title: Ajaxtoolkit TextboxWatermarkExtender: How to change the text from Javascript
body: <p>I think thaAjaxControlToolkitTextBoxWrapperThis use to work, but I think that upgrading to te latest version of teh Toolkit (4 something) broke it:</p>
  
  <pre><code>    var txtExpireYear = document.getElementById("ctl00_phPageContent_dtmPassportExpirationDate_txtYear");
    txtExpireYear.AjaxControlToolkitTextBoxWrapper.set_Value(dtmDateOfExpire.getFullYear()); 
  </code></pre>
  
  <p>I now get the error:</p>
  
  <pre><code>Microsoft JScript runtime error: 'AjaxControlToolkitTextBoxWrapper' is null or not an object
  </code></pre>
  
  <p>Executing this: </p>
  
  <p>txtExpireYear.innerText="value1"
  txtExpireYear.value="value2"</p>
  
  <p>results in the watermark text being changed, not the textbox's text.</p>
