templateDoc.Clone(true);
ImportFormatOptions importOptions = new ImportFormatOptions()
{ KeepSourceNumbering = true };
templateDoc.AppendDocument(attachDoc, ImportFormatMode.KeepSourceFormatting, importOptions);
