RavenDB Workshops - Deep dive into practical use of Document Data Modeling

Apr 25 2006

I don't think that data binding likes me

time to read 2 min | 353 words

Why I don't like data binding:

You can't work with interfaces. If my object has a property with a type IList<T>, it wouldn't work. That is even if the collection implements IBindingList.
An error in the data bound grid cannot be exited short of killing the process.
You can't bind to non-IList data.
It looks like some weird stuff is going on behind the scenes, I get index not found exception when using the data grids, and I'm pretty sure that I am handling everything just fine.
I can't make deleting works, no matter what I do, it looks like the instances that it uses are different than the ones that I'm passing it, but I don't have the time to find out right now. I can get it done more easily if I will simply do it by hand, I am afraid.

I started to add Support for Data Binding to NHibernate Generics:

Added IBindingList, IRaiseItemChangedEvents, ICancelAddNew support for EntityList<T>.
It will automatically subscribe to any inserted item when it implements INotifyPropertyChanged
Support searching out of the box.

Unfortunately, it looks like my implementation is flawed, so I'm not going to commit the changes (maybe to a branch), unless there is anyone out there who know more than I do about data binding and can help me get it to work.

kpvleeuwen, I agree, unfortunately I don't have anyone to ask off the top of my head. Thanks, I fixed the headers.
