Web Forms :: Request.Querystring Isn't UrlDecoding?
Apr 15, 2010
Anyone else have the issue where you use javascript to stuff variables into the querystring and then when you call Request.Querystring, the value is still UrlEncoded?Example, I've used a javascript function to encode the string "dBskf6fm+ac=" into the UrlEncoded string "dBskf6fm%2Bac%3D".Usually when I set a breakpoint at the call to Request.Querystring(), the value displayed is the UrlDecoded string, but in this case, the value is still UrlEncoded.
(asp.net 2.0, c#) I have a page requesting a qyerystring looking like this ?test=b%E4st, %E4 is the url-encoded letter ä. I can't change how this looks and encodes since I have no access to the page doing the request.
If I then, for instance, just Response.Write(strTest) the character ä (%E4) is broken. Displayed as a question mark. I have in my web.config the requestEncoding and responseEncoding set to utf-8. That is the way I need to have it, and I can't change that.
I've looked around for a solutions for this and the issue seems to be iso-8859-1 vs utf-8 in the querystring and url-decoding. It seems the Request.Querystring automatically url-decodes the string using the default encoding, in my case utf-8. I need it to url-decode using iso-8859-1 instead. I can achieve this by altering the web.config, but as I said earlier this is not an option.
I have vendors who are passing customers to us via an encoded URL. The problem is that Request.QueryString["FieldName"] is returning NULL on some of them and I can't fiqure out why?
For Example, one vendor is sending : http://.....ViewListing.aspx%3FListingID%3D1187721%26Source%3D6"] which returns a NULL value when Request.QueryString["ListingID"] is used.
Using Server.UrlDecode(Request.RawUrl.ToString()), however, will decode itpProperly as /ViewListing.aspx?ListingID=1187721&Source=6
How do I get the Request object to properly retrieve the values?
When I pass some values like a++, c++, f+, as a parameter value in the url to an aspx page, I don't get the exact value in the aspx.cs page by Request.QueryString function. This problem is only with some special characters like +, _ , - etc.
Eg:
Consider this parameter string in the url : CourseName=c++&kval=0.7120968615801844&dval=1296217545373
Then when I trying to get the CourseName parameter value in the aspx.cs page using Request.QueryString ,
crseName = Request.QueryString["CourseName "];
I got the value of the variable crseName as " c " only instead of "c++ "....
Is there a way to grab the querystring from the original request or pull it from the ASPX ErrorPath?
We've updated 5 applications, and combined them into one. However, when someone requests and old URL such as [URL]I tried capturing the value from the querystring, but it does not seem to work since the aspxerrorpath is there (404 page).
in my page am having one dropdownlist,Textbox and Search Button.Dropdownlist consists of Problem id,Phone No,Email,CardNo. when i select any of the above and enters a related string in textbox and click on search button a gridview will appear with related details. Everything is fine. but my challange is to display this gridview in next page.. how itz possible. i think request.Querystring helps me.but i dnt know how to write dis.Here am Pasting my code. Aspx.cs
In aspx I have a querystring - www.mysite.com/enter.aspx?dest=#. When I click "enter" I go to main.aspx. I want to get this "?dest=#" in main.aspx with a request.querystring or something in javascript. I need to use the querystring in javascript in main.aspx for another action.
let me explain in detail - I have enter.aspx page that shall load with a querystring - www.mysite.com/enter.aspx?dest=#. Now when i click the Enter button on Enter.aspx page, it shall goto Main.aspx page. When main.aspx page loads i want to write small javascript in main.aspx that shall get the querystring from the previous enter.aspx page and give it an if condition. so if (request.querystring('dest=') > 0 window.open ('a1.jpg') this above code needs to be redesigned so it can work. how can i do this. i tried window.location.href.indexof('dest') , nothing happened.
I have url being passed to my page something like /default.apsx?id=123&user=justinIn my code I already have a request.querystring running to grab the id but I need also to grab the user how would i do this.
I'm passing a variable between pages and want to print the value of the variable on my page and don't particularly want to try to get into figuring out the codebehind stuff. I can't figure out the syntax. I'm trying:
My app has broken after upgrading to ASP.NET 2.0. The problem is that Request.QueryString is empty when the SelectedIndexChanged event of a IE Web Controls tab strip is fired. It worked perfectly in ASP.NET 1. I have the tab strip contained within my own UserControl.
I have completd my project, in that project i used Request.QueryString["id"], its working fine, in this project if change the "id" securities pages also opening now what can i do?
I want when I am search any another college then show my url

I have a problem that if I pass a string that contain + in a query string and try to read it , it get the same string but by replacing + with empty charFor example if i pass query like ../Page.aspx?data=sdf1+sdf then in page load I read data by data = Request.QueryString["data"] it will get as below data ="sdf1 sdf" I solve the problem by replacing any empty char with + .. But Is there any problem that cause that ? and Is my solution by replacing empty char with + is the best solution in all cases?
I have a web form, and it appears that when I add the AJAX control toolkit on my webform, my Request.QueryString is clearing out. Here is what happens:
1) User clicks next on form 3, and I load up form 4 (form 3 passes query string to form 4)
2) User clicks next on form 4, and form 4 checks the query string that was passed by 3, and it's emtpy
This only happened when I added AJAX functionality.
I have a control with a datagrid in it and I was wondering if depending on the value I get back from the a Request.QueryString if I could set the table name to that (that is the value being sent) and then have it build the columns?
I have about 3 different tables, and they have different amounts of columns, and of course with different names.
I have an ashx handler that was working fine in VS2008 but when I upgraded to VS2010 (haven't gone back to VS2008 to double check though) and when I try to grab the value from HttpContext.Request.Params["update"] I get the following error:
+ ex {"A potentially dangerous Request.QueryString value was detected from the client (update="<SETIProducts><Produ...")."} System.Exception {System.Web.HttpRequestValidationException}
I want to dynamically populate a link with the URI of the current request, but set one specific query string parameter. All other querystring paramaters (if there are any) should be left untouched. Eg, imagine I want to build a link back to the current page, but with the querystring parameter "valueOfInterest" always set to be "wibble" (I'm doing this from the code-behind of an aspx page, .Net 3.5 in C# FWIW).Eg, a request for either of these two:
Caveats: I'd like to avoid string manipulation if there's something more elegant in asp.net that is more robust. However if there isn't something more elegant, so be it. I've done (a little) homework: I found a blog post which suggested copying the request into a local HttpRequest object, but that still has a read-only collection for the querystring params. I've also had a look at using a URI object, but that doesn't seem to have a querystring
