Hi Viet,

Plenty of things that was added into toolbox are Custom Controls

User Controls

User controls are authored in the same fashion as a standard Web Form. This makes user controls relatively easy to create, especially when aided by a visual designer such as Visual Studio .NET. Hence, given the same WYSIWYG and declarative environment as an ASP.NET page, user controls can be created with or without a code-behind file, and can handle their own events independent of the parent page. Design-time support for user controls, however, is limited. User controls are represented only by a dull placeholder and properties cannot be set via the Properties window. Also, user controls cannot be added to the Toolbox; sharing of user controls is achieved through placing the necessary user control files in each Web application directory.

Custom Controls

Unlike user controls which are authored in the same fashion as a Web Form, custom controls are compiled and distributed in binary format. Control authors must create their own classes which subclass from System.Web.UI.Control either directly or indirectly by subclassing another control. Custom controls are created without the aid of a designer and require the author to overcome a much steeper learning curve. On the other hand, custom controls provide strong designer-time support. Once compiled, custom controls can be added to the Toolbox and be used the same fashion as the other controls that ship with the .NET SDK such as the TextBox and Button controls. Furthermore, custom controls can expose properties which can easily be set by page developers using the Properties window of the visual designer. Finally, custom controls allow authors to extend or modify the functionality provided by existing controls.

Thanks Najak so much about explanation. I said module in c# or Asp.net because i often hear people talk that "we have to create several module to create a website faster and easily". I think module is a part of website and when we want to use it ,we drag and drop it into the position of website that i want.And i think it like user control .That reason why i ask you about component and module.
This is website i read :http://support.microsoft.com/kb/307996
and http://www.dart-creations.com/joomla/joomla-tutorials/the-difference-between-modules-and-components.html .I hope helped!!Thanks. My purpose is i want to understand clearly so much about module,component and the things that be added into toolbox like Textbox and combobox.I want to create a thing for only me that be added into toolbox.

What is the context of the word "module"? Where do you see that word used? The term has meaning in VB (at least in earlier versions of VB) but I am not aware of the word being used for C# or .Net.
