>I have a project I did years ago in ASP.NET 2.0 where I used DataGrid control. No problem; it still works very well.

>Now I am working on a new project, in ASP.NET 4.0. I am looking at the Toolbox ->Data controls. Is GridView equivalent to DataGrid I used in 2.0? Do you recommend a different (not 3P) grid view control to use in ASP.NET 4.0?

"Both the DataGrid and GridView controls are derived from the WebControl class. Although it has a similar object model to that of the DataGrid control, the GridView control also has a number of new features and advantages over the DataGrid control, which include:
Richer design-time capabilities.
Improved data source binding capabilities.
Automatic handling of sorting, paging, updates, and deletes.
Additional column types and design-time column operations.
A Customized pager user interface (UI) with the PagerTemplate property."
