This feature was first
demonstrated in our v14.2 release and based on your feedback, was one of the most
popular additions to the eXpressApp Framework. For this release, we have made it even more
powerful by implementing the following features:
- The latest design-time changes made by developers to
the Model.XAFML file representing shared model settings will be automatically
re-read and considered by the application while debugging in Visual Studio.
Technically, we have integrated a code solution from
this Support Center thread under the #DEBUG directive via the XAF solution
wizard so that all newly created apps have this default behavior. If you need
this feature in your existing app, implement the current solution from the
aforementioned thread.
- As for updating shared model settings in production
environments, you can now import the new settings from the application UI via
the Import Shared Model Difference Action of ModelDifferenceViewController,
which is available in WinForms apps only. Technically, this command silently
loads the contents of the Model.xafml file to the Shared Model
Difference object stored in the database.
- Initially, there was no easy way to have application UI
settings for WinForms and WebForms apps stored in the database separately. With
the v15.1 release, the ModelDifferenceDbStore class constructor was
extended to accept the string ContextId parameter. This allows you to pass
“Win”, “Web” and other custom constants, like “Tablet”, for different
applications and configure their user settings independently. To save you time, the default
prefixes are automatically added for new applications by the XAF solution
wizard. Existing applications can be modified as follows:
private void Application_CreateCustomUserModelDifferenceStore(Object sender, CreateCustomModelDifferenceStoreEventArgs e) {
e.Store = new ModelDifferenceDbStore((XafApplication)sender, typeof(ModelDifference), false, "Web");
e.Handled = true;
}
The code of the Create Model Differences Action of
ModelDifferenceViewController was modified to take into account all the
available ContextId values and create Model Difference objects in the database
for each available application user.
- Previously, the Copy Model Difference Action opened
a dialog to copy model settings for the selected user to another user by fully
overriding them. With our current release, you can choose to
either Overwrite target model differences or Merge the
source and the target using the Copy Behavior option:
Technically, this is a smarter version of the
Copy command that does not replace everything, but rather combines both
differences together. At this stage, there are no special dialogs to merge only
certain Application Model setting nodes as is done in the Merge
Model Tool.
