Thanks Teddy:
It looks like an investment site. Can't find any CheckBoxes on any TreeViews
though., Checked the Source as well.
Guess I'll have to build one if I want something really nice.
There are a couple of examples but I'm not sure about the StateImage they use.
My inspiration comes from the VWD or Vb.net Menu>Tools>Options window. On
this menu the TreeView will read "Partially Checked" when a Parent Node's
Children are mixed, checked and unchecked.
That means there is an Icon, or some StateImage or Image, that a Screen Reader
will recognize as a Partially Checked CheckBox and a CheckState, or something
that will correspond to that image. Actually, there are 3 states, Checked,
UnChecked and Indeterminate for some flavor of a .net CheckBox. Whether that
can be applied to asp.net is another question I'm starting to dig into.
I need to find the various enumerations for the images, or indexes in the
appropriate image list, the number or whatever else might identify the grayed
CheckBox image and hhow to apply the image to my Treeview's Node ChehckBoxes in
conjunction with the appropriate CheckState. So I may have to build a TreeView
inheriting stuff, never wanted to get that detailed programming, but it is what
it is.
Thanks again and i'll be back with more questions after I get a grasp on the
various pieces. Something about win32 versus .net is popping up when Googling
Custom Controls and TreeViews and CheckBoxes so I still have to do allot of
reading about it all and creating Custom Controls, sigh.

Hi,
Yes I've seen a kind of Javascript tree view, something very stupid in my
opinion, but it is very accessible for the blind.
That site is made in .net, so it would be possible to create it in VS.net.

Hi Guys:
Looking for a Tri-State TreeView control it seems commercial ones are
expensive and the code to build one complicated to say the least.
Before I waste a ton of time and gray matter trying to build one, has
anyone used one that works with a Screen Reader?
Anyone have some code that worked floating around?
If not I'll try and build one but it sounds complicated and I don't know if
the resultant tri-state checkbox would even be readable with a Screen Reader so
might just waste a ton of time.
Let me know if you've used a Tri-State TreeView, html JavaScript or asp.net
version, either third party, open source or one you built yourself so I know
if this might be doable somehow.
