    Hello!

    I'm trying to hide the submission button at page load if my databinded, hidden field named 'StateNotAvail' = True. This is on step 2 of an online quoting process, so some info is collected on step 1 and then passed through SQL for some quoting, etc, and then I'm using databind to populate some hidden fields to continue the quote process (on a separate page). One of the pieces of info collected in step 1 is the State that the customer resides in. There are a few states that we do not provide our product to, so on the 2nd step I have a message that is displayed based on a hidden field that is databinded after a lookup is done against my database. On top of the question event that shows the html field with the 'state not available' message, I have another question event that hides all other fields if state is not available.

    What I need to be able to do is also hide the submission button in this case, however since it is not an option during a question event it gets a little tricky. I have the following set up in the Initial Javascript for the module, but apparently this happens before the databind which therefore does not pick up the value of the hidden field.

    if ( $(StateNotAvail).ToUpperCase() == 'TRUE')
    {
    hidehtml('SaveForm')
    }
    else
    {
    showhtml('SaveForm')
    }


    How else can I accomplish this??


    Thanks,
    Doug

    Hi Doug,
    Can you put your sample on BetaSprings where we can look at the code? I think you probably have something missing in your javascript. If you run your code on firefox you can use firebug to inspect the elements and see better what is going on. The login for www.betasprings.com is host,dnnhost. If you make a sample of your code there something like Doug'S Javascript then let me know.
    Thanks

    That same code works as a client side event, would it need to be any different in the Initial Javascript section in the module settings? The design doesn't quite work right when 'hiding initially' and then displaying based on a client side event, though.

    If I used an HTML field with my button image in there, is there a way to make the image a link which submits the form (while still passing all the session variables)?? If this is possible, I could then hide this field along with all the other ones in my question event that looks at the StateNotAvail field.

    Anyone know if this is possible?

    Hello Doug,

    Perhaps you can find the ID of the DIV tag around the submit button then use:

    IF($(StateNotAvail).ToUpperCase() == 'TRUE')
    {
    document.getElementById('IDOfSubmitButton').style.display = 'none' // hiding submit
    }
    ELSE
    {
    document.getElementById('IDOfSubmitButton').style.display = ''; // showing submit
    }

    Let me know if this helps.

    Thanks,

    Ryan

    Ryan,
    Clever approach, but unfortunately the button remained regardless of the value of the hidden field

    I tried plugging in the DIV ID as well as the ID of the image field to your script, both no dice.

    I did see this is the source:

    onclick="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("dnn$ctr2431$DynamicForms$imgSave", "", true, "DynamicForms_2431", "", false, false))"

    Any way to incorporate that into an HTML field with an image link?

    Ryan,

    Thanks for the example. I understand how to get it to do that, and have it working as a client side event. The reason this won't quite work though in my case is because if I have the button hidden initially and appear once the final question is selected, the user may change their answer to a previous question, which requires another postback and therefore re-hides the submit button, however when my final question has only one option, it remains selected but with no submit button. Does this make sense?
    Basically going off of your example, what I need is the value of the Yes/No question read in from a databind, and the visibility of the submit button then determined by that when the page loads. If you could get that working that would be fantastic!!
