Why doesn DataSourceUpdateMode.OnPropertyChanged work for ADO.NET data sources?
When binding to ADO.NET tables using simple list binding, the Windows Forms runtime binds to an instance of an ADO.NET DataRowView. The DataRowView supports row level commit semantics via an interface called IEditableObject (see the IEditableObject section for more information). IEditableObject requires changes to be “committed” prior to the changes being accepted by the data model. When binding to the DataRowView, the DataRowView will update as a result of data binding however it defers change notification until the row has been committed. What this means is that even though the DataRowView has been updated, other controls are not aware of the update and therefore don’t show the updated value. You can work around this by either manually forcing other bound controls to refresh their contents or by explicitly calling EndEdit on the DataRowView. Sample: Explicitly calling EndEdit with simple binding (VS 2005) (VS Project: OnPropertyChangedBinding) In VS 2005, a new event named BindingCom
