Prev/Next Month not working

[Suzanne]

The Previous < and Next > month buttons do not update the calendar when they are clicked using the following .aspx code with Telerik.Web.UI version 2010.1.415.35.

<telerik:RadSplitter runat="server" ID="RadSplitter1" PanesBorderSize="0" Width="734px"

Hi Suzanne,

Can you confirm that the provided markup is sufficient to reproduce the problem? My local tests with it does not seem to exhibit any unexpected behavior. Is there something else needed to replicate the issue?

Sincerely yours,

Sorry - I have a second splitter and a right pane after the markup sample given.  I found If I remove the right pane, the prev/next month functionality works.  Here is the additional markup.

<telerik:RadSplitBar runat="server" ID="RadSplitBar2" CollapseMode="Forward" />
       <telerik:RadPane runat="Server" ID="rightPane" Scrolling="None">
           <asp:UpdatePanel UpdateMode="Conditional" ID="upnlSchedule" runat="server">
               <ContentTemplate>

                   <h2 class="hl2">
                   <asp:Label ID="lblSelection" runat="server" Text="loaded..." Visible="false"></asp:Label>
                   </h2>
                   <telerik:RadScheduler runat="server" ID="RadScheduler1" Skin="Office2007"
                       SelectedDate="2010-03-30"
                       DataKeyField="ID" ShowAllDayRow="false" WeekView-ColumnHeaderDateFormat="ddd, d"
                       DataSubjectField="Subject" DataStartField="StartTime" DataEndField="EndTime"
                       OverflowBehavior="Expand" SelectedView="WeekView" FirstDayOfWeek="Monday" LastDayOfWeek="Friday"
                       EnableCustomAttributeEditing="True"

                       onformcreated="RadScheduler1_FormCreated"  DayEndTime="17:00:00"

                       MinutesPerRow="15" TimeLabelRowSpan="4"
                       CustomAttributeNames="LastName,FirstName,Phone,AppointmentId"  >
                       <WeekView WorkDayEndTime="17:00:00" WorkDayStartTime="09:00:00" />

Hello Suzanne,

The problem is that you are not ajaxifying the control correctly. You can observe the same behavior if you use the regular asp Calendar. One option to make it work is to put the update panel around all of the controls:

<asp:UpdatePanel UpdateMode="Conditional" ID="upnlSchedule" runat="server">
            <ContentTemplate>
                <telerik:RadSplitter runat="server" ID="RadSplitter1" PanesBorderSize="0" Width="734px"
                    Height="782px" Skin="Office2007">
                    <telerik:RadPane runat="server" ID="leftPane" Width="260px" MinWidth="260" MaxWidth="300"
                        Scrolling="None">
                         <telerik:RadCalendar runat="server" ID="RadCalendar1" Skin="Office2007" AutoPostBack="True"
                            EnableMultiSelect="False" DayNameFormat="Shortest"
                            CellAlign="Center"
                            CellVAlign="Middle" FirstDayOfWeek="Default"
                            MonthLayout="Layout_7columns_x_6rows" Orientation="RenderInRows"
