Remarks

• When applied to a business class or a Domain Component interface, specifies the default value of the Application Model’s BOModel | <Class> node property.
• When applied to a business class’ or a Domain Component interface’s member, specifies the default value of the Application Model’s BOModel | <Class> | OwnMembers | <Member> node property.

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

C#

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

VB.NET

Imports DevExpress.ExpressApp.Model
' ...
<ModelDefault("Caption", "Task")> _
Public Class DemoTask
    Inherits Task
    ' ...
End Class

The code above specifies that the Caption property of the BOModel | DemoTask node is set to “Task”, by default. If you customize this value in the Model Editor and later reset this customization, the value will be “Task” again.
