Of all the new features trumpeted for .NET 3.5 SP1 recently the one bullet point that really caught my attention was this little gem (from Brad Adams blog).
A new BindingGroup in System.Windows.Data (additional databinding support)
At this stage I haven’t downloaded and installed the bits. Anyone know what this “BindingGroup” refers to – I haven’t heard/seen it mentioned anywhere else.
[Update 28-May-2008:The WPF Performance blog provides some further hints on the purpose of BindingGroup]Item-Level Validation – By using Binding Groups this applies validation rules to an entire bound item. For example it can enable validate & commit scenario for a form with few bind-able edit fields. (available in final RTM bits only)
