ADO.NET and have a query about reading a unique data value from a table.
PHP Code:
<%@ Page Title="" Language="C#" MasterPageFile="~/Dorknozzle.master" AutoEventWireup="true" CodeFile="BlogEntry.aspx.cs" Inherits="BlogEntry" %>
<%@ Import Namespace = "System.Data.SqlClient" %>
[code]...
Is it possible to write something like:
<%# Request.QueryString("id") %>
in an .aspx page? generally, I fetch these values from codebehind, but now I need to do in here, like:
<asp:XmlDataSource ID="dsNewsitem" DataFile="~/App_Data/news.xml" runat="server" XPath='/news/item[id = "<%# Request.QueryString("id") %>"]' />
if i have url in string format like
"redirect.aspx?id=1 &name=n1 &add=abc"
is there sum in built function in asp.net to retrieve querystring values from this considering this as url.
I have two Drop Down Lists (DDL), DDL1 & DDL2 respectively. DDL1 gets populated with "State" from a backend database where as DD2 gets populated with TWO fields "LATA" & "LATA Name" concatenated together. Here are the codes for the DDL2 :
[Code]....
The code behind the Submit button is using Querystring and directing to the next page:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Response.Redirect(String.Format("Option1_result.aspx?ddl2={0}& ddl3={1}", HttpUtility.UrlEncode(DropDownList2.SelectedValue),
HttpUtility.UrlEncode(DropDownList3.SelectedValue)))
End Sub
My problem is: How to retrieve data from a Querystring which contains data from two concatenated SQL columns? I want to selectively retrieve only the first three digits in the ddl2 Querystring which will give me the LATA number.
In the following code, I need to modify the Handler so that the records or results that display are based on a QueryString value. Currently all of the records in the table display on the page but I want records to display based on the passing a querystring value based on the field, id. I have tried to alter the code without much success.
Public Class FileVB : Implements IHttpHandler
Public Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest
Dim id As Integer = Integer.Parse(context.Request.QueryString("id"))
Dim bytes As Byte()
Dim contentType As String
Dim strConnString As String = ConfigurationManager.ConnectionStrings("fitnesConnectionString").ConnectionString
Dim name As String
Using con As New SqlConnection(strConnString)
Using cmd As New SqlCommand()

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'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?

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??
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.
