ValidationMessageFor won't display in Template Pop-up Window

[Alex]

I can tell it's returning the right message, but it never displays the message.  What am I missing?

DateValidator:

using System;

using System.ComponentModel.DataAnnotations;

 

namespace PosPayAndBankRec.Models.Validators

{

    public class Date

    {

        public enum ValidationType

        {

            RangeValidation,

            Compare

        }

  

        public class DateValidationAttribute : ValidationAttribute

        {

            private ValidationType _validationType;

            private DateTime? _fromDate;

            private DateTime _toDate;

            private string _defaultErrorMessage;

            private string _propertyNameToCompare;

 

            public DateValidationAttribute(string message, string compareWith = "")

            {

                _propertyNameToCompare = compareWith;

                _defaultErrorMessage = message;

            }

            protected override ValidationResult IsValid(object value, ValidationContext validationContext)

            {

                var baseProperyInfo = validationContext.ObjectType.GetProperty(_propertyNameToCompare);

                DateTime startDate;

                bool NotValid = false;

 

                if (baseProperyInfo.GetValue(validationContext.ObjectInstance, null) is DateTime)

                {

                    startDate = (DateTime)baseProperyInfo.GetValue(validationContext.ObjectInstance, null);

 

                    if (value != null)

                    {

                        DateTime thisDate = (DateTime)value;

 

                        if (thisDate <= startDate)

                        {

                            NotValid = true;

                        }

                    }

                    else if (value == null)

                    {

                        //From date as a value but not the to date

                        NotValid = false;

                    }

                }

                else

                {

                    //To  date not a date and we have a from date

                    if (value != null)

                    {

                        NotValid = true;

                    }

                }

 

                //return validation result

                if (NotValid == false)

                {

                    return null;

                }

                else if (NotValid == true)

                {

                    string message = string.Format(_defaultErrorMessage, validationContext.DisplayName);//, displayAttr.Name);

                    return new ValidationResult(message);

                }

                return null;

            }

        }

    }

}

TreasuryModel:

[Date.DateValidation("Deactivation Date should be greater than the Activation Date.", compareWith: "brActivationDate")]

public Nullable<System.DateTime> brDeactivationDate { get; set; }

TreasuryPopupTemplate:

                <td>

                    @Html.EditorFor(model => model.brActivationDate)

                    @Html.ValidationMessageFor(model => model.brActivationDate)

            </td>

            <td>

                    @Html.EditorFor(model => model.brDeactivationDate)

                    @Html.ValidationMessageFor(model => model.brDeactivationDate)

            </td>

Hello Alex,

The information you provided is not enough to tell you what exactly is going wrong.
I would like to ask you few questions.

 What is your exact setup - do you set this fragment you shared as content of the Window - if so, how is it with Ajax?
Does the validation work when you are not using Kendo.Window? Does your validation support client side validation?
Could you send us a runnable project?

Kind Regards,
