same as you would were it outside a gridview...

<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="txtKeywords"
        ErrorMessage="YOu forgot to type something" Width="304px"></asp:RequiredFieldValidator>

Outside of the gridview tag, it doesn't make up part of the control. Just so long as it references the correct control then all is good.

</Fields>
</asp:DetailsView>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="txtKeywords"
        ErrorMessage="YOu forgot to type something" Width="304px"></asp:RequiredFieldValidator>

The control would be a textbox for example (not the details view) so make sure the control has an id value

where can i make sure it has an id value  ? WHen i created it i just used the details view template, when i go to click on the textbox in the properties window under fields it just says (collection)
so how do i access each field's id value to set the validator to the right field?

Are you using visual studio 2005? if so, select the details view in design mode and then click the smart tag and choose edit fields. Select the field in question and select convert this into a template. Close this dialogue box and then reopen it but this time choose edit templates. Your control label/textbox/whatever will now be shown as a single entity rather than the details view as a whole. Highlight the control and then give it an id in the properties window
