Author: admin | Posted: 30-05-2010 | Category: ASP.NET(vb.net) & Web User Control

ASP.NET(vb.net) & Web User Control - Web User Control : Web user controls are controls that you can define as you need them for your applications, using the same programming techniques that you use to write Web Forms pages. You can create Web user controls when you need to create reusable pieces of UI that will be used throughout your application. A user control can contain HTML, server controls, and event-handling logic. Like a compiled control, it can expose properties that the host Web Forms page can set.
