Simple scheduling control

I want to build a simple scheduling system. Something that would have rooms down the side and dates across the top. The control would show if the room was available.

Is there a control in the toolbox that will do this? Or other open source control that can be downloaded? Or is this something that I should look at doing in a datagrid?

Just looking for some quick advice to get me looking in the right direction.

Thanks, John
