Web Forms :: Using Iframe To Submit A Web Form With 4.0?

Apr 22, 2010 02:17 PM

This post is related to the issue of using javascript with asp.net form found here:[URL]I figured out that the issue I am having is not that the javascript cannot find the control but rather that the ajax frame I am using, for some reason does not allow me to find the controls.Here is how I submit my form in VS 2008 which is working fine:

<form id="form1" runat="server" target="ajaxFrame" defaultfocus="userName">
The ajax frame below, is on the login page right before the body closing tag:
<iframe id="ajaxFrame" name="ajaxFrame" src="" style="visibility:hidden;"></iframe>

When the user clicks the login button, all the vb.net code on the code behind page is executed and some hidden fields are populated with some login/user validation data. The iframe then takes the user name and password (using jquery and some custom javascript) and automatically redirects and login the user on another website where an asp/js login page is used.For some reason, this exact setup does not work with asp.net 4.0.


Web Forms :: IFrame Form Data Capture Upon Parent Page Form Submit Action

Jun 08, 2010 09:30 AM

I have a web form called default.aspx which has a form with user information. In addition to this, I have an iFrame on the same page that displays a page Secondary-Form.aspx that has a few additional dynamic data fields. I need to do two things.

1. I need to pass the parent form data in real time to the iFrame page to refresh its content and modify it's fields accordingly. Example: If the user submits their Vehicle Choice as Car on parent form, the form item in iFrame will display a radio button that says Honda, and if the user submits their Vehicle Choice as MotorCycle in the parent page, the iFrame will display Harley Davidson as the radio button choice

2. The submit button is on the parent page. I want both pieces of this information (from the parent page, as well as iFrame selection) to be passed to a server side ASPX page to process this information.the default.aspx and Secondary-Form.aspx files are located on different domains.

MVC :: Submit Form Without Using Submit Button?

May 22, 2009 06:47 AM

Is there a way one can submit a form using an actionlink instead of submit button (I know one can fire a controller action with an actionlink, but not how to submit the form and all it's values)

Reason is that I have several forms that are supposed to have submit buttons, and also a "cancel" link which fires a controller action. These "buttons" need to look the same, and the only way to have "multiple submit buttons" is placing them in forms. This works, but make styling very hard.

Seeing one do have so many options styling links, I'd like to make all my submit buttons actionlinks instead.

Web Forms :: Forcing Postback Of IFrame Form

Jan 06, 2010 08:39 PM

I'm trying to solve a problem and am open to any suggestions. Here's the situation:

I have a checkout page that has an iFrame that contains a credit card form. The credit card form resides on an external site that is PCI compliant (and it is a requirement that we are PCI compliant so having the credit card form on our domain is not an option). When the user submits the checkout form, I need a way to force the submission of the iFrame form on the server side. This is because I need to wait for the credit card form's site to send back a reply via a web service on my end, which will be passing a token that I save and use later on when the order is submitted. I also will display any validation errors that are reported from the credit card form site, also via the web service.

This all worked just fine in a simulation, but I'm getting permission errors trying to access the form in the iFrame across domains (and after researching this, apparently it's not possible to access an iFrame's document across domains). I need a way to force the submit of the iFrame form on the server side without having access to the form itself. Can this be done? Can anyone suggest an alternative to what I'm trying to accomplish?

Web Forms :: Button In A Form That Does Not Submit?

Aug 26, 2010 07:44 PM

I've been trying to figure this out all afternoon but my google-fu seems to be failing me. I'm setting up a page with a fairly large form, which has one field that is going to require some kind of popup page that will allow the user to perform a lookup.

At the moment I'm only prototyping the page so I'm actually only attempting to a the button up to fire an alert when the button is clicked instead of generating a lookup screen. However it seems that no matter what I do the button causes the form to submit.

I remember one of the very first ASP .NET beginner videos I ever watched went through configuring a button to perform actions without submitting, but I can't seem to figure out which one it was.

Web Forms :: How To Fill A Form And Submit For An External Site

Oct 02, 2009 04:45 PM

I am relatively new to working with asp.net sites. What i need to do sounds fairly simple but i think i have a comprehension gap.

I am trying to write an application that will go to a specific site and basically "enter the form fields with the specific user name and password and then click the Login button" (by this mean supply the credentials and then trigger the event). I know that there is a hidden _EVENTVALIDATION Field, i don't know if that will effect what i am trying to accomplish.

When you enter the username and password fields and click the Login button, you are automatically redirected to a second page. This second page is where i want to get to as there are two files that i want to download from there. What i originally tried is the System.Net.WebClient object to use the method Download file. When i did that the files i DLed were considered corrupt. So i believe that i needed to complete the login procedure to be able to download these fields.
