Change Navigation Properties as ObservableCollection<T>

Post by figueiredorj » Tue 28 Jul 2015 09:00

Hi,

Is there anyone that has successfully changed navigation properties to be ObservableCollection<T>?
I am doing MvvM and I need to trigger the RaisePropertyChanged and for current DbContext I have failed on doing this.

Any help appretiated.

Hi,
just replied you by email with a demo project referring the unexpected behavior of the ObservableListSource<T>.

Thanks

Hi,

thanks for the update on implemented feature of Use ObservableCollection<T>;

I was able to use it once.. and noticed that when using that I had to customize template for having the usiong collections;

Besides that..
When it was released I had tested it...
However I am creating a new model with dbcontext but unable to find the feature of using observablecollection; is there something I need to do before? Thanks

Ignore my previous comment when related to not finding where to specify to use ObservableCollection<T>... it is shown by default on dbcontext.. just was using older version on current machine.

Yet it is missing on template to add using for Collections...

Cheers!

If we understood you correctly, the issue was resolved.

JIC: to be able to use ObservableCollection<T> you need to open your *.edml model, navigate to Tools > Entity Developer > Model Explorer > expand the Templates node and set the Use ObservableCollection property of the DbContext template to True; save the model to regenerate the code.

If you have any further questions, feel free to contact us.
