A client grid control is probably the most requested control for the Ajax Control Toolkit. It will come eventually but if you need a simple grid control right now, DotNetSlackers’ Ajax Data Controls do a pretty good job. Their grid supports pagination, sorting, drag and drop of columns, in-place edition and is server-integrated. They also provide repeater types of controls but those are made a little more complex to use because of the lack of data binding. The whole thing is open-source. w00t!
