asp.net gridview: How can I have multiple button fields in one column?

I need to create multiple actions for a gridview - say, "Approve", "Deny", and "Return".

I can do this by creating a button field for each action:

<asp:ButtonField ButtonType="Link" CommandName="Approve" Text="Approve" /> 
<asp:ButtonField ButtonType="Link" CommandName="Deny" Text="Deny /> 
<asp:ButtonField ButtonType="Link" CommandName="Return" Text="Deny" /> 

However, this creates one column for each button.

Is there a way to have the same functionality, but combine them into a single column?
