Contour stores your progress in a cookie, the logic being that once you complete a step you shouldn't have to see it again. I don't know if there's an easy way to make a "go back" button. What you could try is to somehow detect that there's no querystring and delete the Contour cookie. However, any information that was previously entered will probably also be lost.

Would love to know if there's a better way though, a "back" button would be good. Maybe it's possible to delete some information in the cookie and still keep the previously entered information. Have a look at the info in the cookie and in your viewstate to find out more about this.

Sebastian, Greg,

I had this issue with with the step form hack i did  you could half fill form and close it then re open and the form would open on correct page but the steps would be out of synch so i had to read the cookie and then restore the step to the correct step in the step bar.  

public string StepCookieName { get; set; }

protected override void OnLoad(EventArgs e)

        {

            if (!IsPostBack)

            {

                SetViewStateCurrentStepFromCookie();

            }

 }


private void SetViewStateCurrentStepFromCookie()

        {

            //if resumed form get step value from cookie

            if (Request.Cookies[StepCookieName] != null)

            {

                int stepId = 0;

                if (!string.IsNullOrEmpty(Request.Cookies[StepCookieName].Value))

                {

                    int.TryParse(Request.Cookies[StepCookieName].Value, out stepId);

                    if(stepId!=0)

                    {

                            ViewState["pgv_pageindex"] = stepId;

                    }

                }



            }

        }

please note i created my own form control that inherits from contour form control and i put in my own logic by overriding page_load see here for what i did.

I had to do some crazy stuff with contour last year. Maybe this will help:

http://www.farmcode.org/post/2010/03/26/Regionalizing-validation-messages-and-regex-in-Umbraco-Contour.aspx

I'm not sure about the new Contour, but the last version puts a file called RenderForm.ascx under \usercontrols\umbracoContour\ in your project. You can write your own codebehind to inherit from Umbraco.Forms.UI.Usercontrols.RenderForm, where you can override the prerender event of the form to do anything.

Anthony,

Exactly what I did so that i could do contour multi step form which has a stepbar showing progress.

Ismail

So you can still do that with the current version of contour. Nice!

UGGGHHHHHHHH... stupid forum keeps ditching my posts.. its happened to me at least a dozen times now.  SO frustrating.

I'm stuck with the cookie.. I dont have any cookies with an integer value that look like they'd be storing the current step.

Ismail, i notice you have a public property "StepCookieName"... where are you setting the value of that?

Is the current step maybe getting stored in the session, and not a specific cookie?

Any other suggestions how i can determine which step we should be at in the form?

Ismail, I notice you check the following viewstate value: ViewState["pgv_pageindex"] ... but it seems to be always null for me... is this the correct value?

Ugh, i'm really stuck with this.. i wish i had the source code to figure out what contour is doing, and how it's loading the form steps.  really hoping somebody can help me with this soon :|

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 9.5px Consolas; color: #ae211f} span.s1 {color: #000000}

Hi Greg,

That's the way it's setup, when a person enters a multistep form and doesn't get to the end, the next time he goes to the form he'll resume the record ...

There is no default way of disabling this. What you could to is add some code that removed the cookie when the pages loads (initial load not on a postback).

Regards,
Tim

Yeah, that's what i'm trying to do Tim, but what cookie is it?  I dont seem to have a cookie set that has an integer value that would represent a step number... sure its stored in a cookie?

Hi Greg,

The cookie stores the record id , cookie name format should be like this:

contour_pageid_formid

But be sure to only remove it when it's not a postback, since it's also used for the navigation between steps

Yup, found the cookie... but clearing the value does not cause the form to go back to the beginning.  Do i need to reload the page?

Egh... I'm setting the cookie value to null, then redirecting back to the the same page (reloading it), but contour is resetting the cookie on each page load...

That shoudln't be a problem, it should create a new record instead of resuming the old one

Perhaps, but how do you suggest i reload the page?  calling "Response.Redirect(Request.Url.ToString());" causes it to get stuck in an endless loop cos i'm checking if the cookie is set, if so delete and redirect.

