Implementing Multiuser Scheduler?

[Tree]

I'm looking for advice on the best way to implement a scheduler in a web app that will have multiple users creating/editing appointments.  I need to make sure that every user's schedule is updated periodically.

Performance is always an issue so I'd like to try the new web service feature of RadScheduler.  If I do, I don't know how to initiate a refresh from the client (If I were using normal postbacks I'd just do a RadAjaxTimer).  Any advice?

As for collisions (two users editing the same appointment) I think I can just deal with that in my Scheduler's data provider.

Hello,

Thank you for this question.

We plan to implement auto-refresh (with polling) and expose a public Refresh method in the client API of RadScheduler.

Meanwhile, there is a workaround that you can use. Referring to the Ajaxify Timer demo, try the following

 <script type="text/javascript">
           function OnRequestStart(sender, eventArgs)
           {
            refreshSchedulerClientSide();
           }
           function refreshSchedulerClientSide()
           {
            var scheduler = $find('<%= RadScheduler1.ClientID %>');
            scheduler.set_selectedDate(scheduler.get_selectedDate());
           }
           </script>
            <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"
            ClientEvents-OnRequestStart="OnRequestStart"
            UpdatePanelsRenderMode="Inline">

Peter,

Thanks for the workaround.  I assume this will ONLY work when the scheduler is in the regular postback mode (rather than the web service mode). Correct?

Is there any way I can do periodic polling to refresh the scheduler while it is in the web service mode?

[Peter]

Actually, just the opposite - the workaround is intended to be used when RadScheduler is in web service mode. I believe this is what you asked for. In the Ajaxify Timer demo, you will notice that RadGrid is refreshed from code behind with this code:

 public void Timer1_Tick(object sender, EventArgs e)
        {
            RadGrid1.Rebind();
        }

With the workaround I suggested you will not have to call RadScheduler1.Rebind() in the Tick event.


Kind regards,

Thanks!  I'll give it a try.
