title: jQuery DatePicker - DatePicker Is Not A Function
body: <p>I am always getting the error datepicker is not a function". If I view source in Firebug, I can click on all the jQuery script links and they are all valid. I can even do a search in the main .js file for the datepicker function and see it there.</p>
  
  <p>So the function seems to be there, the rest of jQuery seems to be working - what could I be doing wrong?</p>
  
  <p>It is an ASP.NET environment however I'm using a standard HTML control, so it's not a naming issue.</p>
  
  <p>Doing my brain in. Any suggestions welcome.</p>
  
  <p><strong>Update 2</strong></p>
  
  <p>Prompted by a comment from Drew, the input control I want to be my date picker is in an update panel. Is there a workaround for this scenario?</p>
