Thanks for your interest in Syncfusion products.
Regarding Custom Appointment Editor
We have analysed your query, as “department” is not field available in the ScheduleAppointment of our SfSchedule control, we are not able to add this field to our default AppointmentEditor by customizing its template. In order to handle custom class properties like “department”, we need to use the custom AppointmentEditor instead of the default AppointmentEditor. For that please refer the below sample,
Dashboard -> WPF - > Schedule -> Customization Demo
Regarding creating Schedule control (instead of SfSchedule control)
As SfSchedule is newer version, we have removed Schedule icon from the toolbox and add SfSchedule icon in it.
In order to add Schedule control to you project please refer the below procedures,
#1. Create a new WPF Application project in Visual Studio.
#2. Right click on the project and Choose Syncfusion Reference Manager
#3. Select Schedule from it (refer the attached screen shot) and click “ok”.
#4. Add the XAML reference to access the schedule related controls as below.
#5. Declare the Schedule control in XAML as illustrated below.
<schedule:Schedule x:Name="Schedule" />
Please let us know, if you need any further assistance.
