title: Telerik asp.net mvc datepicker "Invalid argument" in Internet Explorer (IE) 8
body: <p>I am using Telerik asp.net mvc extensions. I have an issue that happens only in IE. I have IE 8. I don't have this issue in Firefox (3.6.3) or Chrome (4.1.249.1059)</p>
  
  <p>The problem happens when I want to pick a particular date by first clicking on the year on top and then the month. At that time, I get Invalid Argument error in jquery-1.4.2.min.js</p>
  
  <p>I am using VS2008 SP1 with ASP.NET MVC 2 RC2.</p>
  
  <p>I have tried this in a new asp.net mvc solution after "manually" modifiying it to become MVC 2 compliant and then doing all that telerik says on this page

  And finally using Datepicker in the Home/Index.aspx</p>
  
  <pre><code>    &lt;%= Html.Telerik().DatePicker()
      .Name("DatePicker")
  </code></pre>
  
  <p>%></p>
  
  <p><strong><em>Has anybody else run into this issue?</em></strong></p>
