Gridview control features, properties,events and style properties in asp.net

The GridView control is a powerful data grid control that allows you to display an entire collection of data, add sorting and paging, and perform inline editing. In addition to just displaying data, the GridView can be used to edit, select and delete the displayed data as well.

The GridView control supports the following features:-
 1. Improved data source binding capabilities
 2. Tabular rendering – displays data as a table
 3. Item as row
 4.Built-in sorting capability
 5. Built-in select, edit and delete capabilities
 6. Built-in paging capability
 7. Built-in row selection capability
 8. Multiple key fields
 9. Programmatic access to the GridView object model to dynamically set properties, handle events and so    on
10. Richer design-time capabilities
11.Control over Alternate item, Header, Footer, Colors, font, borders, and so on.
12. Slow performance as compared to Repeater and DataList control
