I'm not sure how to improve the things, I don't have strong skills in widgets development. Perhaps while it isn't in navigation order and group position is ignored on it or while it is treated differently then it's ok. Perhaps the problem word I used doesn't describe things well. Just pointing out suspect things. Alexander. On Tue, Nov 9, 2010 at 6:14 AM, Todd Kloots <kloots@yahoo-inc.com> wrote: > I see.

Column headers aren't part of the actual paged data set, so I didn't think that they should have position and setsize defined. Do you know what I mean? Any guidance on how to improve the example would be appreciated. > > - Todd > > On Nov 8, 2010, at 1:40 PM, Alexander Surkov wrote: > >> Hi, Todd. >> >> I think the problem is screen readers just don't support group >> position on row accessibles.

What version of Firefox supports aria-setsize and aria-posinset on rows? I'm testing using FF 3.6.12 using both NVDA 2010.2 and JAWS 12 and don't hear the row positions announced according to the positions I have defined. Could that be due to the screen readers not yet supporting the group position that you are exposing? Here is a like to my test example if you would like to take a look to see if there is anything I am doing wrong. >>> >>> http://public.yahoo.com/kloots/aria/grid.html >>> >>> - Todd >>> >>> On Nov 8, 2010, at 4:01 AM, Alexander Surkov wrote: >>> >>>> Hi, Todd.

The use case would be using a datagrid to present paged data and only the current page is present in the DOM. In such cases you would want to communicate the ordinal position of a row relative to the current page and total number of pages and rows. >>>>> >>>>> Any insight would be appreciated. >>>>> >>>>> Thanks, >>>>> Todd Kloots >>>>> Accessibility Engineer >>>>> Yahoo!, Inc. >>>>> >>> >>> > >
