Hello group,
I developed some Domain classes , which are NOT a not related to DataSet /
DataTable etc. in any way. But they provide similar featurs.

A object can for instance contain a collection of Orders, plus a collection
of OrderItems. The collection of Orders contains Orders. Each Order has a
property OrderItems, which returns a collections of OrderItems. This
collection only contains the OrderItems blonging to the corresponding Order
(one to many relation)

From code data binding works perfectly. I can write:

dataGridOrders.DataSource = m_Orders; // instance of Orders Collection
dataGridItems.DataSource = m_Orders;
dataGridItems.DataMember = "OrderItems"; // name of property of Orders class

Thus I can  display master/detail relations very easily, just as if I had
used a DataSet with two tables and a relation object.

Now my Question: I would like to specify DataSource and DataMember in the
Properties Windows of the DataGrid in VS designer, just like I can do with a
typed DataSet. I made my class implement IComponent, thus I can set the
DataSource. But what do I have to implement in my class to be able to
specify the DataMember in designer????
I searched MSDN and the internet for two days now, but could not find any
information on how to do this.
