Hi Akshay,

User controls
User controls are encapsulations of sections of pages which are registered and used as controls in ASP.NET. User controls are created as ASCX markup files. These files usually contain static (X)HTML markup, as well as markup defining server-side Web controls. These are the locations where the developer can place the required static and dynamic content. A user control is compiled when its containing page is requested and is stored in memory for subsequent requests. User controls have their own events which are handled during the life of ASP.NET requests. An event bubbling mechanism provides the ability to pass an event fired by a user control up to its containing page. Unlike an ASP.NET page, a user control cannot be requested independently; one of its containing pages is requested instead.
Custom controls
Programmers can also build custom controls for ASP.NET applications. Unlike user controls, these controls do not have an ASCX markup file, having all their code compiled into a dynamic link library (DLL) file. Such custom controls can be used across multiple Web applications and Visual Studio projects.

Perhaps I misunderstand what you mean by "store" or "stored" in a library.

A UserControl can be in a .Net Class Library. Try it; it is easy to do.

Hi Akshay,

User Control cannot be stored in a library

You can reuse User control in the current project in which you have built it, but you can't move it to other project as unless you just copy paste the same file there and make the changes for that project.

But custom control can be shared between projects. and you can precompile them even as a dll, so this means you can use them in library of any type.

Thanks
