I have a form in asp.net containing more than 20 textboxes. I have to use POST method to send only some of the parameters to payment gateway. Is there any way so that only required parameters from the form can be posted to payment gateway? Any help will be appreciated.

You could either make an explicit post with the values you want e.g. using jQuery (see jQuery.post()) or copy the values to another form that contains only the values of interest and submit that one.

How can i copy values to another form?

I am looking forward to use Webclient.uploadValues() method. msdn.microsoft.com/en-us/library/9w7b4fz7.aspx

do you want to submit the form from the server or the client? Maybe I misunderstood

Actually in the sample program, they have just given plain html code with all parameters in form with Method = post attribute. So i guess its from client. Correct me if I am wrong.
Have you tried just posting ALL your web form elements to the payment gateway? Chances are their page will just use the parameters they are expecting to receive and just ignore the others (that is the default behavior in web pages, interpret what you can and just ignore the rest).
If so, you would just need to make sure the client name of your form elements matches the name of the parameters the payment gateway is expecting to receive.
Since it's a webforms application, you may want to look at How to: Post ASP.NET Web Pages to a Different Page on the MSDN.

ya but the form contains some sensitive information such as password which i feel like need not be posted.

but do you need to "post" at the client side and directly show the resulting page to the client's browser? I'm asking because I've implemented integrations with a couple of payment gateways (of the kind where you redirect the user to a bank's site to perform the payment) and the flow was in both cases: 1. perform a post from the server side (i.e. not from the client's browser to prevent a technically savvy user tampering with the request) 2. receive back (server-side) a form of transaction id from the bank 3. redirect the user to a bank's page to pay for that specific transaction ID

So are you telling that i should post from server side using some c# function and not using javascript or post method from client browser? If so how can i achieve that?
Paolo Falabella
I'm not sure, it depends on the flow that your payment gateway requests. I was asking you to clarify what you needed to do. However, One of the payment gateway integrations I implemented is in c# and open source. The "sendMessage" method here is the one that performs the first (server-side) post
input-element without a name-attribute wont be submitted, so just remove the name-attribute on those fields and your fine.
