To bind a DevExpress editor to a value, use the editor's EditorExtension.Bind method. It has two overloads, allowing you to bind an editor either directly to its value or to a specific property of a data object (Model).
When DevExpress editors are bound to data model fields (by using Bind(dataObject, propertyName) methods or using strongly typed helpers), the DevExpressEditorsBinder model binder must be used instead of the default model binder to correctly transfer values from DevExpress editors back to corresponding data model fields.
You can specify DevExpressEditorsBinder as a model binder in the following manners.
Decorating the Parameter of Action Method
You can declare DevExpressEditorsBinder as a parameter attribute on an action method: ([ModelBinder(typeof(DevExpressEditorsBinder))])