I guess i could force a postback via a javascript call, but that's just getting really ugly. :\

        protected override void OnLoad(EventArgs e)
        {
            if (!IsPostBack)
            {
                if (Request.Cookies["contour_1353_2843a2da-fc6a-4229-ab59-5d8f3b552c7b"] != null)
                {
                    if (Request.Cookies["contour_1353_2843a2da-fc6a-4229-ab59-5d8f3b552c7b"].Value != null)
                    {
                        Request.Cookies["contour_1353_2843a2da-fc6a-4229-ab59-5d8f3b552c7b"].Value = null;
                        // Contour resetting the cookie, so getting stuck in endless loop...
                        Response.Redirect(Request.Url.ToString());
                    }
                }
            }
        }
 

Also, i've found teh form Id (Page.FormGuid i think it was).. how to get the page id?  can't find the umbraco api doco right now.. :\

reference umbraco.dll

and then you get get it trough

umbraco.presentation.nodefactory.node.getcurrent().id

(not 100% on the casing but it should get you there ...)

Yup thats the one thanks... so i'm getting the cookie name no probs:

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 9.5px Consolas}
p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 9.5px Consolas; min-height: 11.0px}
span.s1 {color: #4200fe}
span.s2 {color: #49a2bc}
span.s3 {color: #ae211f}



        private string CurrentPageCookie
        {
            get
            {
                int pageId = umbraco.presentation.nodeFactory.Node.GetCurrent().Id;
                string formGuid = this.FormGuid;
                return String.Format("contour_{0}_{1}", pageId, formGuid);
            }
        }
 

But still not sure how to go about forcing contour to start at the beginning of the form once i've cleared teh cookie... I've added a new session variable to check against, to prevent the endless redirecting loop... but contour is still not starting at the first step.  Here's my code:

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 9.5px Consolas}
p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 9.5px Consolas; color: #009200}
p.p3 {margin: 0.0px 0.0px 0.0px 0.0px; font: 9.5px Consolas; min-height: 11.0px}
span.s1 {color: #4200fe}
span.s2 {color: #49a2bc}
span.s3 {color: #ae211f}
span.s4 {color: #000000}



        protected override void OnLoad(EventArgs e)
        {
            if (!IsPostBack)
            {
                if (Request.Cookies[CurrentPageCookie] != null)
                {
                    if (!(Session["Redirected"] != null && (bool)Session["Redirected"]) && Request.Cookies[CurrentPageCookie].Value != null)
                    {
                        Request.Cookies[CurrentPageCookie].Value = null;
                        Session["Redirected"] = true;
                        // Contour resetting the cookie, so getting stuck in endless loop...
                        Response.Redirect(Request.Url.ToString());
                    }
                }
            }
            else
                Session["Redirected"] = false;
        }
 

The logic is working fine, its clearing the cookie once, redirecting, reloading the page, and on the second time skipping the cookie clearing and redirect operation, but still its skipping the first step. 

What am i missing??

Here's the full code:

    public partial class KIND_RenderForm : RenderForm
   {
        private string CurrentPageCookie
        {
            get
            {
                int pageId = umbraco.presentation.nodeFactory.Node.GetCurrent().Id;
                string formGuid = this.FormGuid;
                return String.Format("contour_{0}_{1}", pageId, formGuid);
            }
        }
        protected override void OnInit(EventArgs e)
        {
            base.OnInit(e);
        }
       protected override void OnLoad(EventArgs e)
        {
            if (!IsPostBack)
            {
                if (Request.Cookies[CurrentPageCookie] != null)
                {
                    if (!(Session["Redirected"] != null && (bool)Session["Redirected"]) && Request.Cookies[CurrentPageCookie].Value != null)
                    {
                        Request.Cookies[CurrentPageCookie].Value = null;
                        Session["Redirected"] = true; // To prevent getting stuck in endless loop...
                        Response.Redirect(Request.Url.ToString());
                    }
                }
            }
            else
                Session["Redirected"] = false;
        }
    }

So.... no suggestions?  The original one of clearing that cookie clearly doesn't work.

It'd be awesome if somebody could look at the source code of Contour and tell me how it's establishing at which step of the form it loads.

I just thought of something.. perhaps i should set the expiry date of the cookie to a time in the past instead of clearing the value... maybe that'll force contour to start the form again... what do you guys think?  (can't try it now, dont have my dev machine with me unfortunately)

Hi Greg,

I'll take a look at how you can do this and get back to you with a solution (will be on monday or tuesday).

Cheers,
Tim

Thanks Tim - you're a champion!!  

I can't believe i was so close... i'd thought about expiring the cookie instead of deleting it, but didn't add it back in... doh!

Thanks again for the fantastic work.. well deserved karma coming your way :)

is working on a reply...
