Required vs Optional Resources

[Brian Mains]

Hello,

With resources, is it possible to have some of the resources required and some optional?  What I mean is can the Scheduler do the validation, like it does for the subject message?

Thanks.

Hi Brian,

You can do simple validation using the AppointmentInsert/AppointmentUpdate events. Cancelling them will abort the operation and return the user to the form:

protected void RadScheduler1_AppointmentInsert(object sender, SchedulerCancelEventArgs e)
{
    if (e.Appointment.Resources.GetResourceByType("Calendar") == null)
    {
        e.Cancel = true;
    }
}

You can use ScriptManager.RegisterStartupScript to show the user a message about what went wrong. More elegant validation can be done using the advanced template.

I hope this helps.
