Appointment Datasource / asynchronous loading

[Rudolf]

Dear Telerik Team,

i have a little quest.

I Have a RadScheduleView Control, with an AppointmentDatasource, which get's the Appointments from
a Webservice.

My Problem is, that the Appointments will be loaded by to Webservice calls

Step 1. FreeBusyAppointments
Step 2. ExchangeAppointment Details

Step 1 work very well and very fast, but Step 2. needs a lot of time, because the Backendservers are very slow while fetching the data.

So my solutions ist, that i turn on a busy indicator, loading Step 1 from the Webservice, put the Appointments into the RadschedulerView,
then turn off the busy inidcator and start a backgroundworker which loads the ExchangeAppointment details. When Step 2 is finished
the Appointments will be added to the Rad Scheduleview.

This should give users the possibility to see and user the radscheduleview before all appointment details are loaded.

That's the plan.

The Problem is, that after i turn of the busy indicator and starting the backgroundworker,
i see the freebusy appointments in the radscheduleview, but the busy indicator is also stil shown,
but it hangs up (including the InternetExplorer) until all Appointments from step 2 are loaded and filled into the radscheduleview.

I can easily reproduce this with filling some static Appointments in the RadScheduleview while blocking the Backgroundworker process with a 

System.Threading.Thread.Sleep(xxxx);

Is there any Solution about such a scenario - because the Step 2. can take up to 30 seconds, and the control is unusable during this period

thanks for your help

kind regards
Rudi

Hi Rudi,

I tried to reproduce the problem, but to no avail. You can find the attached sample project. At start up, some basic appointments are loaded (in 5 secs delay) and after that on completed event in the background worker new 2 appointments are added to the ScheduleView control. Please, take a look and let me know if I miss something. 

I am glad to assist you further.

Regards,
George
