I have a custom SPGridView I am using to display some User Profile data. I would like to add "(Empty)" which you can see in out of the box listviews on any list that has empty fields. This seems like such an easy task but I cannot figure it out. Has anyone ever ran

Hi,

You can create new control that inherit from SPGridView and than you have to override callbacks function for SPGridView.

Here is a similar thread for your reference:
