I've got 2 textboxes and a button. One is for the user to input his text and the other is to scramble the letters and output them. Once the user writes his text in the first text box, how do I assign the value of the first textbox on the buttons click to a string that I'll output later?

I guess you need something like the below code :-
Design page code :-

C#

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

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <table style="width: 100%;">
            <tr>
                <td><asp:label id="Label1" runat="server" text="Enter First Input" xmlns:asp="#unknown"></asp:label></td>
                <td> <asp:textbox id="TextBox1" runat="server" xmlns:asp="#unknown"></asp:textbox></td>
            </tr>
            <tr>
                <td><asp:label id="Label2" runat="server" text="Enter Second Input" xmlns:asp="#unknown"></asp:label></td>
                <td> <asp:textbox id="TextBox2" runat="server" xmlns:asp="#unknown"></asp:textbox></td>
            </tr>
            <tr>
                <td><asp:button id="Button1" runat="server" text="Button" onclick="Button1_Click" xmlns:asp="#unknown" /></td>
                <td> </td> 
            </tr>
        </table>
    </div>
    </form>
</body>
</html>

Code behind page code =

C#

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
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        TextBox2.Text = scramble(TextBox1.Text);
    }

    private string scramble(string inputString)
    {
        string output = inputString;

        /* your logic to scramble the input string */

        return output;
    }
}

Hope it will help you.

1.In code behind page find the buttonclick event(method)
2.Find the ID of the textbox,or give it an id like id ="txt1".
3.Inside the button click event :
string input= (give your text box id here) txt1.Text;
ScrambleWord(input)
4.Find the ID of the second textbox or give it an id like id="text2".
text2.Text=ScrambleWord(input);

public string ScrambleWord(string word)
{ char[] chars = new char[word.Length];
Random rand = new Random(10000);
int index = 0;
while (word.Length > 0)
{
int next = rand.Next(0, word.Length - 1);
chars[index] = word[next];
word = word.Substring(0, next) + word.Substring(next + 1);
++index;
} return new String(chars);
}
