Scheduler Height Error on binding data

[Suderson]

Hi,

We are binding few appointments to the scheduler. By default, it will be in month view. But when we click Day View or Week View, an error is been thrown from Javascript and still the scheduler appears in Month View.

The error is as follows:

Error: Sys.WebForms.PageRequestManagerServerErrorException: Height must be non negative.
Parameter name: value

Any hint on solving this issue is appreciated.

Hello Suderson,

Can you please check if you set the GroupBy property?

A code snippet of your implementation would be helpful in providing us with clues.

Hi.

Wee are making Datakey field of the scheduler to a composite key. This data key will have description with start time and end time. So, in what way group by is useful here??

Here is the design code:

<telerik:RadScheduler ID="radSchedular" ReadOnly="true" runat="server" SelectedView="MonthView"
                            Width="100%" Height="100%" OverflowBehavior="Expand" DataKeyField="allDetails"
                            DataSubjectField="Description" DataStartField="CustDate" DataEndField="DateCompleted"
                            TimeZoneOffset="03:00:00" FirstDayOfWeek="Monday" ShowFullTime="True" LastDayOfWeek="Sunday"
                            WorkDayEndTime="23:00:00" WorkDayStartTime="00:00:00" Skin="Web20" OnAppointmentCreated="radSchedular_AppointmentCreated"
                            OnDataBound="radSchedular_DataBound" OnClientTimeSlotContextMenu="CancelInserting"
                            AllowDelete="False" AllowEdit="False" AllowInsert="False">
                            <TimelineView UserSelectable="false" />
                        </telerik:RadScheduler>

This is the code which will populate the scheduler

private void BindScheduler()
    {
        XmlDataProviderForSchedular objclass = new XmlDataProviderForSchedular();
        radSchedular.DataSource = objclass.GetAllAppointments();
        radSchedular.DataBind();

    }

Hi Suderson,

The GroupBy property can be used if you have defined resources. If that's not the case, please open a support ticket and send us a simple working demo of the problem.

All the best, Peter

Apart from this, we have a problem in the Next and previous month navigation. When we click any of the button, it is going to the top of the page and coming down to the control. My client hates this behaviour. We already have the control inside the update panel. Still we have the issue. But this behaviours is not occuring when we click the calendar in the scheduler and move to the oither months.

We are surprised with the kind of behaviour it has in the next and previous month navigation. We tried removing the update panel and using the telerik ajax settings, still fails. Can anyone help me. IS this the problem with the control. The code is already in the site. Please see above

Please help us.

Hello Suderson,

Can you send us a live url of the issue or open a support ticket and attach a simple demo which we can test?
Note that we cannot replicate such a problem with the online demos.

Kind regards,

The following is the code for the control and populating it.

<telerik:RadScheduler ID="radSchedular" ReadOnly="true" runat="server" SelectedView="MonthView"
Width="100%" Height="100%" OverflowBehavior="Expand" DataKeyField="allDetails"
DataSubjectField="Description" DataStartField="CustDate" DataEndField="DateCompleted"
TimeZoneOffset="03:00:00" FirstDayOfWeek="Monday" ShowFullTime="True" LastDayOfWeek="Sunday"
WorkDayEndTime="23:00:00" WorkDayStartTime="00:00:00" Skin="Web20" OnAppointmentCreated="radSchedular_AppointmentCreated"
OnDataBound="radSchedular_DataBound" OnClientTimeSlotContextMenu="CancelInserting"
AllowDelete="False" AllowEdit="False" AllowInsert="False">
<TimelineView UserSelectable="false" />
</telerik:RadScheduler>

This is the code which will populate the scheduler

private void BindScheduler()
{
XmlDataProviderForSchedular objclass = new XmlDataProviderForSchedular();
radSchedular.DataSource = objclass.GetAllAppointments();
radSchedular.DataBind();

}

Hi Suderson,

I suspect the problem could be with your custom provider and the way you initialize it. Here is a help topic for reference - http://www.telerik.com/help/aspnet-ajax/scheduler-using-data-provider.html

You can set the provider from code-behind too. For example -

protected override void OnInit(EventArgs e)
 {
     base.OnInit(e);
     RadScheduler1.Provider = new XmlSchedulerProvider(Server.MapPath("~/App_Data/Appointments.xml"), true);
 }

Attached are too samples for your perusal.

Hi,

We tried the things you mentioned and also gon through the samples that you have given, unfortunately we weren't able to solve it. Still both the problem persists

Hi Suderson,

Without a sample project, I cannot be sure what could be causing the issue.

I see this error too some of the time.  We have three sites, call them A, B and C and we're displaying rooms from those sites as resources on the scheduler.  Site A has 7 rooms, Site B has 193 rooms and Site C has 295 rooms.  Switching between month and timeline view works fine when viewing Site A, but I get the above errors (and some others like them) when trying to switch to month view on Site B or Site C.

Clearly there's some boundary between 7 and 193 where there's too many resources for the scheduler to display in month view because it causes an overflow somewhere in a height calculation.  I've not worked out whereabouts that boundary is yet.

Even when I restrict to as few as ten resources I can still trigger the error.  It seems that the number of appointments is also a factor.

Hello,

I have tested the RadScheduler defined as in the Jyoti's post, but I was unable the replicate the described troubled behavior. In order to identify the cause of this issue we will need a sample project/page on which it is replicated so we will be able to troubleshoot the problems locally.

Thank you!

I have created a support ticket.
