Inherit from a Web User Control

[Magnus Strandberg]

Hi,

Is it possible to inherit from a web user control (*.ascx) created in a
separate class-assembly to a local specialized control that can be used in
an aspx-page ?
What I want to do is to create some sort of base class library of controls
to inherit from, and use in specific dotnet web apps.
Any ideas ?

User contrls (*.ascx) are sure handy, but they aren't very reusable across
projects.
To create a class library, you should start up Visual Studio and create a
new project of type "class library" of course! This will result in Custom
controls instead of User controls, and they are much more reusable and much
easier to extend.

Yes. You can inherit from the user controls.

I would suggest the following:

1. Create custom user controls without ascx files.
2. Enhance this custom control in the ascx file.

I would rather warn against deriving your class from the dynamically
created user control from the ascx file. DO NOT DO that. It may work
today, but not tomorrow if the strategy of compilation changes.
