Returns the approximate height of the display, in pixels.
Assembly: System.Web (in System.Web.dll)
The returned value can be derived from the assumed character size and character height. The algorithm for determining the pixel height uses a combination of the default font sizes (from a .config file), device-specific sizes (again, from a .config file), and explicit headers sent by the devices. These values are not necessarily exact. Some devices might rely on internal default values, which only approximate the actual height.
