title: Restrict date in jquery datepicker based on another datepicker or textbox
body: <p>I have two text boxes with a datepicker hooked up to them. The text boxes are for start date and end date. The first datepicker is setup so that the user cannot choose a date before today, but can choose any date in the future.</p>
  
  <p>How can I setup the second datepicker so that it cannot choose a date before the date chosen in the first date picker? For example: If today is 12/11/10 and I choose 12/15/10 in the first datepicker, then the second date picker shouldn't be able to choose anything before 12/15/10.</p>
  
  <p>Heres what I have so far:</p>
  
  <pre><code>$("#txtStartDate").datepicker({ minDate: 0 });
  $("#txtEndDate").datepicker({});
  </code></pre>
