HttpHandlers / Modules :: Hanging Request.Form Collection Values / Request.Form Collection Is Readonly
Jun 20, 2010I'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 3 RepliesC# Get Custom Attribute Of Hidden From Request.Form
Jul 22, 2010I have some code which is rendering some custom attributes of Hidden Control (without runat=server).
Something like,
And I have a lot of these hidden elements on my form.
When I submit the form, I am looping through a set of ids, say 1200 to 1250, so I will read controls based on that, and also hidden with Request.Form["hdn "]
Now problem is, as we know we get value attribute from form when we do Request.Form["id"] for hidden, I want to read my custom attributes from hidden element. Is there any way? Note that, I can not touch the rendering part here.

Get Request.Form.Item By Matching Request.Form.Key?
Jul 6, 2010My 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")

View 4 RepliesHttpHandlers / Modules :: HttpModule That Alters Request.QueryString And Request.Form?
Jan 27, 2011We'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.
MVC :: Request.Params Request.Form Not Working In Internet Explorer 8?
Jun 29, 2010This 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
State Management :: Hidden Field Value In User Control / Make The Hidden Field Save Its Value?
Mar 23, 2011I have a custom user control which contains a asp hiddenfield object. The value of this hidden field is being set using javascript and I have verified that the value is being set properly. When a postback occurs the new value is not being saved and I cannot access it in my code.
I believe the problem is because the user control is not saved in viewstate and therefore the hidden field value is not saved accross postback. How can I make the hidden field save its value? I tried accessing it from the early page cycles and still no luck.

View 5 RepliesHow To Send A Collection And A Few Other Values In Json Form To A Webmethod?
Sep 28, 2010Upon clicking a button I need to send a collection and a few other variables to server in Json form.For each value in the collection the server code (C# ) wil update those other variables in the DB.
For example there is a ‘classnumber’ collection with values (First, Second, Third, ….),other variables (‘teacher_name’ and ‘subjectname’).For each value in the ‘classnumber’ collection I need to update the ‘teacher_name’ by searching for the ‘subject_name’ in the DB.So I need to pass the ‘classnumber’ collection,’teacher_name’,’subject_name’ values to server in json form. At the moment instead of sending the ‘classnumber’ collection I am sending ‘teacher_name’,’subject_name’,’classnumber’ as variables for each value in the collection ,which requires multiple requests made to the server.
Instead of these individual requests I am wondering if there is a way to send all the data at once to server in json form?
C# - How To Receive Input To A Hidden Textbox And Submit A Form
Sep 6, 2010I have an ASP.NET application designed for a Windows CE device that needs to take in information from a scanned barcode. The device sends the scanned data as string input with a crlf to whatever field has focus. I set up my page with a textbox that takes the input and posts back to look up the item.
Now, I'd like that box to not be visible to the user, but IE complains when I set focus to it if the field is "visibility: hidden" or "display: none". I've tried moving it off screen using absolute coordinates, but setting the focus scrolls the window to the new location.

C# - Accessing The Form Collection In An IHttpModule Causes Event Handler Not To Get Called On Default Page
Mar 18, 2011I've created a simple sample site to demonstrate the issue. In it, I have a Default.aspx Page that has a button on it:
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
<p><asp:Button OnClick="ButtonClick" Text="Button" runat="server" />
</p>
<asp:Label ID="output" runat="server" />
</asp:Content>
The code behind just sets the label text on the button click:
protected void ButtonClick(object sender, EventArgs e)
{
output.Text = "Button Click!!";
}
I then have an IHttpModule that gets called for every request:
[code].....
And now it's broken again! So to make a long story short, just by accessing the Form collection on the request in the IHttpModule, I somehow screw up the PostBack, and the event never gets fired.
