Hi Umair,
Greetings from Syncfusion Support.
We have validated your requirement “Need to remove the horizontal scroll bar” at our end but we regret to let you know that we can ‘t remove the horizontal scroll bar. Because we have positioned the date header and the content area by the horizontal scroll. If we remove the scroll bar, the appointments are not positioned at the exact position. Please refer to the below sample.
Regards,
Vengatesh
