Hi,

     Like Demo : https://dojo.telerik.com/ExuQuSoT

     Field title and description validation require is set true.

     I have a business need :

     When I choose Meeting Room 201 for Field RoomId, I hope that I can mask or turn off the validation and submit it normal.

     How to realize it?

     Thank you very much for your help. 

Hi,

      Method is https://docs.telerik.com/kendo-ui/knowledge-base/remote-validation?_ga=2.30044991.1233608935.1653012997-543877616.1650858150

      Demo is http://dojo.telerik.com/UgELisOy

      In above demo,  

      var remoteValidator = {
            valid: false,
            initiated: false,
            check: function(element, validator) {
            remoteValidator.initiated = true;
            //simulate Ajax
            setTimeout(function() {
                  //TODO: set to true if valid
                  remoteValidator.valid = true;

                  validator.validateInput(element);
                  remoteValidator.initiated = false;
            }, 1000);
          }
      };

      The form cannot be submitted normally.

       Thank you for your help!
