• validation server controls
  A set of server controls, included with ASP.NET, that verify user input. The input is checked as it comes from HTML server controls and Web server controls (for example, a Web page form) against programmer-defined requirements. Validation controls perform input checking in server code. If the user is working with a browser that supports DHTML, the validation controls can also perform validation using client script. See also ASP.NET server control, HTML server control, Web server control.
• validator
  See definition for validation server controls.
• value type
  A data type that is represented by the type's actual value. If a value type is assigned to a variable, that variable is given a fresh copy of the value. (This is in contrast to a reference type, where assignment does not create a copy.) Value types are usually created on a method's stack frame, rather than in the garbage-collected heap. A value type can be boxed, which is a process that creates a corresponding reference type. See also: boxing, reference type, unboxing.
• verification
  A part of the compilation process in which code is checked for conformance to a specific set of rules defined to allow proof of certain security requirements. The common language runtime can verify Microsoft intermediate language (MSIL). See also: Microsoft intermediate language (MSIL).
• version policy
  The rules that specify which version of dependent assemblies to bind to. Version polices are expressed using configuration files.
• view state
  The current property settings of an ASP.NET page and those of any ASP.NET server controls contained within the page. ASP.NET can detect when a form is requested for the first time versus when the form is posted (sent to the server), which allows you to program accordingly. See also: ASP.NET page, ASP.NET server control.
