为什么从浏览器URL重新加载Kendo UI GRID页面时，所有数据均不显示，而仅显示不包含数据的网格？

Question

当我重新加载kendo网格页面时，信息丢失，您必须停止该程序并重新启动它！我的问题在哪里以及如何解决？

这是我在ASP.NET MVC 5中对kendo ui网格的看法：

@using Microsoft.AspNet.Identity.EntityFramework;
@using UserManagerSample.ViewModels;
@using Kendo.Mvc.UI


<script 
src="http://cdn.kendostatic.com/2013.3.1119/js/kendo.aspnetmvc.min.js"> 

     @(Html.Kendo(). Grid<UserViewModel>() .Name("grid")
     .Columns(columns =>
      {
      columns.Bound(p =>
      p.UserName);

    columns.Bound(p => p.password);
    columns.Bound(p => p.ConfirmPassword);
    columns.Bound(p => 
     p.Fakerole).ClientTemplate("#=Fakerole.FakeRoleName#")
  .Title("Role").EditorTemp 
  lateName("FakeRoleDropDownList").Width(180);

     columns.Command(command => command.Destroy()).Width(150);
   })
   .ToolBar(toolBar =>
    {
    toolBar.Create();
    toolBar.Save();
})
 .Editable(editable => editable.Mode(GridEditMode.InCell))
.ClientDetailTemplateId("Test")
.Pageable()
.Sortable()
.Scrollable()
.HtmlAttributes(new { style = "height:550px;" })
.DataSource(dataSource => dataSource
    .Ajax()
    .Batch(true)
    .ServerOperation(false)
    .Events(events => events.Error("error_handler"))
    .Model(model =>
    {
        model.Id(p => p.UserId);

        model.Field(p => p.UserId).Editable(false);
        model.Field(e => e.password);
        model.Field(e => e.ConfirmPassword);
        model.Field(p => p.Fakerole).DefaultValue(
        ViewData["defaultCategory"] as FakeRoleViewModel);
    })
    .PageSize(20)
    .Read(read => read.Action("EditingCustom_Read", "MyUser"))
    .Create(create => create.Action("EditingCustom_Create", "MyUser"))
    .Update(update => update.Action("EditingCustom_Update", "MyUser"))
    .Destroy(destroy => destroy.Action("EditingCustom_Destroy", "MyUser"))
  )
)


  <script type="text/javascript">
    function error_handler(e) {
    if (e.errors) {
        var message = "Errors:\n";
        $.each(e.errors, function (key, value) {
            if ('errors' in value) {
                $.each(value.errors, function() {
                    message += this + "\n";
                });
            }
        });
        alert(message);
    }
}
</script>
<script>
  OrderDetails_Error = function (args) {
    if (args.errors) {
        var grid = $("#orderDetailsGrid").data("kendoGrid");
        var validationTemplate = 
     kendo.template($("#orderDetailsValidationMessageTemplate").html());
        grid.one("dataBinding", function (e) {
            e.preventDefault();

            $.each(args.errors, function (propertyName) {
                // take the template and insert it into the placeholder
                var renderedTemplate = validationTemplate({ field: 
    propertyName, messages: this.errors });

   grid.editable.element.find(".errors").append(renderedTemplate);
              });
          });
       }
   };
</script>
<script type="text/x-kendo-template" 
 id="orderDetailsValidationMessageTemplate">
  # if (messages.length) { #
    <li>#=field#
        <ul>
            # for (var i = 0; i < messages.length; ++i) { #
                <li>#= messages[i] #</li>
            # } #
        </ul>
     </li>
   # } #
   </script>

  <script>
    function dataBound() {
        this.expandRow(this.tbody.find("tr.k-master-row").first());
    }

   </script>

它第一次显示所有数据，但是当重新加载信息时，不要在网格中显示数据！
