BindingGroup in .NET 3.5 SP1?

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)

  1. I think (only think) that is about canceling the edition of several controls and that all the bindings in the group revert to the previous value (very useful for editing lines in a grid)

  2. I don’t believe BindingGroup shipped as part of the beta, or at least I can’t find it anywhere. It was touched on very briefly at the MVP summit, but I haven’t been able to find any more information about it. Mysterious 🙂
