Hi Neil,
Thank you for contacting Syncfusion support.
We have checked with your mentioned query, “Resizing of an appointment on mouse over”. In schedule, it is possible to resize an appointment only by selecting the appointment and resizing it through context menu or drag and drop or through Commands. Resizing option couldn’t be enabled on mouse over, only by selecting the appointment it is possible to show the resizing option. As in outlook, we have considered to resize the selected appointment on selection of that appointment itself and without using possible Schedule commands, drag and drop or context menu. Could you please revert us whether this satisfies your requirement? Else could you please provide us more details regarding your requirement?
Also, currently there is no support to modify or customize the resizing icons (two dots).We have logged a feature request for the same and we will implement this feature in any of our upcoming volume release.
Regards,
Swathi G
