The Asp.net Ajax control toolkit has a lot of very good controls, but the one that seems to be sorely lacking is a Asp.net Ajax Data Grid. The one control I use the the most is the datagrid. While I realize that you can wrap the GridView in an update panel and you can purchase a third party control, I don't understand while Microsoft just doesn't come out with its own version. Preferably one that does not require custom code to page without pulling the entire dataset. I would think that most developers would welcome a Asp.net Ajax Data Grid that comes as a built in Microsoft control. Please consider it.
