a text box within a gridview

I have the code listed below, but I want to put a text box with a submit button within my gridview (gridview is blank by default) on submit the page refreshes with the gridview and its populated. but I also want to include a textbox with a submit button above the gridview
but anytime I try to put code within the gridview I get errors...what am I missing?

<table cellSpacing="0" cellPadding="0" border="0" width="400">
    <tr>
            <td width="10"></td>        
        <td><span class="regularBlackTitle">Currently there are no records that match your query.</span></td>
    </tr>
</table>        
</EmptyDataTemplate>
