Delete event not called.

[hardik]

Hi telerik,

I create one test application using scheudlerView.

I found one bug into it. When I click on the delete icon of appointment at that time AppointmentDeleting or AppointmentDeleted event not called. This is happen only when I cancel the  event

private void XamlRadScheduleView_ShowDialog(object sender, ShowDialogEventArgs e)
    {
      // This will cancel default ScheduleView dialogs.
      e.Cancel = true;
    }

Is that any bug or I need to add some logic.?

Thanks
Hardik

Hi hardik,

This is expected behavior, because when the user tries to delete an appointment, a confirmation dialog is shown first and after the deletion is confirmed, the events are fired. So when you cancel ShowDialog event, you prevent this dialog from displaying. In order to workaround this, you can set DefaultDialogResult property of the ShowDialogEventArgs to true like this:
 

private void XamlRadScheduleView_ShowDialog(object sender, ShowDialogEventArgs e)
{
    e.DefaultDialogResult = true;
    e.Cancel = true;
}

All the best,

Hi yana,

As per your suggestion I do the code but now I am facing another problem with it.

After

private void XamlRadScheduler_ShowDialog(object sender, ShowDialogEventArgs e)
    {
      e.DefaultDialogResult = true;
      e.Cancel = true;
    }

this coding

deleting is called but appointment is deleted  temporarily(not shown) from there even though I select cancel from my own popup.After refreshing the schedulerView again that appointment is shown there.

Same problem I am facing with creating also when I double click in calendar then I cancel default popup by e.cancel = true. And from my popup I cancel the appointment creation than also one appointment is shown there. And after refreshing it will not whon there.

Same thing happen in test application also. I just done above coding and when I double click in scheudlerView then appointment is created. see the Image.

Thanks
Hardik

Hi hardik,

The recommended approach to display custom appointment dialog is to change the EditAppointmentDialogStyle property of the ScheduleView control as described in this blog post.
You can use DeleteAppointmentConfirmDialogStyle property to customize the delete confirmation dialog.
Canceling ShowDialog event and displaying custom popups may have unpredictable results.

Please try the approach and let us know how it goes.

thanks for reply.

I have solve the issue. e.cancel = true in XamlRadScheduleView_AppointmentEditing event and

 private void XamlRadScheduleView_ShowDialog(object sender, ShowDialogEventArgs e)
    {
      // This will cancel default ScheduleView dialogs.
      e.DefaultDialogResult = true;
      e.Cancel = true;
    }

now its working.,

Thanks

By the way: Is it possible to get to know which dialog is going to be shown inside the ShowDialogEvent?

Hello Marcus,

You should check the DialogViewModel property of the ShowDialogEventArgs to find the dialog that will be shown. More information about ShowDialog event can be found here and here.
