  • When applied to a business class, specifies the default value of the Application Model's BOModel | <Class> node property.

The ModelDefaultAttribute.PropertyName parameter specifies the property name, and the ModelDefaultAttribute.PropertyValue specifies the string representation of the default value.

using DevExpress.ExpressApp.Model;
// ...
[ModelDefault("Caption", "Task")]
public class DemoTask : Task {
