Select a row in gridview

I have a hyperlink in my gridview that when a user clicks on it, he/she is directed to another page. It is working great. However, I want to be able to redirect the user to another webpage depending on what row he selects. For example: If the row he/she clicks on is an apartment, then I want to direct them to apartment.aspx. However, if the row is a house then I want to redirect to house.aspx.

I am sure I can simply have it refer to a column in my database with that info. However, I can't see where I am able to do that. I hope I am making sense on this.
