How do I use a comma separated list of values passed in a querystring in a SQL Query? For ex if the list passed is 1,2,3 I need my sql to be
Select * from temp where id in (1,2,3)
Since ID is an integer value this is throwing an error.
How can i use querystring for this-
Here in below code i have used querystring for sending imagename from this page to another page. Now i just want that with this imagename in also want to send span element's text with same querystring.How can i achieve this?
[Code]....
The 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.
I have a particular scenario and I would like to know how I can implement it in the most efficient way. I also have some queries related to this. The application is a AJAX 1.0-Enabled ASP.NET 2.0 Web application.
I have a link, which when clicked I need to show a pop-up div. The contents of the div will be displayed using a usercontrol. The usercontrol will display the contents based on a query string value.
I would like to know:
1. How can I implement this in the most effecient way. I don't want to use a separate page on which I will have the usercontrol and then display the page in the div.
2. Suppose I call a JS function ShowDiv() on the click of the link, to display the pop-up div. Say, I call the function this way ShowDiv('querystring'). Now how will I pass the value 'querystring' to my usercontrol.
I'm trying to send a string of XML as part of the query string. Normally I'd POST this XML but I'm sending it to a 3rd party system that I can't POST stuff to. So, as it goes, I need the 3rd party system to request the services of one of the pages in my system. (explanation: the 3rd party system produces PDFs of my web pages. I give it a URL to my page, and it PDF's that page. So, the XML file contains data that I need to generate the page) Anyway, I'm getting my query string as follows:
string data = Server.UrlEncode(xmlSnippet.ToString());
string sFullUrl = urlString + "?data=" + data;
I give the 3rd pary system this URL, and it calls my page.. except the request doesn't reach the page. It's failing into the Application_Error handler with this message:
"A potentially dangerous Request.QueryString value was detected from the client (data=[my XML data])" As I know the data I'm sending is safe, is there any way I can make this work?
i get the error that the server tag is not well formed when trying to create a dynamic hyperlink in my formview.?
<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl="~/sendes.aspx?id='<%# Eval("id") %>'">HyperLink</asp:HyperLink>
<br />
I'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?

how to get the url without querystring values in asp.net?
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?
string emailfield=txtEmail.Text.ToString();
string url = "http://localhost:3076/user/Authenticate-Users.aspx?email="+emailfield;

View 7 RepliesI 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??
I am trying to stop XSS attack so I am using html agility pack to make my whitelist and Microsoft Anti-Cross Site Scripting Library to deal with the rest.
Now I am looking at encoding all html hrefs. I get a big string of html code that can contain hrefs. Accours to MS Library they have an URL encode but if you encode the whole URl then it can't be used. So in the example they just encode the query string
UrlEncode Untrusted input is used in a URL (such as a value in a querystring) Click Here!
[URL]
So now my questions is how do I parse through a href and find the query string. Is it always just "?" then query string or can it have spaces and be written in different ways?
Edit
This urls will not be written by me but the users who will share them. So that's why I need a way to make sure I get all query strings and not just ones in valid format. If it can work invalid format I have to grab these ones too. Hackers won't care if it is valid format or not as long as it still does what they want.
