Binding to a Coarse Grained Object

#1

I have an object called Invoice which has as one of its members, an object
called customer which is of type Customer. Class Customer has properties
such as CustomerId, CustomerName, etc. In my form, InvoiceDetailForm, I
bind the controls on the form to a binding source InvoiceBS which is tied to
the Invoice object. How do I bind a control on the form to
Invoice.Customer.CustomerId using the designer?

Add a CustomerId Property to Invoice that returns Customer.CustomerId.

So for every field in customer that I need to access and in other classes
that are composites I need to set properties up in Invoice?

I believe so. I don't think you can bind to anything except
properties of the object.

This is a very bad solution. You can easily refer to child objects in a BindingSource
(see solution elsewhere in this thread)

Hi Bill,

Just refer to the property like you would in code.

Invoice invoice = new Invoice();
BindingSource source = new BindingSource(invoice, "");

// Bind to the CustomerName property of the CustomerName object in the Invoice object
textBox1.DataBindings.Add("Text", source, "Customer.CustomerName");

So can this be done only in code or can it be done in the designer property
window for the target object?

Well, partly. It you set Invoice as a DataSource, you should see Customer as a node under Invoice creating the DataBinding in the designer. You won't see any members of Customer, but you can edit the binding in thedesigner and add ".CustomerName". I much prefer doing this in code though.
