Asked On January 13, 2019 02:04 PM UTC

Hi,
I'm sorry that I have to bother you with this, I couldn't find an example in the documentation although I am sure it does exist.
In https://ej2.syncfusion.com/aspnetcore/Schedule/EditorValidation#/material is a description of how to attach validation rules to members of 
<e-eventsettings-fields>, e.g. <e-field-subject name="Subject" validation="ValidationRules"></e-field-subject>

I have added additional fields to the Editor window using the popupOpen Event; one of those is e.g. an Option to select if the appointment is open, closed or to be approved by the Owner for other people.
So now I have an e-field named ListOption, which is a DropDown of [{"Id":0,"Name":"Unknown"},{"Id":1,"Name":"Open"},{"Id":2,"Name":"Closed"},{"Id":3,"Name":"Approve"}];

On saving the Appointment, I would like to make sure that ListOption is not empty, and that the value is between 1 and 3 (ie not "None").

How can I attach that validation?
Thank you very much for your assistance. Please let me know should you require a full example and I shall provide one on stackblitz.
