Updating an object value in a grid

[Fredo]

I have a DataTable and in one of the columns, I'm storing an object. When
certain properties of that object change, I want the DataTable to trigger an
update in the grid (via the CurrencyManager).

Is that possible without setting the Row/Col to a new instance of the
object?

Here's the thing: I want to keep the object independent of the DataTable
itself. I'd also like to, for example, be able to use it in a collection
bound to a grid. I'd also like this to all happen from within the object
itself, if possible. This is an object we're actually creating for other
developers to use and I basically want to give it the ability to trigger a
CurrencyManager update when certain properties are changed.

Hi,

You need to implement INotifyPropertyChanged interface on your object. This
will notify all the databound controls to this object to change accordingly.

Hope this helps

For completeness, as soon as you start talking about grids it can get more
complex: you may also need to implement IBindingList (for e..g ListChanged
events and SupportsChangeNotification) and IRaiseItemChangedEvent {just
return true from RaisesItemChangedEvents}.

Of course, implementing IBindingList is a black art in itself... google has
some useful hints (it helped me; sadly my scanario is too complex to post),
but you could also (in 2.0) see if BindingList<Thelps at all?
