C# - Cannot Pass A Input From Text Box To A Query String And Then Keep The String In This Box?

May 28, 2010

I have a simple ASP.net page:

<form id="form1" runat="server">
<p><asp:TextBox id="input_box" runat="server"></asp:TextBox>
<asp:Button Text="OK" runat="server" OnClick="run" /></p>

I want to send input from input_box to a query string, and then keep this input in the input_box when the page reloads.

That's the code behind page:

protected void Page_Load(object sender, EventArgs e)
input_box.Text = Request.QueryString["input"];
protected void run(object sender, EventArgs e)
string url = string.Format("?input={0}", input_box.Text);
Response.Redirect(Request.Url.AbsolutePath + url);

Problem is that when query string is not empty, string from input_box cannot be passed to query string. How to correct it?

Jan 19, 2010

In IE 7, I can right click on my page and select properties and (usually) see the query string that was passed to that page.

How do I see this in FireFox? I am having a bug where I should be passing consecutive numbers in the query string, such as deal_ik=1,2,3,4,5 etc but 5 is missing. So I want to examine the query string that is actually getting passed.

Include Dynamic URL In My URL Without Using Query String?

Jan 18, 2010

ASP.NET 3.5, IIS7,In my Global.asax's Application_BeginRequest, I need to extract from the request's URL an entirely seperate URL that's been embedded in it without using query string.

The solution I came up with was to hex-encode the entire target URL as if it were a directory, as follows:


This fails for IIS7, whose ASP.NET implementation won't tolerate a URL path greater than 260 characters.My code controls how the request URL gets generated, and how it might embed the target URL in there, but it doesn't have any control over that target URL value (they're third-party URLs).How better could I embed this target URL in my request URL?

Good Way To Parse Query String?

Jan 10, 2011

I have a String that contains the following: ?workarea=London+&+Home+Counties+Ltd&sub=fs&&&FASh*5which resembles a URI query string. What is the best way to parse the elements of this string (workarea and sub) without messing about with string manipulation?If I use HttpUtility.ParseQueryString is gets stuck as both elements include &. However if I encode the whole thing first I lose the seperations of the elements. Ideally the output would be:workarea = London & Home Counties Ltdsub = fs&&&FASh*5
