            {
                #region Bulk FloodData Upload process
                try
                {
                    using (var context = new CATConnection_DevEntities())
                    {
                        using (var conn = db.Database.Connection)
                        {
                            conn.Open();
                            var FloodDT = Global.ConvertToDataTable(ListFloodView.FloodViewModels.ToList());
                            var command = conn.CreateCommand();
                            command.CommandText = "[dbo].[InsertFloodFile]";
                            command.CommandType = CommandType.StoredProcedure;
                            command.CommandTimeout = 300;
                            var parameterLogedInID = new SqlParameter("@LogedInID", LogedInID);
                           
                            using (var reader = command.ExecuteReader())
                            {
                            }
                        }
                    }
                    return this.ResponseMessage(Request.CreateResponse(HttpStatusCode.OK, new
                    {
                        Status = Global.Status.OK.ToString(),
                        Message = Global.StatusMessage.Created.ToString()
                    }));
                }
                catch (Exception ex)
                {
                    Global.InsertException(ex);
                    return this.ResponseMessage(Request.CreateResponse(HttpStatusCode.BadRequest, new { Status = Global.Status.NotFound.ToString(), Message = Global.StatusMessage.NotFound }));
                }
                #endregion              
            }

i basically want to set an error message for lossDate and CompletedDate property if user sets  string value in this datetime field

Hi @Basit Nisar,

You can use model validation to specify a custom display format for field values through the DisplayFormat property.

 [DisplayFormat(DataFormatString = "{0:MM/dd/yyyy}", ApplyFormatInEditMode = true)]
 public DateTime? LossDate { get; set; }

Best regards,

Lan Huang
