I'll take Common.Case1

[dkazennov]

Regarding Common.Case1:

ListViewItem components of the ListView control have accessible objects. Debug and accessible tools show that these accessible objects are being created.

But the main issue is: accessible tools do not fix checking the checkboxes of ListViewItems. The Narrator doesn't announces checks. ListViewItem can contain checkbox, but it doesn't behave like CheckBox control.

I have changed the ListViewItemBaseAccessibleObject: added announcement by Narrator the same way as in TreeView

[Tanya-Solyanik]

Only a single task is fixed so far.

Verified this issue in the latest .Net 8.0 SDK build:8.0.100-alpha.1.22478.15, Details-Case 2 was fixed. The image already has its accessibility object in the ListView. please check below screenshot:

Is it makes sense to add ListViewItemImageAccessibleObject to ListViewItem in List, Tile, SmallIcon, LagreIcon styles? In these styles, we haven't SubItems, and currently, the tree looks neat:

List1

ListViewItem1 ListViewItem2 ListViewItem3

But in my opinion, if we will rework it like Details style it looks cumbersome (especially for ListViewItem without Image):

List1

ListViewItem1

ListViewSubItem1

ListViewItem2

ListViewImage ListViewSubItem1

ListViewItem3

ListViewSubItem1

In all of these styles, a ListViewItem cannot contain more than one SubItem. @merriemcgaw what do you think if we add child AccessibleObject only for Image like a Subtitle (see image below)?

[merriemcgaw]

It sounds reasonable to me but also want @Tanya-Solyanik's input here too.

[Tanya-Solyanik]

@NikitaSemenovAkvelon - I did not understand your suggestion. you are saying that this:

List1

ListViewItem1

ListViewSubItem1`

adds hierarchy where none is needed, right? But what is the alternative? No subitem?

ListView1

ListViewItem2

ListViewItemImage

And a different question - is it possible to set accessible name on this image?

[NikitaSemenovAkvelon]

@Tanya-Solyanik exactly. ListViewItemAccessibleObject will have only children like an image or subtitle without subItem. I attached the image above with an example of how it works now with subtitles. Item1 has a subtitle, subsequently, it has a child AO, but Item2 hasn't a subtitle therefore it is without any children.

And a different question - is it possible to set accessible name on this image?

I don't see any easy way to set it without adding a new property to ListViewItem which will be used in the AO.

[Tanya-Solyanik]

I don't see any easy way to set it without adding a new property to ListViewItem which will be used in the AO.

This is a problem. There is no point in announcing "ListVIewItem2, image" because the user would not know what that image is. It's valuable to have image node in the hierarchy only when that image had text associated with it. But let's wait until this issue is raised by external users.

I think hierarchy with no mandatory subitems is reasonable.

[NikitaSemenovAkvelon]

Tested the remaining cases which are still unchecked.

• Details.Case 1. OK

• Details.Case 3. OK

• Tile.Case 2. OK

I suggest marking these cases as completed.

[NikitaSemenovAkvelon]

@merriemcgaw I think, we can close the issue, doesn't it?

[MandiMan]

Verified on latest 8.0 build .NET 8.0.100-alpha.1.22607.6, a part of the issue was fixed. User can see information about image via accessibility tools in LargeIcon, SmallIcon and List views. please check below screenshot: LargeIcon view: SmallIcon view: List view:
