scenario: update Table of content using OpenXML SDK 2.5

I will be adding contents in between the document using OpenXML/c#. TOC is already present in the document, I just want to update it programmatically. How to do it ?

Thanks in advance :)

What I have tried:

mainPart.DocumentSettingsPart.Settings.Append(new UpdateFieldsOnOpen() { Val = true });

I update existing TOC using this, But when user opens the document, gets a popup(Would you like to update fields this).

How to suppress that ?(I've gone through MSDN links. It seems to be risky) else, is there any alternative like fieldupdate thing to update TOC while generating document?
