Solution 1

Put this at the top of all controls, just after form tag starts:

XML

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

And also, put your CalendarExtender inside UpdatePanel.

About tag prefix: There is no issue in it. It's just an alias defined at the top of the page itself. Here:

XML

<%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="asp" %>

Whatever alias you define here, it works accordingly.

Yes. Read on how to use Update panel.

You need ContentTemplate in Update Panel and then put the extender in it.
Further, you missed closing tags of update panel.
