I am kinda new to CSLA, so...the following can as well be put into the "Silly/Stupid" question category.

How do I define an interface using csla ?

Using a base class would solve the problem, but I wanted to see how I can declare and inherit from an interface while using clsa?

Thanks in advance,

You define and implement interfaces in your Csla based objects just as you would normally.

Sometimes its helpful to have your interface specify that one of the Csla interfaces be implemented as well.

For example:

public interface MyInterface : Csla.Core.IEditableBusinessObject {
// interace members
}

Then anything which implements MyInterface must also implement IEditableBusinessObject. Normally that would be the case, because your BO would subclass BusinessBase.

Hi,

A response to a quite old question, however this was the only post I could find.

Inheriting from the core interface was not really the issue, however it results in some methods that might not want to be exposed:

DeleteChild;
SetParent.

Any thoughts on what is the best way to handle this?

Best regards,

Peter

Hi,

Other than to look for maybe another interface higher in the hierarchy then no.

You _can_ implement the methods explicitly so that they are only available when you use the interface (cast) but once it is defined in the interface the methods/properties have to be implemented and available.
