Date error

[Fillipe Barbosa]

Good Night,

I'm trying to show a DateTime field on grid, but when I refresh the grid, it's hide all DateTime fields or return Invalid Date.

See my code next:

<div id="divGrid" class="row">
    <div class="col-md-12">
 
        @Html.EJS().Grid("Index").DataSource((IEnumerable<object>)ViewBag.dataSource).Load("load").AllowResizing().AllowPaging().PageSettings(page => { page.PageSize(100); }).AllowSorting().AllowFiltering().FilterSettings(filter => { filter.Type(Syncfusion.EJ2.Grids.FilterType.Excel); }).AllowGrouping().Columns(col =>
   {
       col.Field("MensagemId").IsPrimaryKey(true).IsIdentity(true).Visible(false).Add();
       col.Field("type").HeaderText("Tipo").HeaderTextAlign(Syncfusion.EJ2.Grids.TextAlign.Center).TextAlign(Syncfusion.EJ2.Grids.TextAlign.Center).Width(30).Add();
       col.Field("ConteudoASCII").HeaderText("Mensagem").HeaderTextAlign(Syncfusion.EJ2.Grids.TextAlign.Center).TextAlign(Syncfusion.EJ2.Grids.TextAlign.Left).Add();
 
 
       col.Field("DataRegistro").HeaderText("Data Registro").HeaderTextAlign(Syncfusion.EJ2.Grids.TextAlign.Center).TextAlign(Syncfusion.EJ2.Grids.TextAlign.Center).Width(60).Add();
       col.Field("DataEnvio").HeaderText("Data Envio").HeaderTextAlign(Syncfusion.EJ2.Grids.TextAlign.Center).TextAlign(Syncfusion.EJ2.Grids.TextAlign.Center).Width(60).Add();
   }).SearchSettings(search => { search.Operator("contains").IgnoreCase(true).IgnoreAccent(true); }).Toolbar(new List<string>() { "Search" }).Locale("en-US").RecordDoubleClick("LoadRegistro").Render()
 
    </div>
</div>
 
 
 
@section Scripts {
 
 
    <script type="text/javascript" charset="UTF-8">
 
        //ej2.parse = false;

        function load(args) {
            this.columns[3].format = { type: 'date', format: 'dd/MM/yyyy HH:mm' };
            this.columns[4].format = { type: 'date', format: 'dd/MM/yyyy HH:mm' };
        }
 
        //REFRESH DEAFULT GRID
        function UpdateGrid() {
 
            var grid = document.getElementById("Index").ej2_instances[0]; // Grid instance
            var ajax = new ej.base.Ajax('/NotificacaoMensagem/DataSource', 'GET');
            ajax.send();
            ajax.onSuccess = function (data) {
                grid.dataSource = JSON.parse(data).result; LoadingOff();
                alert("1");
            };
        }

public partial class VNotificacao_GridMensagem
    {
        public int MensagemId { get; set; }
        public System.Guid MensagemUnique { get; set; }
        public string ConteudoASCII { get; set; }
        public string ConteudoBase64 { get; set; }
        public string fname { get; set; }
        public string caption { get; set; }
        public int type { get; set; }
        public System.DateTime DataRegistro { get; set; }
        public bool Pergunta { get; set; }
        public Nullable<System.DateTime> LimiteResposta { get; set; }
        public Nullable<System.DateTime> DataEnvio { get; set; }
        public Nullable<System.DateTime> DataExclusao { get; set; }
    }

public JsonResult DataSource()

               var Dados = cactusDBEntities.VNotificacao_GridMensagem.ToList();
 
               int count = Dados.Cast<VNotificacao_GridMensagem> ().Count();
 
               return Json(new { result = Dados, count = count }, JsonRequestBehavior.AllowGet);
 }

Hi Fillipe, 

Thanks for contacting Syncfusion support. 

We suggest you to parse the Grid data by using the “DataUtil.parse.parseJson” method to overcome the reported behavior. Please refer to the below code example for more information. 

[index.cshtml] 

@Html.EJS().Grid("Index").Load("load").Columns(col => 

{ 

    col.Field("OrderID").HeaderText("Order ID").IsPrimaryKey(true).Width("120").Add(); 

    col.Field("OrderDate").HeaderText("Data Registro").HeaderTextAlign(Syncfusion.EJ2.Grids.TextAlign.Center).TextAlign(Syncfusion.EJ2.Grids.TextAlign.Center).Width(60).Add(); 

}).AllowPaging().ActionFailure("fail").Render() 

 

 

<script> 

 

    function load(args) { 

 

        this.columns[1].format = { type: 'date', format: 'dd/MM/yyyy HH:mm' }; 

 

        var grid = document.getElementById("Index").ej2_instances[0]; // Grid instance 

 

        var result = JSON.parse(data).result; // data is a string contains result and count 

 

        grid.dataSource = ej.data.DataUtil.parse.parseJson(result); 

    }    

 </script> 

Please get back to us if you need any further assistance on this.
