using List<object> as a datasource, how??

[Jeff]

..NET 2.0

I'm wondering if it is possible set the DataGridView.DataSource to a
List<objectcollection. Where object is a class derived from the object
class.

If it's possible then my question is how?

I ask becasue I think it's much better to use the collection directly than
performing a foreach statement adding the rows to the DataGridView...

any suggestions?

Suggestion: BindingList<T>

Any list (IList (*)) can be used as a data source, even plain
ArrayList. The binding works much better if the collection implements
a typed indexer "T this[int]", which List<Tdoes (**) - this allows
it to ask for the properties of the type, via TypeDescriptor. And
better again if it supports the binding interfaces like IBindingList,
IBindingListView - hence BindingList<Tis your best bet (as per
Fred's post).

Just some background.

[* aside: or something that exposes a list via IListSource]
[** aside: ITypedList performs a similar role to a typed indexer, but
is more complex to implement]
