How do I create a templatefield column in a gridview that displays a value of "Yes" or "No"?

I need to create a templatefield column that displays either "Yes" or "No" depending on the value of a field (column) from a SQL command.  The SQL code begins: "SELECT [C_Code]..." and I need to display "Yes" if [C_Code] = -1 and "No" if [C_Code] = 0.  I also thought of creating some sort of eval field inside in the SQL command.

As above or if you want to do the processing in ASP.NET, you need to create a function which takes in the value from the database and returns yes/no. You can then call this from the templatefield.

Thanks, for the suggestions.  I ended up changing the templatefield's code so that a black "Yes" displays when the field equals -1 else display a bold red "No" .
<asp:TemplateField HeaderText="Is Active" >
   <itemtemplate>
      <%#IIf((Eval("P_Active") = -1), "Yes", "<b><font color='red'>No</font></b>")%>
   </itemtemplate>
</asp:TemplateField>
