how to find values from hidden query string

Hi,

This is not a hidden QueryString, this is a HTTP Post (http://en.wikipedia.org/wiki/HTTP_POST[^]).

To access the Post data (from non-ASP.NET Postbacks!), you can use the Request.Form object.

Example:
If you have a HTML form which posts the following:

value1=hello&value2=world

then you can access the two variables by using this syntax:

string value1 = Request.Form["value1"];
string value2 = Request.Form["value2"];

If you have a form which was created using ASP.NET (using for example a <asp:button runat="server" />, you should ALWAYS use the ASP.NET eventhandling and you should never access the Request.Form directly!
Here is a example about how a ASP.NET postback should work: http://www.xefteri.com/articles/show.cfm?id=18[^]


Hope this helps.

Best regards and happy coding,
Chris
