Verified

Expected behavior: Group list should be displayed.

Minimal repro:

  1. Create a Winforms core project
  2. Drag and drop a ListView control to Form designer, open its smart tag and click "Edit Groups"
  3. In ListViewGroup Collection Editor, click "Add" button to add two groups, then click Ok button
  4. Focus on ListView control again, open its smart tag and click "Edit items"
  5. In ListViewItem Collection Editor, click "Add" button to add two items
  6. Select these two items, click the drop-down button of Group property in the right table, observe the drop-down box
