Passing values from a datagrid using a Link Button

Question

Here's my scenario: I'm passing an object into a datagrid (one object per row). Each row represents a customer search object. I need a column that provides a link button to pass the object back to another method that will load their information on the same page. I'm not exactly sure how to do this with aspx and firing the code behind. If I can get from the datagrid to the code behind with the row object intact I will be home free! Thanks in advance.
