As I Said...
Update: The source is now live!
I mentioned yesterday how I'm not especially great at ASP.net. Well the update I did last night to Gaptcha proved it :) I added the 'Get more pictures' link to the Gaptcha control, but it only worked if you had text in the comment field, because the validators kicked in.
Thanks to some advice from Bernardo Hynemann, I've seen just how easy that is to fix :)
My link button now has the ValidationGroup attribute set (with a value of "SomethingDifferent" just like he suggested *grin*) and now it works a treat.
<asp:LinkButton ID="btnNewSet" runat="server" CssClass="CommonTextButton" ValidationGroup="SomethingDifferent">Get some new pictures</asp:LinkButton>
I really must get around to learning these validators...it looks like they're quite handy :)
(Oh, before you say anything, I know what they are, I already know they're useful, I've just never used them before. Sorry, it's just sometimes people take me literally at my word and I get a very basic lesson sent to me about what something is :)
