title: How to edit a control content in an array inside of a list
body: <p>I got the following:</p>
  
  <pre><code>List&lt;TextBox[]&gt; ListMonths = new List&lt;TextBox[]&gt;();
  </code></pre>
  
  <p>I use it for store the same textboxes for each month, I fill it like this</p>
  
  <pre><code>for (int i = 0; i &lt;= 11; i++)
  {
      ......
  
      TextBox[] TBaux = new TextBox[18];
      for (int o = 0; o &lt;= 17; o++)
      {
          TBaux[o] = (TextBox)element.FindName("TB" + o + i);
      }
      ListMonths.Add(TBaux);
  }
  </code></pre>
  
  <p>So that way I got the textboxes for each month in <code>ListMonths</code>.</p>
  
  <p>How can I modify the Text property of one of the textbox (for instance <code>textbox[2]</code>) that is stored in one of the month lists (for instance <code>ListMonths[1]</code>)?</p>
