As I understand, Thomas needs a layout in which the header shows something like 

1. Chapter title -- 1.1. Section title (including the numbers! This is the important bit!)

There are a couple things about this: 

1. In a section (part, chapter, section, etc.) you can introduce three versions of the title for that section. title= is the general one and if nothing else is specified, this will be used in markings (headers or footer or wherever you want to put therm) and in listings (contents). If you give those arguments, marking= and listing=, you will get those texts in those places: marking= on markings (you can call them with \getmarking) and listing= in the table of contents. 

2. As far as I have found, including the chapter/section number in the marking is not really a trivial task. I usually hack something using \headnumber and \getmarking, like so: 

\setuppagenumbering[alternative=doublesided,location=,]

\setupheadertexts[{\headnumber[section].~\getmarking[section]}---{\headnumber[chapter].~\getmarking[chapter]}]
\setupfootertexts[][pagenumber][pagenumber][]
\setuphead[chapter][header=high]

\starttext
\dorecurse{10}{
  \startchapter[title={This is my chapter}]
  This is a chapter\par \dorecurse{6}{\input knuth } \input math-kontinuitet-sv

  \startsection[title={This is my section}]
   This is a section\par \dorecurse{6}{\input knuth }\input math-kontinuitet-sv
  \stopsection
  \stopchapter
}
\stoptext

But with a caveat: the `header=high` setting in setuphead for the chapter needs to be included, or you will get a section number in the first page, even if there is no section. I have not found a better mechanism yet, but I'm quite sure there is a correct solution for this... I just haven't found it yet. Checking for the presence of \getmarking[section] with \doifsomething does not work, or I could not make it work.

Rename the section, then you don’t need marking.

Sorry, I'm in a hurry and must look up how to get the number…

Hi Hraban,

and thanks.

setuphead[chapter,section][numberwidth=2em] or "fit"
works!

I know
\setupheadertexts, but do not know what shall I write here:
\startsection[titel=Aufgabe, marking=?????]
If I write marking=Aufgabe I get Aufgabe, no number! For chapter the same.

\setupheadertexts
       [] [{\getmarking[chapter]} - {\getmarking[section]}] [{\getmarking[chapter]} - {\getmarking[section]}] []
----> Kapitel - Aufgabe


Thanks in advance
Greetings
Thomas

HI folks,

yesterday while reading along I learned how to suppress the chapter numbers in sections. That was something I was looking for myself.

But how do you use marking correctly in startsection? I would like to see "1. Kapitel - 1. Aufgabe" in the header on the right. How can I automate this with marking?
And how can I reduce the space between the number (1.) and the title (Kapitel or Aufgabe)?

Thanks for your help
Thomas

Hi Thomas,

do you know how to use \setupheadertexts?

https://wiki.contextgarden.net/Command/setupheadertexts

I guess you're using the section level for "Aufgabe"?

Then something like {\getmarking{chapter} – \getmarking{section}} might fit your request.

The formatting should be possible with \setuphead[chapter,section][numberwidth=2em] or "fit".

Hraban

You want to grab a politician by the scruff of the neck and drag him a quarter of a million miles out and say, ‘Look at that, you son of a bitch.’” — Apollo 14 astronaut Edgar Mitchell
