See original GitHub issue

.NET Core Version:

.NET Core 5.0.0-alpha.1.19564.1 (also reproduces in earlier versions of .NET Core WinForms.

Have you experienced this same bug with .NET Framework?: Yes

Problem description:

The issue is that RichEdit control is not shown in the UIA hierarchy of PropertyGrid control children.

Expected behavior: RichEdit control (when shown) should appear in the PropertyGrid control’s children hierarchy.

Minimal repro:

Create WinForms app with PropertyGrid and Button control.
Associate the button with PropertyGrid as a selected object.
Run the app, type something in the RichEdit control control (this is a button’s text input control) and inpsect the button with the Inspect tool. Observe that the input is not in the UIA hierarchy.

Thank you for the points @merriemcgaw and @weltkante ! The solution works for all drop-down editors. But popup inner accessibility and accessible hierarchy is the responsibility of editor’s developer.

Verified the issue with latest .NET 6.0.100-preview.1.21080.4 from Release/6.0.1xx-preview1 branch, it is fixed. Now RichEdit control (when shown) appears in the PropertyGrid control’s children hierarchy.
