I have an aspx page where I want to post values to a new page and then redirect to that new page. I don't get any errors and the redirection occurs but the AllKeys collection is always empty.
Here's an example of my code:

I am using Asp.net and requirement specifies i use html input to post files to server rather than asp:fileupload.[ Reason : Add more html input file controls similar to CPanel file manager.(i.e) clicking on link adds another file input from which user can select another file*.But when ever i post back Request Files collection is always empty.*
HTML FORM:
<form method="post" enctype="multipart/form-data" action="documents.aspx">
<div>
<input type="file" name="attachment" id="attachment" onchange="validate(this)" />
<span class="none">Filename should be within (1-25) letters long. Can Contain only letters
& numbers</span>
<div id="moreUploads">
</div>
<div id="moreUploadsLink" style="display: none;">
<a href="javascript:addFileInput();">Attach another File</a></div>
<input type="submit" id="btnSubmit" />
</div>
</form>
Javascript:
var upload_number = 2;function addFileInput() {
try {
var fileUpload = document.getElementById("attachment");
var elemSpan = nextElement(fileUpload).cloneNode(true);
var elemDiv = document.getElementById("moreUploads");
var d = document.createElement("div");
var file = document.createElement("input");
file.setAttribute("type", "file");
file.setAttribute("id", "attachment" + upload_number);
file.setAttribute("onchange", "validate(this)");
d.appendChild(file);
d.appendChild(elemSpan);
elemDiv.appendChild(d);
upload_number++;
} catch (err) { alert(err);}}
the validate(this) is a function that validates file types on client.When validation succeeds then the link to add more file inputs is enabled. Could someone throw somelight on this.
I have checkboxes that I have created using Literal now on postback I get the checkboxes which are checked in the Request.form.Allkeys. However I don't know how to read those values how can I use them? how can I count how many values are in there and how can I find some values in there example I want to find if the request.forum.allkey contain forumaName0 ..
View 1 RepliesI'm using HttpModule to capture requests to the web server. Before processing the page I'd like to check the values contained in some keys of the Request.Form collection and according to some logic change if necessary. I'd like to do this when BeginRequest event is fired. The problem is that the Request.Form collection is readonly.
View 4 RepliesI'm using a custom ashx handler to handle a file upload. When run locally, the file uploads fine.When I use the same setup on the web server I get a "Index out of range" error.In firebug I see the binary contents of the file in the post data and the file name is also passed in the query string.Any one seen this before?I`m sure its something minor, but its driving me up the wall.

Request.Form collection does not contain Form hidden field value.
Using 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 $.post did a regular postback. And why isn't my browser actually redirecting.
Attempted Fix
If I change the form in login.html to action='login.aspx', I get a 405.0 error method not allowed (but, it's trying to post to index.html, HUH?). And I can't figure out how to fix this in IIS 7.5 on Windows 7. I get this error in Visual Studio and when deploying locally to IIS. I had read it may have to do with script mapping, handlers, or the fact that I'm posting from an but I can't find a sufficient fix.
Currently whenever I need to send a request to a payment-gateway, for example, I redirect my page to another page on my website which has a form with several hidden fields. I then pre-populate the values of these fields server-side, and specify in the body tag something like 'onload="form.submit();"'
However, I'm wondering, rather than redirecting to this page, is there anyway that all this data can be collected and POSTed to the payment-gateway server-side?This will cut out the need to redirect the user to this blank page, and make everything a bit more tidy.
I know that if I have set a cookie on a previous request, it will show up in my Request.Cookies collection. I want to update my existing Cookie. Are the cookies from my Request.Cookies collection already copied to my Response.Cookies collection? Do I need to add a new cookie with the same key using Response.Cookies.Add(), or do I need to use Response.Cookies.Set()?
View 1 RepliesIs there a way to force a non-secure form post to be secure? I understand there are ways to automatically resolve an http URL as an https URL but with form posts, is this type of redirection too late? Will the posted data have already gone through the wire as plain text?
View 3 RepliesMy Request.Form keys are all prefixed with ctl00$container name$ and then the key I want.
How can I get the regular key name working?
Visual example from the immediate window:
I want to use:
? request.Form.Item("stationIdea")
but it won't work because the key is:
ctl00$content_innovation_body$stationIdea
as retrieved by
? request.Form.Keys("4")
so only this works:
? request.Form("ctl00$content_innovation_body$stationIdea")
I have an ASP.NET file upload control which sits as part of a form. The file upload control is on the content page while the form definition is on a master page across the site. I've added multipart/form-enc to the form on the master page.I'm using jQuery to submit the form as I show a dialog box from jQuery UI.When I post, no file is returned to the server. The file upload control has no file and HttpFileCollection is empty.
View 3 RepliesI have an ASP page with the following repeater:

