I'm working through an exercise from your Ajax Courseware. When I place a RadCalendar inside an Ajax Panel, everything works fine. The Calendar updates as expected. When I go through the RadAjaxManager example, the calendar does not update when I click the next/prev ("<" ">") buttons, or the fast forward/back (">>" "<<") buttons.

I'm running VS2008, .Net 3.5SP1, Win 7 64 bit, RadControls Q3 2009 NET35

Some more info:

1) I get the same behavior if I run your sample without any changes ...\VS Projects\VS Projects\Ajax\CS\GettingStarted

2) If I disable Ajax in the AjaxManager smart tag, the calendar updates properly

3) If I click on the Month-Year heading of the calendar and select the new month/year that way, the calendar still does not update.

4) With Ajax enabled, the calendar is posting back to the server when I attempt to change the month with the < > buttons (breakpoint on Page_Load gets hit, Loading Panel on the label flashes very briefly).

Here's my markup and code-behind.

                    <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Default" %>

Hi Ken,

You can try the following modification to your manager declaration:

    
            <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"> 
        
                    <AjaxSettings> 
        
                        <telerik:AjaxSetting AjaxControlID="RadCalendar1"> 
        
                            <UpdatedControls> 
        
                                <telerik:AjaxUpdatedControl ControlID="Label1" /> 
        
                                <telerik:AjaxUpdatedControl ControlID="RadCalendar1" /> 
        
                            </UpdatedControls> 
        
                        </telerik:AjaxSetting> 
        
                    </AjaxSettings> 
        
            </telerik:RadAjaxManager>

I hope this helps
Johny
