The main grid is rendered via XNA, based on the samples on the Creators Club website:

And the grid itself is drawn using code based on the Primitives sample:

I’ve just got a bit of additional state-handling code in there to handle interactions with the thumbnail control, toolbar buttons etc.

So it’s possible to set the level to any size, and use scrollbars or a custom camera to move around the map.

interesting stuff – what control did you use for placing the items on the main grid? I imagine it wouldn’t be too hard to modify that so that you could build up a collection of those grids, and then use XNA to scroll over that map?

Kind regards
