C# - Why Request.QueryString Replace + With Empty Char In Some Cases
Jul 28, 2010
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?
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'm a new developer...i have been given a project to generate a user name of 6 chars. the user name has 1st 2 char the 1st 2 letters of the name and remaining 4 char as any random numbers. alone with that i have to send a random password with it..
I have string. There are no items to show in this view of the "Personal Documents" then assign to string str variable string str ="There are no items to show in this view of the "Personal Documents" library" Now planning to replace "" and make it to actual string to str object. I tried below, but did not worked
str = str.Replace(@"",string.Empty);
I want str value should be string str ="There are no items to show in this view of the "Personal Documents" library" I need to find this string in another string. While searching into that string. I couldn't found because str contains "".
I've got a request to redesign the web application to allow support for up to 3 users (before there was data only for one people on page). Since I don't want to build entire page again I wonder how is possible to replace value which is for example:
[Code]....
with value retrieved from querystring?
Users are displayed on page in row: querystring value ID(for example 123), QS value ID2(for example 231), QS value ID3(for example 343).
Users are all stored in one row of the same table. If second user is selected then value of his/her should be taken as value of ID.
I'm using quite a lot <%# Eval ("ID")%> on my page and I don't want to replace it with some object but just overwrite it's value according to querystrings values.
I hope this doesn't sound too complicated as the real problem is fairly easy but don't have ideas how to deal with it. I've thought I can put to replace the value retrieved from SP but I can only change parameters. And ID is not select parameter.
If I have JSON like this and pass it to the engine I am using to create a PDF file, the word "null" appears on the PDF. This isn't really my example, but I googled "json replace null empty string" and this was a hit, which is a good representation of my data, also:
We use a rendering engine that creates a PDF from a fixed template and variable data in the form of a json string. But our customers don't want to read that the id is "null", they want to read that the id is blank. In my C# program, the json is just a string, so I can easily do something like this:
jsonString = jsonString.Replace("null,", ",");but the issue is I can't replace null-comma with a comma, because then it's invalid json.
how to I make the rendering engine *and* my customer both happy?
I have a menu on my masterpage / defaultpage where I'm listing x categories. I would like to make a count of how many products there are in each category.
EX:
[Code]....
Obiously i need the specific categoryid, but how to I request that without having querystrings running since it is on the default page.
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.
(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 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:
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?
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.
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++ "....
