DataGridRows not accessible in Release mode

[DanielGlick]

Describe the bug

DataGridRows are not able to be recognized when running UITests when the app is deployed in release mode. This is a problem for me because I need to run the app in release mode to make sure I test closest to what the customer will be getting in my app.

Steps to Reproduce

Steps to reproduce the behavior:

1. Run the attached project in Release mode
   ReleaseDataGrid.zip
2. Open the Inspect

tool or Windows accessibility insights
3. Hover over the first column and first row
BUG 1

4. Click the first row in the first column
   BUG 2

This can also be done by deploying the app in release, then running the uitest located in UnitTest1 in the UITests project in debug.
NOTE: You must have Windows Application Driver running for the uitest to run

Expected behavior

1. It should highlight that control and tell me that it is a DataGridRow or something like that
2. It highlights the data item but in the tree it is not where I expect it to be. It should be in

If you run the uitest it will fail because it could not find the row

Any update on this?

[DanielGlick]

@michael-hawker Can I get an update on this?

[anawishnoff]

@RBrid Any ideas on this bug?

[RBrid]

No idea unfortunately. I ran the Windows Community Toolkit Sample App and Windows' Narrator. Narrator just says "selected" or "non-selected" when navigating to a row, even though we have a DataGridRowAutomationPeer class. A deep dive would be needed to get to the bottom of this.

@RBrid @anawishnoff this might be a regression? As it appears some work was done in the past for this, see #2233. I dug up commits for these changes and commented here.

[DanielGlick]

@RBrid any update on this? This is pretty important to us to get done so we can finish our UWP ui testing in the datagrid.

@DanielGlick45 Régis works on the WinUI team who manage the DataGrid, but they're heads down with WinUI3. If you have some cycles and could test out anything related to the information I dug-up above, that'd be much appreciated.

If you do discover any of the code can be tweaked to resolve the issue, please open a PR and we can get this into our 6.1 release in May.

[anawishnoff]

@DanielGlick45 are you still facing this issue?

[Kyaa-dost]

@DanielGlick45 please let us know if you are still having any issues with this and if not we can close the issue.

[michael-hawker]

@RBrid I noticed you made a comment in your PR to this issue, is this issue now resolved or is there a bit more work here to be done?

[RBrid]

@michael-hawker, let's close this issue. I could not detect any behavior difference between Release and Debug, and Narrator now says "Row Selected" / "Row unselected". All the automation peers seem to be used as expected.
