Hello,

Just wanted some clarification on an assumption I've made around "OnPropertyChanged". I can see in the WPF docs that if you pass an empty string to "OnPropertyChanged" it should indicate that all properties have changed - https://docs.microsoft.com/en-us/dotnet ... .0#remarks. Is that the case within Noesis and if not is it possible to do this from a view model?

Thanks!

Just took a look at "BindingExpression::OnNotifyPropertyChanged" and it looks like it doesn't work this way. Would still be good to get confirmation though!

Hi,

This is something we don't have implemented in Noesis, but we should because it could have performance benefits in some situations, as with a single notification all the bindings to the object will be updated. Could you please report it in our bugtracker, we want to support this.

Thanks.

Added the following issue #2432 to the bugtracker to implement this.
