Does anyone has idea on this ??


My coding is as below :

<telerik:RadScheduler ID="RadScheduler1" runat="server" GroupBy="LineNum"
        DataKeyField="ID" DataSubjectField="Desc"
                DataStartField="StartDate" DataEndField="EndDate"
                DataRecurrenceField="ID" SelectedDate="2010-04-22"
                DataRecurrenceParentKeyField="ID" RowHeaderWidth="52px"

Hi Johnson,

It seems like you haven't defined the LineNum resource type. Please, refer to this help topic for information on how to define resources:

http://www.telerik.com/help/aspnet-ajax/schedule_designcustomresourcesandattributes.html

Look at this example as well:

http://demos.telerik.com/aspnet-ajax/scheduler/examples/resources/defaultcs.aspx

I hope this helps.

Kind regards,

Hi, thanks for your kind reply.

I have ammend it as below. Now it is able to do grouping but after grouping all the data lost.
I think that i am quite close to the point already, just 1 step away.

My code behind is as below:

<ajax:RadScheduler runat="server" ID="RadScheduler1" DayEndTime="19:00:00" TimeZoneOffset="03:00:00"
              DataKeyField="ID" DataSubjectField="Desc"
                DataStartField="StartDate" DataEndField="EndDate" SelectedView="TimelineView"
                 OverflowBehavior="Expand" ShowViewTabs="False"
                >
                <AdvancedForm Modal="True" />

         <TimeSlotContextMenuSettings EnableDefault="True" />
         <AppointmentContextMenuSettings EnableDefault="True" />
       <ResourceTypes>

       </ResourceTypes>
            </ajax:RadScheduler>

My coding is as below:

Can you please advice me which part i miss out ??

hi, i have get it solved  by doing this  cResourceType.KeyField = "LineNum"
