Hi Atif,
Thank you for using Syncfusion products.
Sorry. As of now, we don’t have support for the mentioned feature with “Schedule Timeslot Customization and Setting Appearance to the Schedule including Header Color and Timeslot Color” in Xamarin Forms. We have already logged feature report on including these mentioned features, and it will be included in our upcoming volume 3, 2016 release. After this only, the customization support to the Schedule can be provided.
Regards,
Subburaj Pandian V
