I have a page which will have these urls,
http://localhost:1218/Order-AUG17/Forms/Order.aspx?ContactName=HajaMubeen and
http://localhost:1218/Order-AUG17/Forms/Order.aspx
and in my page load i have checked this,
if (Request.QueryString["ContactName"] != "")
//My logic
else
//My logic
But this if condition fails for both the urls.
I need to check if any rows are returned in a QueryString here's what I have so far.not sure what code to put to see if the row count is greater than 1
private void BindDataToGrid()
{
//MessageBoardEntities3 is ThemeableAttribute connection string name
int TID = Convert.ToInt32(Request.QueryString["ThreadID"].ToString()); // if Post ID is int
var context = new MessageBoardEntities3();
gvPosts.DataSource = from p in context.Posts
where p.ThreadID == TID
select new { p.Post1, p.PostID };
gvPosts.DataBind();
lblNoPosts.Text = "No posts found for this thread.";
}
Encrypt request.querystring and Descrpt request.querystring
View 1 RepliesThe following code works well as long as I pass a querystring value to the datalist.
Private Sub BindGrid()
Dim id As Integer = Integer.Parse(Context.Request.QueryString("id"))
Dim strConnString As String = ConfigurationManager.ConnectionStrings("Conn").ConnectionString
Using con As New SqlConnection(strConnString)
Using cmd As New SqlCommand()
cmd.CommandText = "select Id, Name from tblFiles where Id=@Id"
[Code] ......
However, the page errors with the message "Value cannot be null." if I don't pass a value. I know that DataList does not have an EmptyItem Property like a Gridview control. I do not want the page to error if I don't pass a value. Need info to deal with empty values in a datalist.
Most websites have pointed me to this code to use:
<FooterTemplate>
<asp:Label ID="lblEmpty" Text="No Result" runat="server"
Visible='<%#boolean.parse(([b]list[/b].Items.Count=0).ToString())%>'>
</asp:Label>
</FooterTemplate>
The 'list' throws an error. The error is "Too few type arguments to 'System.COllections.Generic.List". I am not sure if the code is written in C# and that is what is causing the error. It seems that it should work but I can not figure out the 'list' error.
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.
I've done a lot of searching trying to figure this out: I am soon to develop an app using Personalized URLs in ASP .Net. Thankfully we are going to use the mysite.com/user1, mysite.com/user2 approach, as I can find plenty of info on making that happen using URL rewrites. However, in the post @ http://forums.asp.net/p/1259856/2842613.aspx#2842613 there is someone asking if there is a way to do something along the lines of user1.mysite.com, but dynamically. In the post there are answers that it can be done, but they are not very clear. I presented this my supervisor who then asked how does this work with DNS and I shrugged my shoulders and did the Scooby-Doo "I don't know" sound (rye-ron't-row)...
View 2 RepliesI'm intermittently seeing this exception being thrown:
A potentially dangerous Request.QueryString value detected
However when I look in the IIS logs I can see that the request that failed has no querystring logged against it.
How could this be? Are "dangerous" query strings being stripped from the log or something?

I have a page that I wish to pass an ID in a querystring to another page
eg
Response.Redirect("~/Account/Login.aspx?CertificateID="+ CertificateTextBox.Text);
but the value in the CertificateTextBox is in the format of Encoding.UTF8
so it can contains character like "ZnbiS69F2g22OeupHw+Xlg=="
When the receiving page gets the QueryString
CertificateTextBox.Text = Request.QueryString["CertificateID"];
the "+" and possible other querystring chars like "?" are stripped!!
so I end up with
Request.QueryString["CertificateID"];
returning
"ZnbiS69F2g22OeupHw Xlg=="
the "+" strinpped!
Is there a way to encode these chars so they are not striped by QuesryString()or do I have to use a session variable??
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.
Problem: string strTest = Request.Querystring["test"].ToString();
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 tried to do this:
Encoding enc = Encoding.GetEncoding(28591);
string strTest= Request.QueryString["test"];
strTest= HttpUtility.UrlDecode(strTest, enc);
Not working, since the Request.QueryString already has url-decoded the value using utf-8.
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.
View 2 Replieshow can i modified the querystring?
I have capture the query string like this
qs = Request.QueryString["flag"].ToString();
and then rebuilt the query string with modified values and response.redirect(url & qs) to it
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:
Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="WebForm2.aspx.cs" Inherits="WebApplication2.WebForm2" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
<script runat="server">
Request.Querystring("letter")
</script>
I know I'm passing the variable correctly because it works in a query further down the page, so I suspect I'm just not using Querystring right.
I have the following URL: /Login.aspx?ReturnUrl=Default.aspx#/mydesign
Request.QueryString["ReturnUrl"] only returns "Default.aspx".
Why doesn't it return "Default.aspx#/mydesign"?
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.
View 1 RepliesThe first time the user navigates to my page there will be no query string in the url.
The page will display them 10 posts, and at the bottom there will be a 'next page' button that will call the same page but this time pass the page a pageNumber in a query string and the next ten posts will be displayed.
how can I detect if there is a QueryString in the url so that only when the page is called by the 'next page' button and there is a QueryString is my code exicuted?
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++ "....
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.
