Validation controls in a DetailsView EmptyDataTemplate

I'm using the following code to add/edit a project and I can't get the validation to work consistently. It works fine on the edit, but unfortunately that's kind of after the fact since the user isn't supposed to be able to add a project without a project name.

Histretch73 ,

I notice that you used asp:CustomValidator in EmptyDataTemplate, try to use RequiredFieldValidator instead.

Instead of CustomValidator try using RequiredFieldValidator to validate yourtxtProjectNameAdd TextBox

<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ErrorMessage="A project name is required to add a project." ControlToValidate="txtProjectNameAdd"></asp:RequiredFieldValidator>

Needed to add the validation group attribute to the requiredFieldValidator. Duh. Thanks for the responses.
