I want to be able to post my form data to another page based on the result of a validation done on server (and not via javascript). As an example, let's say the user captures a customer number and then captures the phone number of the customer on page A. When the user clicks on the submit button, the page posts back. Then, in the button click event, I need to check in the database if the customer number exists. If it exists, I need to post the data to page B so that user can input the next information. If it does not, I need to stay on the first page and show an error message telling the user that the customer does not exists.
I do not want to use Response.Redirect cause that would mean that page B would lose the form data coming from page A. I know about crosspage postbacks but that just turn the problem the other way around (if I post directly to page B, how do I get back to page A with the form data and show the error message?)...I know about Server.Transfer too but I would like to avoid that method because I know there are down sides to it too...I tried setting the button target URL to page B after validating from the database but it does not automatically redirect to Page B, it still shows up Page A and then if you click again on the button you are taken to page B. I know I could setup a javascript to automatically call the click on the button to post the page the second time automatically to the Page B but I don't like that method (if the user has slow internet, he sees the page twice and once the user is on page B, he can't use the back button cause he would be automatically redirected back to Page B because of the script).So, is there a way to change the request target after the button's click code has been handled???
When the users presses submit, I get the below error and for the life of me cannot figure out why! I have tried GET as well, byt that just seems to post to itself and just puts the form vairables in the URL rather than going to formprocess.aspx.page you are looking for cannot be displayed because an invalid method (HTTP verb) was used to attempt access.Please try the following:Contact the Web site administrator if you believe that this request should be allowed.Make sure that the Web site address displayed in the address bar of your browser is spelled and formatted correctly.HTTP Error 405 - The HTTP verb used to access this page is not allowed.Internet Information Services (IIS)
I'm migrating an old ColdFusion site to ASP.NET. One of the pages has a form that posts to an external URL.
[Code]....
I just discovered that you can't do this in an .aspx page. Seems the page will just post to itself if you hit the submit button.What's the proper technique for achieving this in ASP.NET? There are a couple of hidden fields that pass parameters to the external URL.
i have a PayPal button, and i've been trying to add it to my site, but since my page is in a masterpage, and ovcourse, the form tag is editable only in masterpage, theres no way i could add the code inside the form tag, as so:
I have an asp.net application in which I have a parent form and in that on load I am adding sub forms dynamically having a submit image button..
When I am clicking the button of one form then I am able to read the hidden variables using request under parent form .But on clicking the second button the hidden variables of parent form are having null value although i have assign the value to them using context variables.
how can i handle mulitple form action for same page
asp.net with vb. I thought this would be easy but have been reading for an hour and not found out how to simply repost a page where form data has been entered and return the page with some error messages about what was entered. I want to return the page with all input controls with the data just as the user entered them before submitting. the error messages are labels that were blank when the page is first loaded. preferably the page returns focused to the topmost error error message. if that can't be done I would populate some label at the top of the page with something to the effect that 'errors were found, scroll down to see the errors'
I don't know it's even possible but I try to achieve to post data from one page to another using the second form.The problem is I need a form tag for the user interface containing callback panels etc. I want to put a second form with some hidden-field:
Is there a way to force a non-secure form post to be secure? I understand there are ways to automatically resolve an http URL as an https URL but with form posts, is this type of redirection too late? Will the posted data have already gone through the wire as plain text?
I need to know how to post information from an HTML <form> to a page that's within an IFRAME on an external server. In other words, the page with the <form> is on the first server, page being posted to is on the second server within an IFRAME which is also on the second server.
I've seen snippets of code for posting to a page within an IFRAME, but I believe that these apply to an IFRAME and target page on the same server as the posting page.
I notice on some sites i can login wrong which brings me to a login page. log in incorrectly again which brings me to a wrong password page (where i can log in) and if i login wrong again i dont increase my page history count. It takes exactly 2 backs no matter how many times i get it wrong and i dont see any pages in my forward history
Currently whenever I need to send a request to a payment-gateway, for example, I redirect my page to another page on my website which has a form with several hidden fields. I then pre-populate the values of these fields server-side, and specify in the body tag something like 'onload="form.submit();"'
However, I'm wondering, rather than redirecting to this page, is there anyway that all this data can be collected and POSTed to the payment-gateway server-side?This will cut out the need to redirect the user to this blank page, and make everything a bit more tidy.
I hope this is a really easy question but I'm struggling with it. I have a GridView that has an UpdatePanel within a TemplateField.
The idea is that the user can make simple alterations without a full page load being required.
I have simulated my page functionality in the following example, which simulates a database hit, gridview databinding and updatepanel functionality.
When you press any of the + or - buttons in the GridView, the form controls in the bottom UpdatePanel also post their contents back. I have seen this by using Firebug. On my real page however this is causing excessive bandwidth and is nearly the same as a full postback.
how I can force ONLY the appropriate UpdatePanel's contents to postback for processing, rather than all the UpdatePanels?? I've tried experimenting with Triggers but just can't get it working properly.
