application | XafApplication | An XAF application instance where Object Space Providers are registered. |
Remarks
Follow the steps below to use this method:
- Handle the XafApplication.ObjectSpaceCreated event in a module or Controller.
- In the event handler, call the
PopulateAdditionalObjectSpaces(XafApplication)
method to populate the AdditionalObjectSpaces collection with all necessary Object Spaces.
The following example demonstrates how to do this in a platform-agnostic module (MySolution.Module/Module.cs(vb)):
using DevExpress.ExpressApp;
//...
public class MySolutionModule : ModuleBase {
//...
public override void Setup(XafApplication application) {
base.Setup(application);
application.ObjectSpaceCreated += Application_ObjectSpaceCreated;
}
private void Application_ObjectSpaceCreated(object sender, ObjectSpaceCreatedEventArgs e) {
CompositeObjectSpace compositeObjectSpace = e.ObjectSpace as CompositeObjectSpace;
if (compositeObjectSpace != null) {
if (!(compositeObjectSpace.Owner is CompositeObjectSpace)) {
compositeObjectSpace.PopulateAdditionalObjectSpaces((XafApplication)sender);
}
}
}
}
