Blazor GridCheckboxColumn remains selected even when the row is not a part of selected items


I have a Blazor grid with multiple selection, and the selection is taken care of using the SelectedItemsChanged event. In that event, I want to check if the selected items satisfy certain criteria, and if not, ignore that particular selection change event.

In the attached sample project, if the EmployeeID is not 6, then the SelectedItems property would get updated. If you see the attached screenshot, that seems to almost work. Employee 6 is not highlighted like the other selected items. But the checkbox is still selected, and that would be confusing since the row is actually not a part of the selected items.

The sample project uses version 2.12, but in another project which runs 2.27, it happens there too.

Please let me know if there's something I missed.
