Add DropDownList to a gridview cell

Question

I'm trying to do a DropDownList in one cell of the gridview but I only can add columns.

<Columns>
     <asp:TemplateField>
         <ItemTemplate>  
             <asp:DropDownList  ID="DropDownList1" runat="server" DataValueField="Catalog" DataSourceID="SqlDataSource1"></asp:DropDownList>
         </ItemTemplate>
     </asp:TemplateField>
</Columns>

How can I add an only dropdownlist to a gridview?
