This can be found in TabSettings.Width.
Yes but TabSettings.Width = 0
This means that the tab will automatically try to take the necessary space for the caption.
yes but how can I get the width ? I need this value
I'm sorry for this misunderstanding, I didn't get that in your initial post. You can get the Width via the Tab rectangle in the code:
AdvOfficePager.GetTabRect( [PageIndex/Page] ).Width