We have a website that processing products from various web shops! Users of these web shops can send products for our site what will store these products in our database. Users are sending in products through the post method of the form, and within the form the data is in hidden imput fields! Our site using UTF-8 charset, and this service is working like a charm together with other pages that has utf8 chaset too. The problem comes when someone using our service from a site that has other charset then utf8, for example: iso-8859-2.This case the special hungarian characters, like "íéáűőúöüó" are replaced with a '�' character!We have tried to convert the incoming string on server side but that case the '�' has been replaced by '?'. - still not acceptable :)
Why is it not possible to post my form from an iframe? The form in the iframe is the same as the form outside the iframe. I have put in the EnvableEvent Validation="true". It is not working.
I have done much searching and tried capturing javascript keydown events and such but cannot seem to stop a form from posting upon the user typing the ENTER key. I am using VB with VS 2008 SP1 and .NET 3.5 SP1. However, the ENTER key should function properly within a textarea input. So I have refrained from placing the keydown event in the Body tag.So I have wired up keydown events in 6 <asp:textboxes> that use the AutoComplete Extender. The javascript called is:
function on_keydown(e) { var keynum; var keychar; var numcheck;
Hope this is the right forum to ask. I am trying to write a simple mobile application with two form fields that POST to a webservice that queries an SQL database and comes back with an XML file that needs to be parsed and displayed properly in a browser.
So what I have is a webservice .asmx file that is working properly and an HTML form that POST two variables to the webservice file. The result is the generated XML. I simply just need to know the simplest way to display parts of that data as output within the design of the form page.
Here is the HTML form: http://www.bt4u.org/ And here is the web service: http://www.bt4u.org/BT4U/BT4U_WebService.asmx
If you enter in the following respectively you will see the XML file:
MSS-1607 HWD-2104
there is some sort of class that stores the XML in an array or some such thing that can then be manipulated
i m facing this problem for sum time now, and not found a solution yet.here it goes i have a webform on on which i have certain input fields,and a button trick here is i also want this form to connect to a payment gateway so i want this form to post some values to payment gateway, so on button click first it shouldsave the date and then post values and redirect user to payment gateway, during my tries i found out, it will only do one of the two if i specify form actiona and form method it will not save the data but directly redirect,which is not correct,i want both things to happen saving as well as post to payment gateway
I work on a HR application for Internal people.One of my staff member is caliming that he applied for a job, but we do not have any entry in the database for applicants and no error in Log4net.
The staff member calims that he clicked on the Apply Button. And when we checked the IIS log we found one entry by that user in the IIS event viewer. Now how to determine if the person actaully clicked the apply now button or not.This is a serous issue for us as he is very upset as the Advertising for that position is taken off and he cannot apply now.
How to investigate? Also does IIS logs all POSTS and GET Requests?ur system Admin passed me an error log from the event viewer.Which is something like this:
2010-05-05 00:28:57 172.10.12.30 POST /HROnline/Recruitment/Apply.aspx rk=579&pid=0 8600 INTERNALMIISNY 172.20.102.50 Mozilla/4.0+(compatible;+MSIE+7.0;+Windows+NT+5.1;+Trident/4.0;+.NET+CLR+2.0.50727;+.NET+CLR+3.0.4506.2152;+.NET+CLR+3.5.30729
Using .Net framework 4.0I have a .net search application that reads values from regular html webforms submitted via the Post method. So the code to process these forms uses Request.form and looks like
[Code]....
I am writing a new .net application that needs to call this same search application.
See what happens when you answer my questions! I come back! No good deed goes unpunished. I've built an Update form where my visitor can update data in dbase. I have a formview with several dropdown lists; none of which will update the table (all the textboxes, checkboxes and even Ajax enabled calendar work just fine). In the form below, visitor selects a CareerCluster from the ddl. Upon postback, the next ddl (pathwayListBox) populates with related data using the CareerCluster.selectedvalue in a query. At the same time, tsaOrgsDropDownList is also populated based upon the first ddl (CareerCluster).
When user selects from the tsaOrgsDropDownList the final ddl (tsaDropDownList) is populated. All this various selecting/populating works just fine on the form. The problem is: Nothing is updated to the table upon clicking the Update button. All other form fields do post as their supposed to except, I have other ddls on the page that are not related to the above series and they won't post either. My thought is that somehow, this is related to the postbacking going on. That posting back is overwriting the selectedValues with null or something.

I need to delete all the item what I seleted or I Checked.so I collect all the ID I selected .
then what should I do next?I could not find a submit button to send them,they are not in a from.So I try to collect them to a JSON object and then use AJAX to send them to server.
