The DevExpress MVC Scheduler allows you to easily substitute default dialogs with custom forms tailored to suit your requirements. This demo illustrates how to invoke a custom appointment editing form and to display a custom inline editing form.
Double-click an appointment for inline editing form. Right-click an appointment and select Open to show a custom appointment editing form. Note that this form allows you to edit custom appointment properties obtained via custom mappings (Price and Contact Information).
The SchedulerSettings.OptionsForms property allows access to the MVCxSchedulerOptionsForms object which provides you with methods such as the SetAppointmentFormTemplateContent and the SetAppointmentInplaceEditorFormTemplateContent. You can implement partial views which represent custom forms, render and pass them to these methods.
