Differences between SelectedRecords and SelectedRowIndexes with infinite scroll

[Julien Barach]

Hi,

Before using infinite scroll on my grids, I used SelectedRecords to know what or how many rows are selected.

When I enable infinite scroll and PersistSelection to true the behavior of the grid is correct but SelectedRecords doesn't update when you check all then scroll down to load more items.

Repro link : https://blazorplayground.syncfusion.com/BDLytqVVLnZAcDIn

1. Check all (25 items loaded and selected)
2. Scroll to load more (the grid show thats 50 items are selected)
3. Click "Show selection" to display differences between SelectedRecords and SelectedRowIndexes

SelectedRowIndexes is correct but not SelectedRecords that stays to 25.
Is it a bug or a feature ?

Regards

Hi Julien Barach,

We are currently validating the reported issue as a high priority on our end and will update you with further details within two days (April 7th, 2025). Until then, we appreciate your patience.

We sincerely apologize for any inconvenience and delay you may have experienced.

We were unable to include the fix in tomorrow’s patch release because we have changed the flow of persisted selection and need more time to ensure the fix is properly validated on our end. However, we want to assure you that the fix will be included in our Volume 1 Service Pack release, scheduled for mid-May 2025. We will update you once the release is rolled out.
