I currently have some XAML defined like this:
... ItemsSource="{Binding BomHeaders, NotifyOnSourceUpdated=True}">
AND this _vm = new ViewModels.BomHeaderVM();
AND thisthis.DataContext = _vm;
If I retrieve some data like this BomHeaders = new ObservableCollection<Model.BoMHeader>(dal.GetBomHeader()); my data access layer return a list of entity framework POCO's.
My UI datagrid refreshes accordingly and I can add,remove objects.
My Question is if I clear my observable collection
and use a button to retrieve an entire new observable collection again like this
BomHeaders = new ObservableCollection<Model.BoMHeader>(dal.GetBomHeader());
How do I get the itemssource to refresh when I basically recreate the observable collection?
If I raise a PropertyChange event and in the event do this
BindingOperations.GetBindingExpressionBase(this.test, DevExpress.Xpf.Grid.GridControl.ItemsSourceProperty).UpdateTarget();The data is refreshed.
Is this the only way to do this?
Or is there some better way to do this declaratively in XAML?
Thanks
