I've recently worked on several Silverlight projects and did get basic
support from jaws. Textblocks are all read properly in the virtual buffer -
combo boxes and list boxes are all useless. Jamal posted a Silverlight
example on the web.I don't seem to remember but I guess you could look in
the list archives. The apps I was working on were all internal to various
organizations.
As for this app, I don't have the option of changing the textblocks.

Hi Manish,
You have gotten Silverlight to work with JAWS? I have never seen this work,
is there a working example on the web?
As for the textblocks, my advice though not entirely elegant, is to use a
textbox that allows the control to be in the tab order.
Static text has always been problematic in applications, but in the past you
could use the JAWS cursor to roam around the screen. But with
MSAA/UIAutomation JAWS does not seem to build an off screen model, so the
JAWS cursor is not useful. So JAWS reads where the tab order goes.
I suppose if this is not an option, a JAWS script could be tried to have it
access the textblock at the object level and speak it out on demand. I
don't' like screen reader specific fixes (e.g., scripting) unless there is
no other way as it is that much more to maintain and also ties the user to
one screen reader. But you sometimes do not have a choice.

Subject: [program-l] UIA - WPF and textblocks
Hi,
At work, I am working on creating a WPF application , which is almost
completely inaccessible (as expected) out of the box.
There are several textBlocks on the screen that present useful information
to the user but are not a part of the tab order and never get focus.
Jaws does a fairly good job with these in Silverlight where it loads
everything in a virtual buffer. However, with a WPF app, jaws doesn't pick
up anything at all.
Also, UIA exposes a whole lot of information with grids but none of the
screen readers seem to give me even very basic support for content in
tables, let alone full table support.
Combo boxes are announced as "combo boxes" and that is the end of it. I
cannot figure out any way of reading the contents and current selection
inside a combo box.
With NVDA, I am able to get to most of the textblocks and grid cells using
object navigation. Object navigation is however, hardly a good way of
accessing an application as a user and gives very little sense of the layout
of the content on the screen.
I also tried the demo version of the new window eyes 7.5 (it has UIA support
now) and got results comparable to NVDA but because of lack of WE's
capability or my lack of practice with that product (not to mention the very
irritating 30 minute limit before re-boot), I couldn't make much progress.
Has anyone done any work on these problems and made any more progress -
specially with jaws or any other screen reader?
