How to define a composite|multipart DataKey in DataGrid object.

So far I cannot find any examples of how the DataGrid object handles multipart|compsite primary keys using the DataKey property?
Can someone please provide example code?

I haven't downloaded the v2.0 beta to try out the new datagrid (which supports composite keys), but if you're still using v1.1, here are a couple of workarounds:
