I've got a web page that will have information passed to it, and after doing some checking it will log the user that was passed to into a secure site. Currently I've got the code below working, it actually posts the respected page and logs me in. Howevever, the problem arises after it the login page appears. Instead of the url in the address bar of explorer showing the web address of the page I'm on it shows the web address of page that sent me to the log in. Is there any way using this code (or another set of code) that will allow me to do this? This is part of a single sign on project, and most of this is pretty new to me.
Dim postData =
String.Format("my post data")
Dim data
As String = postData
Dim uri
As New
Uri("my web address")
If uri.Scheme = uri.UriSchemeHttp
Then
Dim request
As HttpWebRequest =
HttpWebRequest.Create(uri)
request.Method =
WebRequestMethods.Http.Post
request.ContentLength = data.Length
request.ContentType =
"application/x-www-form-urlencoded"
Dim writer
As New
StreamWriter(request.GetRequestStream)
writer.Write(data)
writer.Close()
Dim oResponse
As HttpWebResponse = request.GetResponse()
Dim reader
As New
StreamReader(oResponse.GetResponseStream())
Dim tmp
As String = reader.ReadToEnd()
oResponse.Close()
Response.Write(tmp)
Exit Sub
End
If
Update: Ok, it seems as though the method above is "scraping" the response from the web page and placing it on my page. This isn't what
I want. I want to post the data and actually go to that page.
I need to post data from my asp.net page to a non-asp.net page that is offsite. How can I do that without redirecting to that page? IE: not using a button's PostBackUrl property.
I have an ASP.Net form that gathers some data, validates it and then submits it to PayPal. PayPal expects a form control named AMOUNT in the POST. However, since I am using webserver controls and validating that data, it comes across as ctl00$ContentPlaceHolder_Body$AMOUNT.What is the best way to change this over so that PayPal will be happy and the data can get properly posted? I could change them to <input> controls and not validate, but that isn't what I really want to do. I could take the input and then programatically create the data and then post it to the PayPal URL, but I'm not sure how to do that. These are just some of the things I have considered doing.
I have an app which has a form that used to use AutoPostBack rigged controls (dropdowns, radiobuttons etc.) in an updatepanel, and I used to set session values on each postback. I posted the form using PostBackUrl to an external page, using a bit of javascript OnClientClick to copy my data into meaningfully named hidden fields.
Now, I've had to rewrite the AutoPostBack-ing controls so that all the cascading dropdown work and date calculation etc. is done in JavaScript, and not in C# - no more postbacks, no more updatepanel.
This means I've lost the ability to set my session values on postback. Can anyone think of a solution for setting these before I post my form? I need to set the session variables, plus post (querystrings are not an option) to the external page with the values from my form - and actually send the user to the external page, too.
I have a repeater with a nested LinkButton that passes record's unique identifier (ADRTYPECODE) to the same page.I would like to change its behavior to pass the same argument to a different aspx page.How do I make that page respond to an event fired by this button?
Some say it is not a bug it is default in asp.net. but for me it is a bug in logic. When you say refresh it should be reload the component that you are refreshing. But in asp.net i notice that they recalling all activity and viewstate like event and data that are triggered in the previous postback. My opinion it is a redo not refresh. this is only my observation on the issue dont hate me on this microsoft fan.
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 need to send a simple variable value from my WPF app to an aspx page. The page runs under an anonymous web site. What are the best practices to post a single value and ead it out on the other side (aspx)?
i am trying to grab data from here : http://mediaforest.biz/mobile/nowplaying.aspx in the page you select a station and post it then you get new page with data. but i cant grab it, i get the same page again.
I have a page that I am adding user controls to the bottom of the controls each postback. The User Control has a textbox in it and the focus needs to be on this newly created control textbox each time. It all works almost perfectly however when there are too many controls to fit on the page, because I set the focus to the textbox the bottom of the page is set to the textbox that has focus not the very bottom of the page. I have a submit button below this which ends up below the page limit. How can I set focus to a textbox but still scroll to the every bottom of the page to show the submit button.
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 have a hidden value field on a page. On submit I post to a different page. On the page I've posted to I do a Request.Form but I do not get the value just a null value. This is the initial page
The javascript ViewCancellation function is set to a hyperlink in the code behind. The function will have a value like this,<a href="#" onclick=" View Cancellation(54666);return false;">cancel</a>.
I'm using a form to POST credentials to a page. I'm able to POST my credentials to a page, but I'm stuck on trying to load that page that I POSTed my credentials to. In other words, the POST works, but the page doesn't then reload...here's a code snippet of what I'm running. I suspect I'm missing something and my knowledge of classes is limited so maybe it's a particular class I need to use.
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.
I have 2 forms on one page. 1 search form which only contains a text field and a submit button and 1 registration form which has a few required fields. The search form need to post data to search.aspx.
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???
