What if you use composition? Create a new class to contain all your
shared functionality, then in each control class create an instance
variable of that type. That way you don't have to implement the code in
multiple places. Like:
public class MyCommonFunctionality
public sub Method1
end sub
...
end class
Public Class MyLabel
Inherits System.Web.UI.WebControls.Label
private _common as new MyCommonFunctionality
...
_common.Method1
...
end class

Hey all,
I am trying to reuse a bunch of Class members, properties, and
functions
that are shared across multiple classes. Each of these classes
already
inherit form a web control so I can not create a base class supporting
the
function since .Net does not support multiple inheritance. Right now
each
Inherited class has a complete copy of this code that makes it hard to
make
changes to it.
So invision...
MyControl1--\ /---BaseControl1
MyControl2--->Common Code Class<----BaseControl2
MyControl3--/ \---BaseControl3
What I really need is multiple inheritance...
Public Class MyLabel
Inherits System.Web.UI.WebControls.Label)
Inherits MyCommonStuff
End Class
Since so many of these are shared properties and members using basic
interfaces would not really save that much code space. What I was
trying to
do is mix in generics and do something along these lines...
Public Class MyBaseControl(Of t)
Inherits t
Class members...
Functions...
Properties...
End Class
Public Class MyLabel
Inherits MyBaseControl(Of System.Web.UI.WebControls.Label)
End Class
Public Class MyTextbox
Inherits MyBaseControl(Of System.Web.UI.WebControls.Textbox)
End Class
So what I need is to somehow make my intermediate class inherit the
base
control of my choice at runtime based on the type passed through the
generic. Is anything like this possible? I have not had any luck so
far.
Thanks for any help,
Jon
