Created Unassigned: CalendarExtender doesn't work anymore [27478]

Hi, I just update the project to the last version of the toolkit and the CalendarExtender doesn't work anymore.

No error is reported, but when I click on the textbox the calendar is not showing.



```
<%@ Register TagPrefix="asp" Namespace="AjaxControlToolkit" Assembly="AjaxControlToolkit"%>
-----------
<asp:TextBox ID="txtSelectedDay" runat="server" Height="24px"></asp:TextBox>

<ajaxToolkit:CalendarExtender runat="server" ID="calendarExtender"
TargetControlID="txtSelectedDay"
CssClass=""
Format="MMMM d, yyyy" />

<asp:ScriptManager ID="ScriptManager1" runat="server">
```


it worked perfectly in the previous version.


Just one note: I see from http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/Calendar/Calendar.aspx that the CalendarExtender is not present anymore :|

But I can't find this "Calendar" control in the assembly
