How do I add a footer that only has a button and the footer spans the entire row?
<p>The closest I've been able to get is the following:</p>

<pre><code>&lt;asp:TemplateField FooterStyle-CssClass="PagerNavigationButtons"&gt;
&lt;FooterTemplate&gt;
&lt;asp:ImageButton ID="DeleteReview" ImageUrl="~/DeleteReview.png" runat="server"/&gt;
&lt;/FooterTemplate&gt;
&lt;/asp:TemplateField&gt;
</code></pre>

<p>This however will create a new blank field (and row) and put the button only at the bottom of that field.  I haven't had much luck finding something so obvious through Googling either.</p>
