Custom Appointment Dialog Form Values Not Set

[Joe]

Hello,

I have a custom appointment class and a custom appointment edit template.  I am using validation.

During the validation I would like to modify some of the dialog form values.  I do see the property set in the custom appointment/validation class, however the custom dialog form does not show the changes.  I have set the binding mode to twoWay.

<ControlTemplate x:Key="EditAppointmentTemplate" TargetType="telerik:SchedulerDialog">

Hi Craig,

In RadScheduleView by design the appointments properties do not notify the UI while the EditAppointmentDialog is opened.

You can refer this code library that shows how to create a ViewModel with properties that will be updated while the EditAppointmentDialog is opened.
