As per the Wikipedia,
ASP.NET is an open-source server-side web application framework designed for web development to produce dynamic web pages developed by Microsoft to allow programmers to build dynamic web sites, applications and services
ASP.NET provides a lot of out of the box control for developing web application; one of them is GrdiView which is used for displaying tabular data. Grandview provides a lot of customization features. In this article, I will show you how to change the GridView header text at runtime.
