I have implemented custom data entity objects, so I like to bind my
entities to web server data controls, so I want to know what extra code
I should implement to to do that?

Hi,

You need to derive your objects from System.ComponentModel.BindingList<C>
(is using .NET 2.0) to implement 2 way data binding mechanism.

Vivek

Hi again,

You need to implement IBindingList methods in your custom classes. See this
link for details:

Note: binding changed significantly between 1.1 and 2.0. With 1.1, binding
was only one way. You had to re-wire your properties in order to save values
on postback. 2.0 can do 2 way binding, but requries that your object use
a specific pattern of retrieval/creation and persistance, otherwise you are
stuck with manual binding. If you use the prescribed pattern you can achieve
binding with no custom code. Otherwise, you can code it all yourself.
