I'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.
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
I am creating a Payment request form that my customers are going to fill out and submit so they get paid I would classifi it as an invoice. Does any one have any examples or point me to a good place to read about creating this type of form and the database tables to support the application?
The form will basically have some fields they will fill in for the header then in the related stuf come charge amounts with there types aka partnumbers of sorts and also the ablity to put in there own types / aka partnumbers and there amounts. I wont be housing any amounts they will supply all the information of payment amounts and types.
i need to pass my Request.Form as a parameter, but first i have to add some key/value pairs to it. I get the exception that the Collection is readonly.
On a windows 2008 web server, I get the following error whenever posting a form containing html tags in textboxes:
A potentially dangerous Request.Form value was detected from the client (widget$txtText="
This is a common error and you fix it by either doing Page ValidateRequest = false or in the web.config with pages validaterequest = false. However, on this specific server, it completely ignores the validaterequest = false and throws this exception anyway. Has anyone seen this behavior before and know what else I can do to prevent this error? I've seen it in 2 web apps now on the same server, it's really weird.
I am building a DropDownList control dynamically. Constraining this discussion to within just the OnInit() method / state in the asp.net lifecycle, is the only way to see the dropdownlist's posted value to look at the Request.Form NameValueCollection? I m aware that the dropdownlist's viewstate is restored by the time OnLoad() is reached, but I need it's value before then (im pretty sure LoadViewState($object) is of no use?)
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 ..
Im dynamically generating an HTML Select Box, lets call it myselect. Im creating this select box based on some database values Im generating an HTML Select Box.. almost like a string that Im just spitting out to the page. So it's never a control in the codebehind, just part of a string thats rendered as HTML by the browser. If I submit my form, and in my codebehind I perform:
Dim myVal as String = Request.Form("myselect")
That code will give me the VALUE of the myselect select box. How can I refer to this control to cast it as a System.Web.UI.HtmlControls.HtmlSelect control? Request.Form seems to give me the value, but I want to reference the object itself..
I have a news list and when I click on every each news, it navigates to another page where I can see news details. What I need is I want to request every news title in news details page and show it in <title> section in <head> as the pages title. It means the <title> tag in news-details page must be dynamic and will change depending on every news articles title. But I don't know how to do this because the only parameter that will be sending from news-list page to news-details page is news-id and not news title.
I 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.
I have a few friends that I swap videos with and I am to design a meeting request form. The form should allow me to enter the contact details, the details of these friends I am swapping with and a suggested date and time to meet for the exchange. How do I go about this code.
and also i set the ValidateRequest="false" in the page directive's. and in code behind i also use HttpUtility.HtmlEncode . but again and again i am facing this error
"A potentially dangerous Request.Form value was detected from the client (ctl00$ContentPlaceHolder1$txtEmbed="<embed src='http://a...").".
These are not a kind of Sesison Or QueryString so what are them for ? I can get key names and values via Request.Form.Keys and Request.Form[i] but is it another kind of passing values something like session or querystring (post and get) so what is Keys ? Post or Get values? or another type of variable handling? can some friend explain this is useful for what ? what is the obvious difference Keys against QueryString and Session ? are they cookies or what ?
While adding the parameters to get/post request they need to be encoded in application/x-www-form-urlencoded form. So do we need to encode values each time ? Does JavaScript have any method for that ? What are the possible caches ?On server side when we read the values we do not decode them we directly say Request.Params["key"] and that returns value. Does that mean that they are automatically taken care when we read the values?
I have some code which is rendering some custom attributes of Hidden Control (without runat=server).
Something like,
<input type='hidden' id = 'hdn1221' name = 'hdn1221' OldValue = '12' OldMode = 'A' />
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<Id> "]
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.
I have one asp.net application, which has some problems while i am entering the special characters such as ": &#, " in the search box. If i enter this text in search box, i got the exception like this. A potentially dangerous Request.Form value was detected from the client (txtValue=": &#, ").
then i searched on the net, i got one general solution for this that to set the validaterequest to false. But no changes has been made on my application.
Simple mvc page with a few controls that includes a validation summary area.
Once the fields are completed there's a download button.
If I enter something invalid, as expected, my controller code updates the UI with the appropriate error. However, if I then correct the error, and then click the download button a file is downloaded, but the UI never gets updated - presumeably since there's no update on the view.
