Hi Ros,
We have prepared a sample that could address your requirement 'Preventing Looping in SfDateTimeCombo'. In the sample we have modified the combobox ItemsPanel to stackpanel which restricts the item's lopping effect.
Please find the sample in below link,
Please let us know if the sample meets your requirement. If your requirement is different please provide us more information on query, so that it will be helpful for us to provide you accurate solution.
Please let us know if you have any queries.
Regards,
Vignesh V
