I created a WebRequest to POST information. My objective is to emulate in C# a PayPal "buy now" button which is in html.
How do I get the redirect when sending the WebRequest? Simply having Response.Redirect doesn't work because I have to have the redirect with the information.
The code of the button I'm trying to emulate is:
<form name="_xclick" action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_xclick">
...
</form>
You can not do redirect with post.
What you can do: Make the actually post direct to the paypal, or redirect to a second page that re-create all the post data, and make automatic post with javascript.
An example of how to create a page with parameters that make automatic post.

Not sure you can do what you want from code behind. I had a similar situation where I had the form like yours besides the normal ASP.net form. I hid the non-ASP.net form through CSS so it's not in the user's face and then I triggered the POST via javascript (I put a button inside the form and then called buttonX.click(); )

In my web forms project (a forum) I have a form that is accessed through a link from another page, a link which includes parameters. for example:
EditPost.aspx?mid=0
When the page is loaded, the form hasn't yet been submitted and Request.QueryString contains the URL parameters I loaded the page with. However, after I send the form, Request.QueryString conatins the values of the form fields. This is a problem because I need the URL parameters after the form is sent.
The question is, how do i make the page send me those URL parameter with the form information?
If I'm approaching this wrong, and I'm supposed to keep the URL parameters from when the page is first loaded, let me know how.
Thanks!
Edit:
<form action="" id="f_editComment" name="f_editThread" method="post" onsubmit="return true;">
<%=ThreadTitle %>
<textarea id="body" name="body" runat="server"></textarea>
<input type="submit" id="submit" name="submit" />
</form>
In my project I want to run 2 forms in one webpage which is master page one is for contact us and one is for signup user. but multiple server side forms are not allowed. is there any solution for fix it?
You can use postback ability of Asp.net Webforms.
You should create one button for singup and another one for contact. You can catch event in server side and you do what want to do.
You can create regular client side forms created using HTML in the master page, and use the Request.Form to read the posted data. For this to work, all the input elements must have a name, and you can read them using Request.Form["ElementName"].
Take into account that forms cannot be nested.
So, your master page needs to llok like this
...
<body>
<form id="form1" runat="server">
</form>
<form id="contact" action="Contact.aspx" method="post">
<input type="text" name="Message"/>
<input type="submit" value="Contact us!"/>
</form>
</body>
The first <form> is the regular ASP.NET server side form, which supports server side components
The second <form> is a custom HTML form. It doesn't have the runat="server" attribute, and it's outside the server side <form>.
The second form action points to a .aspx page. In its page load event you can use the Request.Form["Name"] to acces the name of the contact form. Note that you also need to include a submit button to send the data to the server, and a method="post" to specify the method to send the page.
This is resorting to "basic" HTML controls, so there is no View State, and the posted values will be lost if they're not reset in the server. I.e. if the form is posted, and there's an error, the previously posted values will be lost when rendering the page again.
If you want to make it more sophisticated you can use Javascript and, optionally AJAX. But that's a more complex solution. See this for an example.
ASP.NET Forms only supports one form. You could use an iFrame and render your second page (second form) inside of the iFrame.
Here is an interesting post about placing some page content after the tag. This may be helpful to you.

Our company uses PinPointe for email marketing and we have a Drupal 6 site with several language domains. I have created a web form except I did not create any fields in Drupal. Instead in the node Edit NOT THE NODE WEBFORM EDIT....in the node edit for the body section I added the HTML and the javascript for form. Everything works well and the data is captured to pinpointe. The problem lies in the fact that the page..upon clicking submit..actually redirects to PinPointe where I get a friendly message saying. Thanks for joining. Well I don't want this. I would like to just pop an alert saying thanks and leave the user on the page they were on. I tried this code for using jquery to do the post but it isn't loading and I suspect that's because I need it in the header not the body.
So all I want is to submit the data to pinpointe and not redirect the user. So here is where my limited Drupal knowledge runs out:
If I create the input fields in the node webform then how do I get the form to post to pinpointe?
If I create the fields dynamically in the node body (not node>>webform) I can direct the submission to PinPointe but then how do I stop the redirect?
FWIW here is the jquery I was trying to use but suspect has to go in the header http://jsfiddle.net/4xDFK/4/
FWIW here is the code for the dynamic creation:
<form action="http://na04.mypinpointe.com/...." id="webform-client-form-1375" method="post" onsubmit="return CheckForm257(this);">
<div>
<div id="webform-component-UsrEmail">
<div id="edit-submitted-UsrEmail-wrapper">
<input id="edit-submitted-UsrEmail" name="email" size="30" type="email" />
</div>
</div>
<div class="form-actions form-wrapper" id="edit-actions">
<input class="form-submit" id="edit-submit" name="op" type="submit" value=" " />
</div>
</div>
</form>
Create your custom confirmation page in Drupal. Then set up PinPointe to redirect to this confirmation page.
In the PinPointe form manager, there is a option under the 'Thank you page options' to send a signup user to a custom URL.
Is it possible to post a form from one MVC site so that it invokes the POST action in a controller on another site ? I can do a GET easily, but a browser redirect is always a GET as per my understanding and I am unable to invoke the target site's POST action.
e.g. http:/siteA.com/test invokes http://siteB.com/result/signin ... in the ResultController, the Get version of the "SignIn" action gets invoked, but I need the "Post" version to be invoked as I need to pass in parameters in the POST header.
Currently I am resorting to using a GET and am passing params. using the query string which is not ideal for my scenario. Any help here would be appreciated.
You could POST using a simple form:
<form method="post" action="http://othersite.com/controller/action">
<!-- some input fields containing the values to post -->
<input type="hidden" name="param1" value="value1" />
<input type="submit" value="Post to other site" />
</form>
I used AJAX to invoke the target and bundled in the necessary parameters to post in there.
I am building a german payment provider into my site.
But when I click on "Submit", nothing happens. Can someone please help me? I think I've looked at it too much and I can't see the forest for the trees anymore...
<form method="post" action="https://www.sofortueberweisung.de/payment/start">
<input name="currency_id" type="hidden" value="EUR" />
<input name="reason_1" type="hidden" value="Zambuu" />
<input name="user_id" type="hidden" value="29593" />
<input name="project_id" type="hidden" value="80145" />
<input type="submit" value="Absenden" />
</form>
Okay, so it's a little bit unclear what I want, it seems:
I have a lot of asp-sites allready, and now I must send, however, the information that is given by the hidden inputs by post-method to the site "sofortüberweisung.de/payment/start".
However I can solve it, it's not nessecary, there is no need for a form-tag, if there is another solution (e.g. with the code behind).
So: How can I send a lot of post information (these here is only an exmaple, in the real site there are a lot more) with code and redirect it to the right site?
If the code you have provided is within a standard ASP.NET form, so that you have nested form tags, try the solutions provided to this Stack Overflow question.
If it is possible to have this page be a simple html form, that is another possible solution.
Your button needs to have the runat="server" attribute set and it might be worth doing the same on your form atttribute.
Also remember in asp.net webforms you can only have one form tag.
I've had this issue a couple of times before where when creating an HTML form inside an ASP.NET form tag, the inner form just wouldn't post out.
One solution for me was to adjust the ASP.NET form tag wrapper for that page (moving the close above the HTML tag).
Another (where I needed ASP.NET controls obove and below the HTML form) was to add an iframe, passing the parameters for the form post to the iframe URL. Using JavaScript, the iframe then used those parameters to post the form to a new window/the parent window. Probably better ways, but it worked for me.
