We researched the case and I confirm this is an issue in RadDataGrid with cell decoration style selector.
The problem comes from the fact there are RowBackground/AlternateRowBackground styles defined and at some point the recycling items logic messes up between those and the cell decoration styles.
I updated the status of this item to "Approved" and marked it with high priority, so the dev team will check it soon. Please follow the feedback item in order to receive an email notifications on status changes.
In the meantime, as a workaround, you can remove the RowBackgraoundStyle and AlternateRowBackgroundStyle properties and use only the cell decoration style selector.
I've updated your Telerik points as a small sign of gratitude for reporting this issue. I am sorry for any inconvenience caused.

Hello Mani,
Thank you for attaching the files, I managed to reproduce the described behavior with cell decoration style on iOS.
I would need some more time to research this in more details, I would write back with an update in a day or two at latest.
Thank you for your patience.
