From client, force whole page validation

I have an ASP button for which I have set the OnClientClick property to display a javascript confirm message. However, I only want this message to be displayed AFTER all of the client side validations have passed.

How can I do this? Essentially, I believe that I need to force Page level validation from the client and then, only if it passes, display the confirmation box.

Solution

  • If you're using the ASP.NET validation controls add an OnClientClick like this to your submit button...

    <asp:Button ID="blah" OnClientClick="if(Page_ClientValidate())return confirm('your message')" OnClick="your submit method" Text="submit" runat="server" />

    ...Page_ClientValidate() will return true if the page is validated then you need to return the results of your "confirm" in order for the form to be submitted.
