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.
Encrypt request.querystring and Descrpt request.querystring
View 1 RepliesWe'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 have a page create-quote.aspx. I want to open this page in different modes, depending on whether a querystring parameter is present or not.My question is at which event should I check, If I have a querystring parameter or not.I think, it should be preinit, what do you say.
View 3 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?
loop table depending on arraylist and load datagrid?
View 1 RepliesI have an asp.net gridview which represents some kind of reservation calendar. Each row represents a workplace and each column a day. The header value (date) is set by a method since the start of the time period shown by the gridview can be selected by the user. Since the date column can start at every day of the week I wanted to mark the weekend day columns with a special background. How to set this? (See .aspx code snippet below which is currently used for each column ().
Remark: ItemStyle-BackColor= '<%# %>' (dynamic) annotation isn't allowed in the <TemplateField> Tag and the actual date must be evaluated somehow from the header or another control.

So I've eagerly added the System.ComponentModel.DataAnnotations namespace to my model.
I've added things such as:
[Required] [DisplayName("First Name")]
public string first_name {get;set;}
I really like these attributes because they save me from having to write custom T4 and/or modify views heavily. This way, I can regenerate a view confident that it will add the display names I want, etc.
The problem comes in when I started building a DataGrid helper inspired by the one in ASP.NET MVC2 unleashed. In this helper, Stephen uses reflection to get at the column headings.
var value=typeOf(T).GetProperty(columnName).GetValue(item,null) ?? String.Empty;
Well, the trouble is I don't want to retrieve the property name. I want to retrieve the value for the DisplayName attribute.
My first attempt at this was to look inside the Attributes property of the PropertyInfo class. Unfortunately, none of the data annotations show up as an attribute.
Is there a way to retrieve the data annotations using reflection?
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.

I have capture the query string like this

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.

New users can register on my site by completing a basic form that has the create user wizard control with some additional information i am collecting using a CheckBox List. They can then log in to the site and and view "MypProfilePage.aspx" where I display the information with the CheckBoxList boxes already ticked based their selections which they can update. My problem is I have two levels of User and each one has a different registration form.
Registration Form A
Has 20 Items in the CheckBox List
Registration Form B
Has 10 items in the CheckBox List
On the Profile Page, I just want to show the CheckBox which is relevant to the Registration form A or B and with selections by the registered user. So therefore the User who registered on B will not be able to see the selections checkbox list for A.
Using ASP.NET MVC 2, I have a model for a view. The view has a dropdownlist of roles that is populated by the model and there is a list below that of checkboxes with a number of privileges. I want to show only specific privileges depending on the dropdownlist selected roleID and have it update the privileges everytime the dropdownlist changes. I know how to do this in web forms ASP.net with absolutely no problem but I cannot seem to figure out where to start in ASP.NET MVC. Can someone please advise me what I need to do or towards a tutorial that will show me what to do? I am a novice in MVC.
