How can I take more control in ASP.NET?

Question

I\'m trying to build a very, very simple \"micro-webapp\" which I suspect will be of interest to a few Stack Overflow\'rs if I ever get it done. I\'m hosting it on my C# in

You're definitely (IMHO) on the right track by not using runat="server" in your FORM tag. This just means you'll need to extract values from the Request.QueryString directly, though, as in this example:

In the .aspx page itself:

<%@ Page Language="C#" AutoEventWireup="true" 
     CodeFile="FormPage.aspx.cs" Inherits="FormPage" %>




  


    
      
Results:
      
      

    
    
Parameters
    

    
      Parameter 1:
    
    
      Parameter 2:
    
    
    

and in the code-behind:

using System;

public partial class FormPage : System.Web.UI.Page {

        private string param1;
        private string param2;

        protected void Page_Load(object sender, EventArgs e) {

            param1 = Request.QueryString["param1"];
            param2 = Request.QueryString["param2"];

            string result = GetResult(param1, param2);
            ResultsPanel.Visible = (!String.IsNullOrEmpty(result));

            Param1ValueLiteral.Text = Server.HtmlEncode(param1);
            Param2ValueLiteral.Text = Server.HtmlEncode(param2);
            ResultLiteral.Text = Server.HtmlEncode(result);
        }

        // Do something with parameters and return some result.
        private string GetResult(string param1, string param2) {
            if (String.IsNullOrEmpty(param1) && String.IsNullOrEmpty(param2)) return(String.Empty);
            return (String.Format("You supplied {0} and {1}", param1, param2));
        }
    }

The trick here is that we're using ASP.NET Literals inside the value="" attributes of the text inputs, so the text-boxes themselves don't have to runat="server". The results are then wrapped inside an ASP:Panel, and the Visible property set on page load depending whether you want to display any results or not.
