Validation for AdvancedEditTemplate

[Kati]

I am using an AdvancedEditTemplate. When the user clicks on the 'Update' button, RadScheduler1_AppointmentCommand gets called. Here I am validating the fields. The screen will go back to the origianl calendar grid view, no matter what. I really need to keep the user on the edit for view, if the validation fails and show them a message. This way the appointment doe not get save, but the user doesn't know what's happening. Any way of doing this?

Thanks a lot

The Scheduler control doesn't have the KeepInEditMode property like the Grid control does so it's not a built-in feature.

A good work-around should be something like this:

-- perform validation

// check if validation failed

if (!valid)

{

// cancel the event

e.Cancel = true;

// show the edit form again for the appointment

scheduler.ShowAdvancedEditForm(e.Appointment)

-- show message

}

The code above is assuming you're using the AppointmentInsert/AppointmentUpdate events, since they can be canceled.

I hope that helps.

If you're using the edit mode you can replace e.Appointment with e.ModifiedAppointment, so that it retains any of the changes they might have made. I haven't tried it out, but I'm assuming it will work.

Sorry, ignore my previous post.
How do I get back a custom attribute value in  RadScheduler1_AppointmentUpdate please?

Hi Kati,

Have you tried e.Appointment.Attributes["MyCustomAttribute"]?

Kind regards,

Yes
I'm getting this error

  e.ModifiedAppointment.Attributes["txtNotes"] is null

It's returning null because I don't think the ModifiedAppointment object retains the attributes set in the Appointment object. You would need to get the attribute from the Appointment object.
