Getting Started

In VS.NET you just create a Web Custom Control Library and you're set.

In Notepad, you will need to create a normal .vb file and add the following -

Imports System.Web.UI

Namespace AGASP

Public Class Ctrl1
Inherits System.Web.UI.WebControls.WebControl

..code goes here...
End Class

End Namespace

You can see that we are Inheriting the System.Web.UI.WebControls.WebControl class, we could Inherit the Control class, but this one already does inherit Control and provides some additional methods, properties etc.

Title: Custom vs. User control BLUNDER – user control CAN be referenced in the code.

Implementing page can reference user control exactly the same way as custom control, otherwise there is really little use for them. And Yes, it does not create user control variable when you drag and drop it on the page, contrary to custom control. So leave your mouse alone and strike the damn keyboard and enjoy user controls in the code behind.
