I am using aspx forms. What we do is that we declare property like for every form. Code is at the end
So I was thinking that if we could have a base class that have all the stuff like this but as the form already inherit the Page class we don't have multiple inheritance in C# so here can we use interface to achieve this I am new to oops please let me know it is possible or not.
public partial class Default2 : System.Web.UI.Page
{
public string ImagePath { get; set; }
}

06-Dec-2014You don't need to inherit from two classes. You need to create a class layer in-between.
First create a class that inherits from Page and add your property:
Then inherit all other classes from your base class. In there you can access everything from Page and MyPageBase:

06-Dec-2014You have two options.
Create a base class
You can create a base class that inherits System.Web.UI.Page and inherit this class in all your pages:
And then inherit this class in your pages:
Create an interface
You can create an interface like this:
And then inherit this interface on all your pages:
As you can see, the first option (base class) has some advantages over the interface option. You have to define and implement your property only once when using a base class. When using interfaces you have to implement the property on every page too.
This is because an interface is only used to define what properties and function there are on an object, not how they work. While a base class can already implement the properties and functions.
