Remarks

The GetValue<T> method is in effect only for DevExpress editor extensions (i.e. EditorExtension class descendants).

Use the static GetValue<T> method to access the editor value within the controller code.

Note

In order to pass the editor value to the controller, place the editor within the <form> tag (e.g. using the Html.BeginForm Method) and then submit the form to the server.

Note that the client-side validation of user input can prevent the form from being submitted it to server unless the end-user input is valid.
