I have a DataGrid in a Silverlight project, fed by an ObservableCollection, and I'd like to have in one column an entry for each row that is either a particular graphic (same graphic for each item), or none. I could use a similar-sized all-white graphic instead if that would be easier than a blank.

Searching on the internet I've found discussions of feeding graphics to the DataGrid from a SQL database and other similarly complex operations, but that's all far, far more complexity than I'm aiming for. I'd only need the one (or two) small graphic files, and each cell in that column of the grid has either the graphic or nothing. (Or it has the one graphic or the other, if that's a better way to go.)

Can somebody point me to a discussion of how to do this sort of thing in Silverlight?

Many thanks!
