Designed public class MyForm : System.Windows.Forms.Form

[Daniel P.]

Since multiple inheritance does not exist in C# I would like to be able to
subclass the Form and then have other class subclass MyForm. If I do that
then the designer will not see my classes as Forms anymore.

How can I fix that and have the design behave as MyFinalClass subclasses the
Form directly?

Thanks!

Daniel,

You should be able to get designer support from the form. Are you
declaring the base form as abstract? The designer doesn't know how to
handle this, since it needs to instantiate an instance of the object in
order to work with it.

Hope this helps.

You are right. It was abstract. Thanks! Now it works.
