I use querystring to retrieve parameters send from another form, let's say that you are and index.html and there is a link url to default.aspx like this
~/Default.aspx?var=hello

then and the Server code from Default.aspx to retrieve that value i have this.

string stTest = Request.QueryString["var"];
string stTest = Request.QueryString["var"];

now stTest is equal to "hello"
hope that help you

If your already resolved your issue, flag it as solved.

Its handy if you want to pass data to other pages, especially when you want it retained in the browser's history. If you POST search terms to google for example then you wouldn't have a list of all searches you performed in your browser history.

It comes from the days of ASP.

The "Request.QueryString" command is used to collect values in a form with method="get".

SimpleForm_1.asp

 Help with Code Tags

<form method="get" action="SimpleFormHandler_1.asp">
    <TEXTAREA NAME="location" COLS=33 ROWS=4></TEXTAREA>
    <input type='submit' value='Add Event'>
</form>
<form method="get" action="SimpleFormHandler_1.asp">
    <TEXTAREA NAME="location" COLS=33 ROWS=4></TEXTAREA>
    <input type='submit' value='Add Event'>
</form>

        'in SimpleForm_1.asp
        userLocation = Request.QueryString("location")
%>
<%@ Language=VBScript %>

<%
        Dim userLocation

        'location is the variable name as defined by "NAME="
        'in SimpleForm_1.asp
        userLocation = Request.QueryString("location")
%>

The "Request.Form" command is used to collect values in a form with method="post".

SimpleForm_2.asp

</form>
<form method="post" action="SimpleFormHandler_2.asp">
    <TEXTAREA NAME="location" COLS=33 ROWS=4></TEXTAREA>
    <input type='submit' value='Add Event'>
</form>

You'll probably find more info on it if you search for "ASP Request.QueryString" and "ASP Request.Form".

C#

string userLocation;
userLocation = Request.QueryString["location"];
string userLocation;
userLocation = Request.QueryString["location"];

userLocation = Request.Form["location"];
string userLocation;
userLocation = Request.Form["location"];

Ok, I will flag this thread then.
Ok, so I read all of your comments, and thanks for it

I'm gonna ask another question about this.

I need to get the id=123 in http://www.website.com/something.php?id=123, in my C# application. Whenever I press a new button on the website the C# app needs to get the new id, or
value etc etc. So would this then be the best solution to get it? Or could I better use something else..?

Thanks again,
Davey
