Server Mode does not work if you bind the GridControl and DataLayoutControl to the same collection, and use the DataLayoutControl as the grid's Edit Form, because the CurrencyManager does not manageServer Mode Data Sources. All Server Mode data sources except forXPServerCollectionSource are read-only.

This example handles theFocusedRowChanged event to synchronize the DataLayoutControl's data source (XPBindingSource orBindingSource) with the focused row in the GridControl.

1. Bind theDataLayoutControl to a data source in the Visual Studio Designer.

• If your ORM is XPO, add theXPBindingSource component from the toolbox.
  1. Rebuild the project.
  2. Select theXPBindingSource.ObjectClassInfo property in the Properties window, open the drop-down list, and choose an appropriate XPO class.
  3. AssignXPBindingSource to theDataLayoutControl.DataSource property.
• If your ORM is EF or a different library, add theBindingSource component from the toolbox.
  1. Rebuild the project.
  2. Click theProject > Add New Data Source menu item.
  3. Choose the Object Data Source Type and click Next.
  4. Choose an appropriate class in the list and clickFinish.
  5. AssignBindingSource to theDataLayoutControl.DataSource property.

2. Retrieve data fields.
3. Select theGridView and subscribe to theFocusedRowChanged event.
4. Use thee.Row property to obtain a data object that corresponds to the focused row and add it to the data source.

privatevoidGridView_FocusedRowObjectChanged(objectsender,FocusedRowObjectChangedEventArgse){XPBindingSource.DataSource=Session.GetLoadedObjectByKey<ServerSideGridTest>(e.Row);}

PrivateSubGridView_FocusedRowObjectChanged(ByValsenderAsObject,ByValeAsFocusedRowObjectChangedEventArgs)XPBindingSource.DataSource=Session.GetLoadedObjectByKey(OfServerSideGridTest)(e.Row)EndSub

privatevoidGridView_FocusedRowObjectChanged(objectsender,FocusedRowObjectChangedEventArgse){objectobj=DbContext.ServerSideGridTests.Single(e.Row);BindingSource.Clear();BindingSource.Add(obj);}

PrivateSubGridView_FocusedRowObjectChanged(ByValsenderAsObject,ByValeAsFocusedRowObjectChangedEventArgs)DimobjAsObject=DbContext.ServerSideGridTests.Single(e.Row)BindingSource.Clear()BindingSource.Add(obj)EndSub
