UpdatePanel to prevent full Page Postback when using OnServer-Methods

Hi guys,

Is it somehow possible to use an UpdatePanel or else to prevent the full Page Postback when using OnServer-Methods?

When putting a Schedule Control inside an UpdatePanel within a standard fresh built ASP.NET Web Forms App with .NET 4.5 all other controls are not causing a full Page Postback inside an UpdatePanel with EnablePartialRendering enabled on the ScriptManager but the Schedule Control will do a Page Postback eg. for accessing the OnServerAppointmentCreated Method.

Thank you for contacting Syncfusion support. 
We have prepared the below sample using UpdatePanel to prevent the page reload on calling server methods. 
<asp:Content ID="BodyContent" ContentPlaceHolderID="MainContent" runat="server"> 
    <asp:UpdatePanel ID="UpdatePanel1" runat="server"> 
            <asp:AsyncPostBackTrigger ControlID="Schedule1" /> 
            <ej:Schedule ID="Schedule1" ClientIDMode="Static" Height="525px" Width="100%" CurrentDate="5/5/2014" runat="server" DataSourceID="SqlDataSource1" OnServerAppointmentClick="Schedule1_ServerAppointmentClick" > 
                <AppointmentSettings Id="Id" Subject="Subject" AllDay="AllDay" StartTime="StartTime" EndTime="EndTime" Recurrence="Recurrence" RecurrenceRule="RecurrenceRule" /> 
    <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:DefaultConnection %>" SelectCommand="SELECT * FROM [Appointment]"></asp:SqlDataSource>

Awesome. Works like a charm now!

Didn't had in mind that I was simply missing the AsyncPostBackTrigger.

Merry Xmas,
