Question

I’m trying to use a Model with my Asp.net page. But im not using MVC. I get an error when trying to inherit the model from a customcontrol. The error is

ViewModel: interface name expected.

public partial class CustomControl : UserControl, ViewModel

Answer 1

You cant do multiple inheritance in C#. UserControl and ViewModel are both classes and you are only able to inherit from a single class.

You can however implement as many interfaces as you like.
