I have 2 textboxes on a page, but both textboxes form part of a string which is stored in the DB (called Staffware Ref):
<asp:textbox id="txtConnStaffwareRef1" runat="server" CssClass="ihd-input" MaxLength="3" Width="27px"></asp:textbox>
-
<asp:textbox id="txtConnStaffwareRef2" runat="server" CssClass="ihd-input" MaxLength="5" Width="40px"></asp:textbox>

So the textboxes are rendered on the screen as textbox1 (followed by a dash) then textbox2. They form 2 halfs of the resultant string.

Is it possible to check that both textboxes are populated at the same time and NOT as 2 different textboxes? So the message would simply say "Problem with Staffware Ref" if either textbox1 or textbox2 were empty.
Thanks. Andy.

Using the validation controls for client-side validation if you use required field validators on each textbox you'll end up with two messages. So you'll probably want to use the custom validator control that checks both but only shows a single message for either textbox error condition.
