Hi All,

Before I spend a lot of time reading/testing..

Can anyone tell me if nHibernate support Bi-Directional binding ?

ie. Can I create say an INVOICE object which is bound to a table, then link the INVOICE object to a Winform DataGrid and edit the grid in real time with updates going into the INVOICE object ??

Any info would be much appreciated..

PS.. Wilsons ORMapper only has read binding, not update.

Yes, it is possible to use any IList with objects as a datasource for Winforms controls. Don't expect anything fancy though. To take full advantage of Winforms databinding, you have to implement IBindingList and ITypedList. NHibernate collections don't implement this interface, so there is a little extra work to do.

BTW, this has nothing to do with which O/R mapper you choose. It's purely a matter of binding objects to Winforms controls, so NHibernate and WilsonORMapper are the same in this area.

Is there anyway to get a bindable collection from nhibernate? I've thought about creating my own BindableList which is just inherits ArrayList and implements IBindingList.. but then I was unsure how I could have this list work with nhibernate. Does anybody have working samples on how to bind (I don't care if you are using windows forms binding or something else that is home grown).

I found the hardest part of implementing ITypedList is supporting object refrences.

i.e. Person.Department.Name doesn't work as a binding with the standard dot net classes.
