2 issues found with RadScheduler and need some hints

[Seree]

Hi,

First of all, I want to thank you for producing such a great product like RadScheduler.

Anyway, after I have purchased and try a bit more with it in my current project, I got 2 issues which need your kindly helps/hints to sort it out.

The 1st one is that I got a script error message everytime my mouse cursor hover over any appointment which you can see in the first attachment. (I have implemented a custom provider and post the code below)

The 2nd one is that the resource header row is not well aligned correctly with the appointment area which you can see in the second attachment.

Please suggest.

Here is my custom provider code.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using AIAPS.DomainModel.Entities;
using AIAPS.DomainModel.Repositories;
using Telerik.Web.UI;

namespace AIAPS.DomainModel.Utilities
{
    public class ApsSchedulerProvider : SchedulerProviderBase
    {
        private List<Resource> _resources;

        private void LoadResources()
        {
            _resources = new List<Resource>();

            Resource res = new Resource("Machine", "M-001", "M-001");
            _resources.Add(res);
            res = new Resource("Machine", "M-002", "M-002");
            _resources.Add(res);
            res = new Resource("Machine", "M-003", "M-003");
            _resources.Add(res);
            res = new Resource("Machine", "M-004", "M-004");
            _resources.Add(res);
            res = new Resource("Machine", "P-001", "P-001");
            _resources.Add(res);
            res = new Resource("Machine", "P-002", "P-002");
            _resources.Add(res);
        }

        public ApsSchedulerProvider()
        {
            LoadResources();
        }

        public override void Delete(RadScheduler owner, Appointment appointmentToDelete)
        {
            throw new NotImplementedException();
        }

        public override IEnumerable<Appointment> GetAppointments(RadScheduler owner)
        {
            //throw new NotImplementedException();
            List<Appointment> appointments = new List<Appointment>();
            foreach (ApsProcessTimeline timeline in ApsProcessTimelinesRepository.List.OrderBy(t => t.BeginTime))
            {
                Appointment app = new Appointment();
                app.ID = timeline.ApsProcessTimelineId;
                app.Start = timeline.BeginTime.Value;
                app.End = timeline.FinishTime.Value;
                app.Description = timeline.MachineID;
                app.Subject = timeline.MachineID;
                app.Resources.Add(new Resource("Machine", timeline.MachineID, timeline.MachineID));
                appointments.Add(app);
            }

            owner.TimelineView.ShowResourceHeaders = true;
            owner.TimelineView.GroupBy = "Machine";
            owner.TimelineView.GroupingDirection = GroupingDirection.Vertical;
            //owner.TimelineView.NumberOfSlots = appointments.Count;
            owner.TimelineView.HeaderDateFormat = "dd/MM/yy";

            owner.SelectedDate = appointments[0].Start;

            return appointments;
        }

        public override IEnumerable<ResourceType> GetResourceTypes(RadScheduler owner)
        {
            //throw new NotImplementedException();
            List<ResourceType> resourceTypes = new List<ResourceType>();
            resourceTypes.Add(new ResourceType("Machine"));
            return resourceTypes;
        }

        public override IEnumerable<Resource> GetResourcesByType(RadScheduler owner, string resourceType)
        {
            //throw new NotImplementedException();
            return _resources.FindAll(delegate(Resource res) { return res.Type == resourceType; });
        }

        public override void Insert(RadScheduler owner, Appointment appointmentToInsert)
        {
            throw new NotImplementedException();
        }

        public override void Update(RadScheduler owner, Appointment appointmentToUpdate)
        {
            throw new NotImplementedException();
        }
    }
}

*Note that currently I have only one type of resource which is "Machine" and it is being stored on "MachineID" field.

I am looking forward for your suggestion.

Thank you and best regards,
Seree W.

Hello Seree,

Can you isolate the issues in a simple working demo and send it to us via a support ticket?

I've encountered this error as well.  I recently upgraded from a very old version (A 2007 version, forget which one) to the latest release.  I've had to do some minor changes but I receive the same error the previous poster gets whenever I try to hover over an existing appointment.  This is the line that throws the error in the Telerik javascript:

var l=(j.get_allowDelete()!=null)?j.get_allowDelete():this.get_allowDelete();

Hi Chris,

Thanks for participating in the thread.

After I have submitted my issue through support ticketing system, I got replied from Telerik that this is somewhat a weird behavior occur on the webforms within MVC 2 web application project and Telerik need sometime to sort it out.

So, the alternative suggestion is to build an external application as a generic ASP.NET web application and put the RadScheduler there.

If I found another solution, I will share here.

Hope this help,
Seree W.

Hi,
I was experiencing the same error in my web application. The error was occuring in the Month & Week view in the case when after the initial scheduler bind (for a given date range), i selected  another date within the same date range for which the scheduler was showing data.

In my case i had created a custom calendar provider ( fetching data from 2 different systems: database and webform) and in order to improve performance i was storing the appointment collection of the last date range when the Getappointment method was called. Now if the next call to the Getappointment was for the same  range i used return the stored appointment collection object instead of polling and creating the appointments again.

After debugging for a while it randomly struck me to comment the caching/storing part. Once i removed the storing part and returned colection afresh the error was resolved.

Although not much of an explnation to the cause, but hopefully the teleik team might make out something from this. 

regards,

Rajesh

Hi,
 
Just adding to the my previous post.

Now instead of storing the Rad Appointment List, i now store the datables returned from the source and create a new appointment list from these stored datatables and return it. This works fine and i am not getting the javascript error with this approach.

Thanks
Rajesh

Hi

I seem to be also getting a script error. When I click dismiss in the reminder popup the script error appears. While im running this on localhost the error was indicated on the line;

var t=g.raiseCancellableControlEvent(this,"reminderDismissing",{appointment:v.get_owner(),reminder:v});

Error shown in attachment.

Either clicking yes or no on the error box does nothing. It just reappears when you try to do anything else.

Any help appreciated
Thanks
Phil

Hi

I have further looked into the error and found what seems to make the error occur.

This error seems to be if the scheduler has more than one appointment on one reminder.
When the reminder popup appears the first appointment is selected. If a user clicks the dismiss button at this point, it will dismiss the appointment selected. After the selected appointment has been dismissed (if you have more than one appointment on the same reminder), the scheduler will not select the second appointment and then when the users trys to click dismiss again the error appears.

Is there a way to select the second appointment after you dismiss the first appointment?

Thanks
Phil

Hello Phillip,

Thanks for reporting this.

It is a bug in the RadScheduler. It will be fixed soon and here you can find the PITS Issue: Public URL

P.S: I've increased your points for reporting the bug.

I am struggling with the 2nd issue that Seree pointed out and after combing through these forums I am not seeing an answer. When I have multiple appointments in the same slot, the slot grows, but the corresponding resource cell does not.  And then the appointments become completely misaligned with their resources.

Any ideas?
Thanks
Seth

Hello Seree,

Could you please send us a sample project that reproduces the issue or could you please check whether this occures in our demos? We'll appreciate if you can guide us to the steps for reproducing this.

All the best,

Hi Seth,

Did you find a resolution for this? We seem to be running into the same issue.

Thanks,
Carl

Hi,

 
Would you please share if the issue is still reproduced in some of our on-line demos. You can also refer to this documentation article where in the last section is showing one way to workaround this misalignment.

Regards,

This happens for me in the TimelineView when grouping by Resource and an appointment has more than one resource. I don't see that any of the online demos have this same scenario. I will try the workaround that you mention.

[Carl]

The workaround in the article seems to have worked for me. Thanks.
