title: save and load data from .txt to the right texbox
body: <p>I want to use a <code>.txt</code> file instead of a XML and I want to keep using the <code>WriteAllLineS</code>/<code>WriteAllText</code> and <code>ReadAllLines</code>/<code>ReadAllText</code>. 
  I have two text boxes 1 &amp; 2 and next to them is a "save" and "load" button - one for each textbox.</p>
  
  <p>My code so far replicates the data from the first box into the second one. Here is the listing:</p>
  
  <pre><code>public partial class Form1 : Form
  {
   string fileName = "Cache/textBoxdata.txt";
  
      public Form1()
      {
          InitializeComponent();
      }
  private void load1_Click_1(object sender, EventArgs e)
      {  
        textBox1.Lines = File.ReadAllLines(fileName);
      }
  
   private void Save1_Click_1(object sender, EventArgs e)
      {
          File.WriteAllLines(fileName, textBox1.Lines);
       }
  
  private void load2_Click(object sender, EventArgs e)
      {
          textBox2.Lines = File.ReadAllLines(fileName); 
      }
  
  private void save2_Click(object sender, EventArgs e)
      {
          File.WriteAllLines(fileName, textBox2.Lines);
      }
  }
  </code></pre>
  
  <p>I want to be able to write text in the two text boxes, click the "save" button - this should write entered text to the file. Then, once I reopen the app click the "load" button, my data should be loaded from the file and appear in the text box.</p>
  
  <p>At the moment my first text box works. Second text box shows what I wrote in the first one - not the second one.</p>
