DynamicObject databinding on DataGridView, System.Dynamic namespace

Question

I have some collections of objects that inherits DynamicObject class, all works great with the BindingSource and BindingNavigator, but I don't have the dynamic properties displayed on the DatagridView.

The objects inherits DynamicObject and overrides the TrySetMember, TryGetMethod and GetDynamicMemberNames, I think that it is sufficient.

It also implements the INotifyPropertyChanged interface for the binding updates.

I'm forgetting something? or is it possible to do?

what I have now is:

protected BindingList<Users> _Users;
_Users = _Ctl.GetAll();

BndSrc.DataSource = _Users;

BndNav.BindingSource = BndSrc;

Grid.DataSource = BndSrc;

Note: the _Ctl is a object that gives me all the users, the Users class inherits DynamicObject and have properties defined dynamically, like Username, Password and Name, it is all working well, but the datagrid don't display the dynamic properties.

Your post title and tags indicate this is a C# question - but your sample is in VB.NET? — vcsjones

Sorry my mistake, I work a lot with the 2 languages, but the question is valid for both. — Pedro Simões

I'm confused - this is WinForms DataGridView, not WPF DataGrid? If so, why do you say you implemented INotifyPropertyChanged? — Chris Ballard

Databinding to dynamic (DynamicObject) objects is broken and MS has resolved it as "Wont fix".
