In the upcoming release of jQuery controls (2012.2 - very soon), you will be able to identify an unrelated column with which you can solve your case.
What @Boone offers will be absolutely correct - the only difference is that instead of a data-bound column (ProductID in this sentence) that will display these column values ββin the grid, you can define a space for the column.
You can then define a template for this empty (non-data-related) column in which you can place links, buttons or anything else that you like.
