So I am trying to make the user input information that displays after clicking a button. I get the message but it doenst show the value input into the textbox. What am I missing?
here is my code

private string _eyecolor;
    public string Eyecolor
    {
        get { return _eyecolor; }
        set
        {
            if (!string.IsNullOrEmpty(value))
            {
                _eyecolor = value.Substring(0, 1).ToUpper() + value.Substring(1);
            }
            else
            {
                _eyecolor = value;
            }
        }
    }

    public string getEyeColor()
    {
        return "You have " + _eyecolor + "eyes!!";
    }

Here is my html code:

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

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
    <asp:Label runat="server" ID="lbl_1" AssociatedControlID="txtb1" Text="what is your eyes color?" Autopostback="true" />
    <asp:TextBox ID="txtb1" runat="server" />
    <asp:Button ID="btn_submit" Text="Submit" runat="server" OnClick="subSubmit" />
    <asp:Label runat="server" ID="lbl_output" />
    </div>
    </form>
</body>
</html>

and my codebehind:

 using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class _Default : System.Web.UI.Page
{
   Profile P = new Profile();
    protected void Page_Load(object sender, EventArgs e)
    {

    }
protected void  subSubmit(object sender, EventArgs e)
{
   lbl_output.Text=P.getMsg();
   lbl_output.Text+=P.getEyeColor();
}
}

    As Adil quite rightly pointed out, you need to grab the value from the <asp:TextBox> input and assign it to your property Eyecolor.

    Since getEyeColor is a function of the Profile object P in your posted code, try changing your Submit handler to the following:

    protected void subSubmit(object sender, EventArgs e)
{
    P.Eyecolor = txtb1.Text.Trim; //Add this to set the Eyecolor to user input.
    lbl_output.Text = P.getMsg();
    lbl_output.Text += P.getEyeColor();
}
