in a content page of an asp.net web page, i would like to include the "paypal" button "Pay Now".
So, i've a master page, and a content page.
In my content page i copy-paste paypal code.
In particular i use a "modalpopupextender" to permit my user to buy the object.
The problem is... it not work.
So my hypotheses are:
I'm not sure, but i think i can't use a nested <form action>
If not the first, maybe i can't use a <form action> into a modal popup ?
someone can suggest me an "elegant" solutions to solve this ?
Thank you ...
EDIT: in particular, what i'm trying to do is to permit to sell from a website.
I've a master page, and a content page.
Obviously in master page i've the classical "form action" .
Then i'm gone to paypal and got this code: "
<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_s-xclick">
<table>
<tr><td>
<input type="hidden" name="on0" value="Annuncio Premium">Annuncio Premium
</td></tr>
<tr><td>
<select name="os0">
<option value="Premium 1">Premium 1 €1,00</option>
</select>
</td></tr>
</table>
<input type="hidden" name="currency_code" value="EUR">
<input type="hidden" name="encrypted" value="-----BEGIN ">
<input type="image" src="https://www.paypal.com/it_IT/IT/i/btn/btn_paynowCC_LG.gif" border="0" name="submit" alt="PayPal - Il sistema di pagamento online più facile e sicuro!">
<img alt="" border="0" src="https://www.paypal.com/it_IT/i/scr/pixel.gif" width="1" height="1">
</form>
So i've pasted it into my content page ... as it... without changing.
In particular i've pasted it, into a panel, that will show whith a "modalpopupextender".
It works. But what it not work is when i click the paypal "Buy Now" button.
My web page don't redirect to paypal, modalpopup disappears and nothing happens.
I had this exact issue too and couldn't believe that PayPal had not provided some sort of solution for .NET developers!!
Here is how I solved it:
<asp:ImageButton ID="btnPayNow" runat="server" ImageUrl="myPayPalButton.jpg"
PostBackUrl="https://www.paypal.com/cgi-bin/webscr" OnClick="btnPayNow_Click"/>
Use an ImageButton or normal button and simply remove the form tags for the PayPal code, leave in the hidden input fields and the data will be posted to the PayPal url!
Nice and easy :)
Ps. The method 'btnPayNow_Click()' does nothing, signature exists but there is no logic in the code I have.
You are quite correct, in that you cannot nest <form>s.
Nor can you use the form action to create a popup - the action attribute is the url to which the form posts to.
You can, however, have many <form>s on the page, so long as they are not nested. Perhaps that will solve you issue.
Can you please describe exactly what you are trying to achieve? It is not clear from your question what the problem is.
If I understand the question correctly, you are trying to create a dynamic HTML popup window which contains a PayPal form. You are having problems because the popup contains a form, but the HTML for the popup is already contained within a form.
If the problem you are experiencing is what I described above, the solution is fairly simple. You need to move all of the HTML for the popup outside of the exiting form element. If you are using CSS to properly lay out your site, it should be possible to display your dynamic popup wherever you need to on the page using relative or absolute positioning. The HTML for the popup need not be contained within another form. It may also be possible (perhaps even necessary) to put the contents of the popup into an iframe, which can be submitted entirely independently from the rest of the page. The semantics of how your popup works would depend on how you need your page to function.
So, to be clear...it is not possible to nest form elements. However, it is also not necessary to accomplish your needs.
EDIT:
To improve the answer above in light of the updated question. You can have multiple content panels on a master page. It should be entirely possible to create another content panel that is outside of your form element in your master page...and place your modal popup inside of this alternative content panel. My above answer would then still apply, as you no longer have nested forms.
You are right in your first hypothese, you can't have nested form tags in a page.
You just have to put the code for the popup outside the form, you can have any number of forms in the page as long as they are not nested.
Dal's answer is correct! (not taking credit with my answer)
I had a similar issue in ASP.NET (4.0) when trying to submit data to SagePay (same as PayPal form posting). I was writing the form fields in dynamically using panels in the code-behind using
Dim Panel As New Panel
Panel.Controls.Add(New LiteralControl("My <input> controls HTML")) '1 control.add per <input> control.
MyDiv.Controls.Add(Panel)
I was writing the whole < form> dynamically also, so when it came to debugging I received no warnings regarding the issue that my entire Site.Master is within a - this is not visible from a .aspx page using the master as a template! It was quite frustrating... Until I read that you cannot have a nested < form>... There are only two alternatives to this:
1) move the form details outside the first that is within my Site.Master from the .aspx page itself. (I didn't like the idea of this, messy messy!)
2) create another control that is NOT a to post my data.
I chose the latter!
<asp:Button id="btn_payment" value="Proceed to Payment" Text="Proceed to Payment" runat="server" PostBackUrl="https://test.sagepay.com/gateway/service/vspform-register.vsp" />
The button posted to SagePay, took my dynamically generated fields (Called from the .aspx page) and as they were already within the from my Site.Master - all worked well! - I hope this helps anyone using dynamically generated HTML with forms.

