What are user controls and custom controls?
By admin on Jan 8, 2007 in ASP.NET Interview Questions, Technical
Custom controls: A control authored by a user or a third-party software vendor that does not belong to the .NET Framework class library. This is a generic term that includes user controls. A custom server control is used in Web Forms (ASP. NET pages). A custom client control is used in Windows Forms applications.
User Controls: In ASP. NET: A user-authored server control that enables an ASP.NET page to be re-used as a server control. An ASP. NET user control is authored declaratively and persisted as a text file with an .ascx extension. The ASP.NET page framework compiles a user control on the fly to a class that derives from the System.Web.UI.UserControl class.
