Note Note
Before proceeding, take a moment to review
the following lessons. Before proceeding, please take a moment to review the following courses.
- Place an Action in a Different Location
- Add a Class from the Business Class Library and Use the Scheduler Module (XPO/EF)
- The operation in other locations
- Add Class from Business Class library and use the Scheduler module (XPO / EF)
The New Action's items are defined in the Application Model by child nodes of the CreatableItems node. So, to add an item to the New Action, it is necessary to add a child to the CreatableItems node. By default, business objects whose declarations are decorated by the CreatableItemAttribute or DefaultClassOptionsAttribute can be created via the New Action from any View. However, the Event class (added in the Add a Class from the Business Class Library (XPO) topic) has none of these attributes applied. This class is declared in the Business Class Library. Although it is possible to modify the library sources and recompile the library, it is more convenient to make customizations in the Application Model.
The new entry node operation defined by CreatableItems child node in the application model. So, to add items to "New Action", you must add a child node to CreatableItems. By default, modify its declaration by CreatableItem class properties or default options attribute of the business objects can be created by any of the views of "new operation." However, the event class (added from Business library (XPO) theme add class) do not apply these attributes. Such statements are in business class library. Although you can modify and recompile the source database library, but more convenient to customize the application model.
-
Invoke the Model Editor by double-clicking the Model.DesignedDiffs.xafml file from the MySolution.Module project. In the tree view, navigate to the CreatableItems node. If you expand this node, you will see the items that correspond to the business classes used in your application. These items were generated because the DefaultClassOptions attribute is applied to the corresponding classes. To add another item, right-click the CreatableItems node, and choose Add... | CreatableItem.