Links from the menu are directing correctly but links like the one in the page below are SUDDENLY not.
http://tazara.mwanawanga.com/?page_id=94
I gave searched on this topic. I have tried reseting permalinks and deactivating/activating plugins. Neither seems to work. I have also tried changing the theme. Still nothing.
Any helpful suggestions are welcome
You have a problem with the form that does the redirect on that button. See below
<form method="link" action=" http://tazara.mwanawanga.com/?page_id=389">
<input type="submit" value="View fare charts and train timetables">
</form>
If you can see, theres a space in the action field of the form which will error the form's action and go to the root.
Try changing it for this:
<form method="link" action="http://tazara.mwanawanga.com/?page_id=389">
<input type="submit" value="View fare charts and train timetables">
</form>
The same will probably go for many other buttons on the site doing the same thing. I would personally recommend not using forms though and just creating a class which has the same styling as a form submit button and using a tags to link. It will be more search engine friendly and easier to use and maintain.
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.

I have a web page where I dynamically generate lots of elements from code behind and inject them into the page, as such:
input type="file" style="width:480px;" id="fileUploadLogo345">
I also have buttons for submitting, like this:
input id="Submit1" type="submit" value="Substituir Logo" onclick="return jsSubmitLogo(345);">
(The javascript function always returns true...)
No matter what I try, I am unable to get any of the uploaded files from code behind.
I tried adding enctype="multipart/form-data" to the form, I tried adding runat="server" to the file upload controls, I have no idea what else I could try. No matter what I do, in code behind Request.Files.Count equals zero.
Any idea what I could be doing wrong?
If it makes any difference, I am using a master page...
Thanks
You are using "id" attributes in your html... you should instead use "name" attributes, and everything will show up fine in code behind.
I have an asp.net page in 3.5 that I have a pay pal button on but when I click on the button it just refreshes the page. I think I need to encapsulate the paypal button in something so it is not trigging the refresh but goes to pay pal.
Anyone know a solution? Can I use an updatePanel or iframe?
I had this same issue once, I just used the following code for my button:
<asp:ImageButton ID="btnPayNow" runat="server" ImageUrl="~/images/Purchase/payNowButton.jpg" PostBackUrl="https://www.paypal.com/cgi-bin/webscr"/>
Hope that helps!
Paypal pay now buttons as generated by paypal site have their own form tags in. ASP.Net pages are generated with the whole page within a form, so you now have a form within a form which wont work. If you opt for a paypal hosted button you can have code like this within the asp.net page which will work:-
<input type="hidden" name="cmd" value="_s-xclick"/>
To order the item name for £99
<input type="hidden" name="hosted_button_id" value="note to programmer-this value is generated by paypal"/>
<asp:ImageButton ID="Button2" runat="server" PostBackUrl="https://www.paypal.com/cgi-bin/webscr" ImageUrl="https://www.paypal.com/en_US/i/btn/x-click-but23.gif" ImageAlign="AbsBottom" />
I know this is an old question, but I hope this helps someone else.

I would recommend you to use the PayPal Developer Toolkit for this. They're having a lot of good code samples and how to implement PayPal the best in your ASP.NET page.
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.
