get Appointment by id

[piotre6]

Is it possible to get appointment (needed for editAppointment function) by id on client side?
I have tried to use  scheduler.get_appointments(), unfortunately it only shows appointments oc current view.

Hi Piotre6,

Indeed, you can only access appointments that are rendered (fall in the visible range). Then you could use-

scheduler.get_appointments().findByID(56).get_subject()

I have followed the instruction to create dbschedulerprovider and webservice. I 'm trying to consume webservice with following code:

$.ajax({
    type: "POST",
    url: "GuaranteeModule/GuaranteeSchedulerWebService.asmx/GetAppointments",
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    data: "{'schedulerInfo':{}}",
    success: function(msg) {
        AjaxSucceeded(msg);
    },
    error: AjaxFailed
});

While debugging on server side everything seems to be fine, unfortunately on client side I receive following error:

Hello Piotre6,

I haven't tested this way of binding RadScheduler to a web service to be honest. I wonder if there is a reason why you cannot use the approach from the online demo and set:

    <WebServiceSettings Path="SchedulerWebService.asmx" ResourcePopulationMode="ServerSide" />

Attached is also a working demo for reference.

You are welcome to open a support ticket and send us a sample of your implementation so we can test it locally.


Kind regards, Peter

On my page I have radgrid that displays all appointments and radscheduler with defaultview=timeline to present current week appointments and deal with reminders. I use radscheduler's advanced template to edit appointments.
I want be able to edit appointment when double clicked on grids row:

function onGridRowDblClick(sender, eventArgs)
{
    var scheduler = $find('<%= RadScheduler.ClientID %>');
    var warrantyId = eventArgs.getDataKeyValue("WarrantyId");
    var appointments = scheduler.get_appointments();
    var appointment = appointments.findByID(warrantyId);
    if(appointment != undefined)
    {
        scheduler.editAppointment(appointment, true);
    }
    else
    {
        createNewAppointment();
    }
}

My problem is that get_appointments() returns only appointments that are in current scheduler view. When I double click on appointment that is not shown on in scheduler appointments.findByID(warrantyId) returns null.

Hello Piotre6,

Yes, this is indeed how th findById method works. As a workaround, I suggest you navigate to the date of the appointment with scheduler.set_selectedDate and handle RadScheduler's OnClientDataBound to find the appointment by id. Here is a sample code:

function onGridRowDblClick() {

           var scheduler = $find('<%= RadScheduler1.ClientID %>');

           //Here you should be able to pull the values of
           //the Start time and ID of the appointment from the grid event
           appId = "9";
           scheduler.set_selectedDate(new Date());


       }
       function OnClientDataBound(sender, args) {
           if (appId != null) {
               var scheduler = sender;
               var appointments = scheduler.get_appointments();
               var appointment = appointments.findByID(appId);

               if (appointment != null) {
                   scheduler.editAppointment(appointment, true);
               }
               appId = null;
           }
       }
       * * *


 <telerik:RadScheduler ID="RadScheduler1" runat="server" OnClientDataBound="OnClientDataBound" .../>

I have replaced new Date() with new Date(stringStartDateFromGrid). Date seems to be ok.
After scheduler.set_selectedDate(new Date(stringStartDateFromGrid)) nothing happens.

No matter if I put new Date() or new Date(stringStartDateFromGrid) OnClientDataBound never occurs

Hello Piotre6,

I wasn't able to replicate the problem with the file you sent. We can probably be able to pinpoint the issue if you send us a working sample which we can run without modifications.


All the best, Peter
