In my project, I have implemented an ASP button which triggers a JavaScript confirm message on click. The issue arises when I realize that I want this alert to pop up only once all client-side validations have been met.
Any suggestions on how I can go about doing this effectively? My belief is that I may need to enforce page-level validation from the client side beforehand, and then proceed to showcase the confirmation dialog if everything checks out.
For those utilizing ASP.NET validation controls, make sure to include an OnClientClick event in your submit button code...
<asp:Button ID="blah" OnClientClick="if(Page_ClientValidate())return confirm('your message')" OnClick="your submit method" Text="submit" runat="server" />
Ensure that Page_ClientValidate() returns true after validating the page, and remember to return the result of your "confirm" function for the form to be submitted successfully.
