You are viewing documentation for the legacy WPF Scheduler control. If you’re starting a new project, we strongly recommend that you use a new control declared in the DevExpress.Xpf.Scheduling namespace. If you decide to upgrade an existing project in order to switch to the updated scheduler control, see the Migration Guidelines document.

Set the FormCustomizationUsingMVVM property to true to activate a new MVVM-based mechanism for form display, which allows you to substitute the default appointment editing forms with the custom ones. This property allows you to utilize this mechanism throughout your application for all SchedulerControl instances. For an example on how to substitute the standard appointment editing form with a custom one using the MVVM architectural pattern, refer to the Lesson 7 - Create a Custom Edit Appointment Form Using the MVVM Pattern (legacy) document.

You can also use the form display events of the SchedulerControl to replace the default appointment editing forms. To do this, set the FormCustomizationUsingMVVM property to false and handle the appropriate event depending on the form you want to customize. This approach is described in the Lesson 9 - Create a Custom Edit Appointment Form (legacy) article.
