Prevent multiple submits from the finish button in a wizard

Posted on 2006-11-29

Hello Experts,
I have a registration page that I set up using a wizard control. The only problem is sometimes the user clicks the finish button more then once
and I get duplicate records in my database.  I've found tons of posts on disabling a submit button but it seems like it's a little harder then throwing some javascript on a submit button.  I'm having a hard time accessing the finish button within the wizard to even disable it.
Any help would be appreciated.

You should be able to just set a Session variable on the first submit and check this with each submission to see if the form has already been submitted:

    protected void Page_Load(object sender, EventArgs e)
        if (Page.IsPostback)
            if (Session["submitted"] == null)
                Session["submitted"] = true;
                // Database work
                // Page has been submitted once, show message, etc