Why is the collection empty, when there are controls drawn on the screen?
(BTW: I tried adding/removing the EnableViewState="true" tag)
I have a MyLinkButton : LinkButton.
In any event I override I don't have any attributes in my "base.Attributes or this.Attributes" collection. How's that possible? The rendered output clearly shows an id and an href attribute.
I'm trying to get rid of the href part and put in my own. Unfortunately Attributes.Remove("href") won't work.. because there's no such attribute. Or any attribute for that matter.
Given the following InsertItemTemplate (simplified) I'm not getting anything back in the event object's Values collection.

I'm binding the listview to a collection attached to my nHibernate model object (SearchObject.SearchItems). This collection doesn't have insert or update handling like an object datasource would, so I want to handle the insert/update events manually. Is there a way to get these values to come through automatically, or do I have to manually grab each value from its control when I handle this event?
We're trying to implement functionality that intercepts, inspects, and alters if needed data in the Request.QueryString and Request.Form collections.
Since Request.QueryString and Request.Form are readonly, is it possible to use a HttpModule to do this without Reflection or Response.Redirect?
We're thinking that we can construct a new HttpRequest, and replace the original one. Would there be any implications in doing this?
I know mocking this object is impossible without using HttpRequestWrapper, but wasn't sure whether ASP.NET sets other things beyond the constructor.
This is a input
<input type="image" src="<%=Url.Content("~/images/shopping-cart.jpg")%>" alt="shopping cart" id="btnshoppingCart" name="btnshoppingCart" value="shoppingCart" />
when i browse the page with firefox and click on the input Request.Params["btnshoppingCart"] != null or Request.Form["btnshoppingCart"] != null is statisfied.
When i browse the same page with internet explorer 8 and click on the same input Request.Params["btnshoppingCart"] != null or Request.Form["btnshoppingCart"] != null is not satisfied. When i used the watch i saw that there is no key by the name of "btnshoppingCart" in either Request.Form or Request.Params if input is clicked from internet explorer. However when it is clicked from firefox there is value "shoppingCart" inside Request.Form and Request.Params against "btnshoppingCart" key. One more strange thing that i observed was that are two keys "btnshoppingCart.x" and "btnshoppingCart.y" inside both Request.Form and Request.Params whenver clicking is done from both internet explorer and firefox. This is happening against all inputs of type image irrespective if the input is present inside a html form or not. Forms are created like this
<% using (Html.BeginForm("Action", "Controller", FormMethod.Post)){%>
The version of internet explorer is 8.0 and firefox is 3.6.6
In an MVC view, I'm looking for a way to determine if a parent entity's collection of child entities is empty, so I can decide if I need to call a RenderPartial() or not.
For a one-to-one I've been using the following:
<% if (Model.Book.GenreReference.EntityKey != null) %>
{.....}
but I'm unsure how to do it in a one-to-many scenario, or if it can even be done without the use of Include() or Load().
I have an ASP .Net TreeView control that I am dynamically adding tree nodes to from my codebehind on Page_PreRender. The TreeView is populated nicely and the appropriate checkboxes are where they are expected to be. For each of these nodes the SelectAction=TreeNodeSelectAction.None. However, when accessing the TreeView CheckedNodes() collection in my codebehind after selecting a few nodes (checkboxes are selected) and clicking a submit button to post back to the server in the button click event, my CheckedNodes.count() = 0. I can not figure out why my CheckedNodes collection in the codebehind does not contain the nodes that I have checked from the GUI.
