Asp.net form submit action question

T

TheOne

In Asp.net web form under form tag there is action field that I am point to
some other page, and not to same web form. When I run this page it is always
pointing to itself. How do I get around this?

Here is HTML code from webform..

Thanks,

Sinisa

using the <form runat="server"> you *cannot" have a value for action. All
aspx forms must post back to the same page. If you remove the runat="server"
you may be able to do this; but you have stick to html controls

You've got to ger rid of the runat=server for the form. An ASP.Net form must
post back to itself to handle certain kinds of events, like catching a
button's click by the server.

I have to use server controls since I will be putting in user control for
it. Is it possible to use response.redirect to submit form? Is there some
other solution. Somehow I need to post information from this form.

Thanks,

Sinisa

AP.NET 2.0 solves this issue. However, its only in BETA. So, you can't
have the best of both worlds. Either you stick with the current model by
having the form post back to itself or do as we suggested. If that doesn't
work for you. Then maybe asp.net is not the right solution for you. Give
classic ASP a try. :)

To transfer to another webpage look into one of these three options:
Response.Redirect
Server.Transfer
Server.Execute

I'm trying to do something similar, to do a POST to paypal. In my quick
testing, I don't see that removing runat=server and using server controls are
mutually exclusive, it's just that you can't process any events from those
controls (which you don't care about, because you're off to another page
anyway).

In my test, I have a single placeholder on the form, and the <form> has
"runat=server" gone, method="post" and action="paypal, etc.". In the
code-behind I add htmlinputhidden fields to the placeholder for all my
name/value pairs (appears that I have to set id= for each, which sets both
name= and id=, not sure why).

When I submit this form it goes to paypal with the post values as planned.
Last piece I'm working on is to do the submit automatically, which per
various posts out here I think I can do as document.forms[0].submit().

hth,

What is the "proper" way to programmatically call another page in your app
while passing it information? QueryString has length limitations, Session
would seem to be an improper place for page-to-page, but Context.Items don't
actually get saved to the page source, so there's no "history" with those.
I'm curious what the right way is because I'm struggling with related
issues, and right now, I'm dropping a webcontrol on my pages called
ContextItemRetentionBlock that renders hidden inputs with those values to
the page so that they don't get lost with the context.

P.S. Turns out it was cleaner to build the whole "redirect" page strictly via
code in the helper class, e.g. "<html><body><form name= ...", etc., and
output the hidden fields as literal text in the middle.

Hi Sinisa,

Yes, currently the ASP.NET 1.x hasn't any buildin means for cross-page
posting. If you do need to cross-post to different page, you can have a
look at the following article which mentioned the scripting way:

#Post an ASP.NET form with JavaScript
http://www.codeproject.com/aspnet/jsnopostback.asp

Also, the ASP.NET2.0 does provide complete and great support on cross-page
posting. And provide more features on the cross-page interaction Model.

Thanks.
