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 believe from reading various bits online that Application and Session data can be read from the page file, memory or crash dump. I'm not too concerned about that. My question is, can the values held be altered?Situation is licencing to a third party. They run the web app on their own servers. I have created a signed but unencrypted licence file that is readable but tamperproof. After checking that it hasn't been tampered with I want to read and save the licence information
into the Application object. Could someone with server administrator permissions change the licence information held in the Application object?

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 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.
[Code]....

I have a big form in which i have almost 10 update panels. some are having updatemode = conditional and others are always. Now by default when that page is opened i only show one dropdownlist.When that project dropdownlist (from which i populate the rest of the elements in my page) value is changed by user it takes long time to load the other elements. Also the other gridview which is also surrounded by update panel and mode in conditional takes long time to show edititemtemplate controls in edit mode.
I am unable to trace the reason behing delay. Few days ago it was working fine and fast but now it is slow.
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'
View 2 RepliesI have a few updatepanel in my asp.net webform . I'm doing some tests and I'm wondering how can i check what data send back to server in different situations ?
View 2 RepliesI am looping through all the posted data on my website and grabbing the values, this will then be used later on. The user is going to put 2 radio buttons on the page, one with a correct answer and one with an incorrect answer. I need to know how to see if a Radio Button is checked or not based on the posted data.
View 2 RepliesI have two Repeater controls, each hosted in a user control. Both user controls are contained in the same aspx page. Only one User Control is visible at any one time. The repeaters are comprised of checkboxes, and text boxes for user input.
The aspx page is configured with an Ajax ScriptManager; and contains several Ajax UpdatePanels. These UpdatePanels result in partial page post backs when text is changed in a textbox control in controls on the aspx page (this is not the behaviour for the Repeaters in the User Controls). Through use of several AsyncPostBackTriggers, various controls contained in the other UpdatePanels on the page have their content refreshed in response to the partial page post backs they are configured be notified about.
Depending on a radio button group selection, I set the visible property to true or false - as appropriate for the User control containing a repeater control. The Repeater control is then populated with data using databinding. All of this works.
However, when the Submit button is clicked, the Repeater control contains no data.
Given that I am not dynamically adding the Controls containing the Repeater controls (but using Visible true / false). I would have thought that the State of the fields and the data in the visible control would be preserved during the post back.
The User Controls are contained within the UpdatePanel that contains the Submit Button.
I have explicitly Enabled View state without any effect.
Am I correct in assuming that I should not have to do any explicit handling of data changes the user makes (via client side script and manipulation of an Data Structure Representing the Repeater Data); and the View State should maintain the data I need to access on the server when submitted?
I do not believe that it is the User Control visible state changes that are causing the issue because when the page is initially loaded on of the User controls is populated with dummy rows (so it displays).
I am suspicious that because the visible state of the controls is changed during partial page post back, that the Page View State ends up with no knowledge of the User Control and therefore cannot track its data (or changes).
Our problem is the following:
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.
View 6 RepliesUsing Facebox with .NET (Web Forms) is painful--this primarily HTML site was designed by someone else. I may have IIS (7.5) issues as well. This Facebox pop-up is in a separate file, login.html, that is called from index.html:
$k('a[rel*=example_2]').facebox_1({
loading_image : '/images/loading.gif',
close_image : '/images/closelabel.gif'
});
and the link to open it
<a href="login.html" title="Log In" rel="example_2" id='login'>Log In </a>
The form to be submitted with username and password (login.html):
<form name="login" method="post" action="#" onsubmit="return false;">
and after it's validated (this is working), it posts to login.aspx (login.html):
[code]....
The form posts. I can debug it in Visual Studio in the Page_Load method of login.aspx. The last line of the Page_Load method is:
Response.Redirect("welcomepage.html");
But, the Facebox pop-up remains. Firebug shows the post, It hits the Page_Load method of login.aspx, and the Facebox pop-up doesn't go anywhere. BUT, Firebug shows welcomepage.html rendered twice in the Response tab of the XHR (huh? why XHR?) request. I thought $.post did a regular postback. And why isn't my browser actually redirecting.
Attempted Fix
If I change the form in login.html to action='login.aspx', I get a 405.0 error method not allowed (but, it's trying to post to index.html, HUH?). And I can't figure out how to fix this in IIS 7.5 on Windows 7. I get this error in Visual Studio and when deploying locally to IIS. I had read it may have to do with script mapping, handlers, or the fact that I'm posting from an but I can't find a sufficient fix.
I am trying out ASP.NET MVC2. I have a controller called SearchController and a view folder called Search containing Search.aspx. In my controller I have:
[code]....
In my view I have:
<form action="Search/Post" method="post">
<label><% Response.Write(Model.Title); %></label>
<input type="Submit" Value="First" Name="submitButton"/>
</form>
It works fine the first time I click the button, and the browser shows a url of [URL]. However, when I click the button a second time the browser url changes to [URL] and I get a 404. What am I doing wrong?
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???
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:
<form id="postForm" method="post" action="target.aspx">
<input type="hidden" id="id" />
</form>
I submit the form from javascript with jquery:
$("#id").val(id);
$("#postForm").submit();
Is there a way access the value of the hidden field on the target page?
I have a single model type to wrap up various models I want to use in my view:
public class QuestionViewData {
public Question Question { get; set; }
public IList<Answer> Answers { get; set; }
}
Now, in my question view I pull the data from the Question object - that's fine. Secondly I iterate through all Answer objects and pass them to a partial view:
<% foreach(Answer item in Model.Answers) { %>
<% Html.RenderPartial("ShowAnswer", item); %>
<% } %>
For each answer (in the partial view) I have some action buttons (like ratings). I'm using separate form POST's with hidden fields for every button. The problem is that I can't post the whole QuestionViewData model to my action method cause I only have the Answer object as model in the partial view. However, I need to return the complete question view from that action that takes QuestionViewData as model.
I am trying to simulate a POST to a form on an external server that does not require any authentication, and capture a sting containing the resulting page. This is what the form looks like:

<INPUT type="hidden" name="JSPName" value="GIN">
Field1:
<INPUT type="text" name="Field1" size="30"
maxlength="60" class="txtNormal" value="">
</FORM>
This is what my code looks like:
ASCIIEncoding encoding = new ASCIIEncoding();
string postData = "Field1=VALUE1&JSPName=GIN";
byte[] data = encoding.GetBytes(postData);
// Prepare web request...
HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create("https://XXX/controller");
myRequest.Method = "POST";
myRequest.ContentType = "text/html";
myRequest.ContentLength = data.Length;
Stream newStream = myRequest.GetRequestStream();
// Send the data.
newStream.Write(data, 0, data.Length);
StreamReader reader = new StreamReader(newStream);
string text = reader.ReadToEnd();
MessageBox.Show(text);
newStream.Close();
Currently, the code returns "Stream was not readable".
I don't know how to retrieve a DropDownListFor value on form post and how to validate it.
This is my scenario:
HTML markup:
[Code]....
Model:
[Code]....
I'm not able to validate this dorpdown and when I test if the Model is valid I have to re-fill the Location property
[Code]....
otherwise I get an "object reference not set" error on post-back.
