I have added some ModelProperty instances to the AttachedPropertiesService related to the ModelItem and it's EditingContext. The issue I'm having is that any change to the value of these attached properties do not get reflected in the designer (via
bindings). The only way to get the property grid to display the updated values is to lose focus and then select the activity again. This only provides a display of the current values in the property grid and is still not reflected in the designer bindings.
The other issue I have is that I want to use many of these attached properties as designer data but do not want them displayed in the property grid. Setting them to IsBrowsable = false means that I can no longer find them in the ModelItem.Properties collection.
How do I get changes from the ModelItem properties to update the designer view?
