>Instead of getting the Listtems for the DropDownList from the DB would something like this work:
<asp:TemplateField HeaderText="Allow / Deny">

>              <asp:DropDownList Id="AllowDeny" runat="server"

>                 <asp:ListItem Value="0">No</asp:ListItem>
>              </asp:DropDownList>
>          </ItemTemplate>
></asp:TemplateField>
What I want to do is create a grid with the name of an access right and a combo that says "Yes" or "No". In the dataset there is a
column called AllowDeny with 1 or 0. I want the combo to be bound to the AllowDeny column, so that for each row, Yes shows if
the AllowDeny column has a 1 in it, and "No" shows if AllowDeny is 0.

I could also use a checkbox if that's easier.
Everything makes sense in someone's mind

In addition, an integer field is not for irrational people
