Assembly	Sets the assembly where the namespace associated with the TagPrefix property resides. The assembly name does not include the file extension. If you place the source code file for the custom control under the App_Code folder of the application, ASP. NET will dynamically compile the source file when running, so you do not have to use the Assembly property
Namespace	To set the namespace of a custom control that is being registered
Src	Relative or absolute location of the declarative user control file associated with Tagprefix:tagname
TagName	Any aliases associated with the class. This property is used only for user controls
