        ConnectionString="<%$ ConnectionStrings:ConnectionString %>" 
        
        SelectCommand="SELECT classDetailsID,cd.classID,classType,startDate,endDate,batch,leftSlot FROM ClassDetail cd INNER JOIN Class c ON cd.classID=c.classID WHERE locationID=1 AND batch=2">
    </asp:SqlDataSource>
    
    <br/><br/><br/><br/><br/>
    <telerik:RadScheduler ID="RadScheduler1" runat="server"
            SelectedView="MonthView" DataEndField="endDate" DataKeyField="classDetailsID" 
        DataSourceID="SqlDataSourceSchedule" DataStartField="startDate" 
        DataSubjectField="classType" Height="" SelectedDate="2013-07-15" 
        EditFormDateFormat="d/M/yyyy" EditFormTimeFormat="h:mm tt" 
        EnableCustomAttributeEditing="True">
         <AdvancedForm Modal="True" EnableCustomAttributeEditing="True"></AdvancedForm>                
                 <AppointmentTemplate>
                    <div class="rsAptSubject">
                        <asp:Label ID="Label2" runat="server" Text="Label"></asp:Label>
                         <%# Eval("classType") %>
                    </div>
                  
               </AppointmentTemplate>

Hi Shi,

Please have a look at this code library project which deals with binding RadScheduler using an ASP SQL data source.

Thanks,
Shinu.
