With this release, you can customize the Detail View's default layout in your Data Model code using the DetailViewLayout attribute. Please refer to the following example code/screenshot below:
public class Contact {
[Browsable(false)]
public int ID { get; private set; }
[DetailViewLayoutAttribute(LayoutColumnPosition.Left)]
public string FirstName { get; set; }
[DetailViewLayoutAttribute(LayoutColumnPosition.Right)]
public string LastName { get; set; }
[DetailViewLayoutAttribute("FullName", 0)]
public string FullName {
get { return FirstName + " " + LastName; }
}
[DetailViewLayoutAttribute(LayoutColumnPosition.Left)]
public string Email { get; set; }
[DetailViewLayoutAttribute(LayoutColumnPosition.Right)]
public virtual Contact Manager { get; set; }
[DetailViewLayoutAttribute(LayoutColumnPosition.Left)]
public DateTime? Birthday { get; set; }
[FieldSize(FieldSizeAttribute.Unlimited)]
[DetailViewLayoutAttribute("NotesAndRemarks", LayoutGroupType.TabbedGroup, 100)]
public string Notes { get; set; }
[FieldSize(FieldSizeAttribute.Unlimited)]
[DetailViewLayoutAttribute("NotesAndRemarks", LayoutGroupType.TabbedGroup, 100)]
public string Remarks { get; set; }
}
Non-Persistent Objects Enhancements
In this release we have extended support for usage scenarios when using non-persistent objects first introduced in v15.1:
- The New, Delete and Save Actions are available for non-persistent objects. Modified objects are accessible using the NonPersistentObjectSpace.ModifiedObjects property.
- The INotifyPropertyChanged.PropertyChanged event is now triggered for non-persistent objects.
- The non-persistent Object Space is now accessible for objects that support IObjectSpaceLink.
- Security permissions are immediately refreshed once the administrator applies changes. You are no longer required to log off all affected users to refresh permissions (learn more...).
- If the administrator grants certain permissions to a reference or collection property that participates in an association (one-to-many or many-to-many), the same permissions are automatically granted for a property at the other end of this association (learn more...).
- The Data View mode in now supported.
- Upcasting is now supported in List View columns.
You should expect more news in this regard after the official release.
General usability and API improvements:
The following is a list of minor features that should make using XAF a little easier. While you can see the full list of these smaller enhancements in our What's New docs, I would like to highlight the following items:
- S38140 - Core - Introduce IObjectSpace.Evaluate method that will evaluate a criteria expression against both EF and XPO objects (including Domain Components)
- Q483608 - Core - Make it easier to obtain IQueryable<T> collection through IObjectSpace for LINQ
- S171061 - Core - Provide an option to avoid saving a master record immediately when a new non-aggregated child object is created in a nested List View
- S170756 - Core - Provide Refresh method overloads allowing the refresh of the underlying data source
- T204296 - EF.Usability - Support complex types that are not registered in DbContext and have no key property
- T177760 - EFDataView - Support common criteria function operators
- S172038 - Core - Provide a simplified database compatibility check mode; one that relies on the database schema and ignores module assembly versions
- T312781 - ImagePropertyEditor - Support images declared as reference properties instead of byte array
- T303205 - Workflow - Add an option to repeat the workflow multiple times while the target object fits criteria
=====================================
I will post additional content on some of these items (like S172038) separatly, once we release v15.2. Please stay tuned and let us know what you think of these new features.
