This article explains the concept of associating the Asp.Net Ajax HoverMenu Control with GridView and to manipulate the records in database with the help of HoverMenu. HoverMenu is an ASP.NET AJAX extender that can be attached to any ASP.NET Server Controls, and will associate that control with a popup panel to display additional content. When the user moves the mouse cursor over the main control, the popup gets displayed at the specified position and a CSS style can also be applied to the main control to highlight the selection or mouse over action. For demonstration, we are going to populate an ASP.NET GridView with data from a database.
