Kendo UI Window on grid button click does not open

Question

im working on an MVC Kendo Ui project and i'm having the following problem:

I have an editable kendo grid with a custom edit button wich opens a partial view on a kendo window wich acts like an "editor template". This seems to work fine first time but if i close the window and try to edit another item or even the same just does not work. I think that when i close the window this eliminate the elemment from the DOM but can't figure it out how to fix it. Here is some code:

@(Html.Kendo().Grid(Model)
      .Name("gridUbicaciones")
      .Columns(col =>
          {
              col.Bound(x => x.UbicacionId);
              col.Bound(x => x.Nombre);
              col.Bound(x => x.Latitud);
              col.Bound(x => x.Longitud);
              col.Bound(x => x.Altitud);
              col.Bound(x => x.Comentario);
              col.Command(cmd =>
                  {
                      cmd.Custom("Editar").Click("editItem");                     
                      cmd.Destroy().Text("Borrar");
                  }).Width(210).HtmlAttributes(new {style = "text-align:center;"});
          })
      .ToolBar(toolbar => toolbar.Create().Text("Agregar") )
      .Pageable()
      .Sortable()
      .Filterable()
      .DataSource(dsource => dsource
                                 .Ajax()
                                 .PageSize(8)
                                 .ServerOperation(false)
                                 .Model(model => 
                                     {
                                         model.Id(x => x.UbicacionId);
                                         model.Field(x => x.UbicacionId).Editable(false);
                                     })
                                 .Read(read => read.Action("Ubicaciones_Read", "Home").Type(HttpVerbs.Post))
                                 .Destroy(destroy => destroy.Action("Ubicaciones_Destroy", "Home"))
                                 .Update(update => update.Action("Ubicaciones_Update", "Home"))
                                 .Create(create => create.Action("Ubicaciones_Create", "Home"))
      ))
<div id="kendoWindowPopUp"></div>

JAVASCRIPT :

function editItem(e) {
    e.preventDefault();
    var dataItem = this.dataItem($(e.currentTarget).closest("tr"));
    if ($("#kendoWindowPopUp") == undefined)
        $("divUbicaciones").append("<div id=\"kendoWindowPopUp\"></div>");
    var windowObject = $("#kendoWindowPopUp").kendoWindow({
        resizable: false,
        modal: true,
        refresh: function () { this.center();},
        onClose: function () {

            windowObject.destroy();
            alert('hi close');// THIS CODE DOES NOT RUN
        }

    })
    .data("kendoWindow");



    windowObject.refresh({
        url: "/Home/EditorUbicacion?UbicacionId=" + dataItem.UbicacionId

    });
        windowObject.open();

}

I get the following js error:

Uncaught TypeError: Object [object Object] has no method 'kendoWindow'

Thanks in Advance!

Your problem lies in your editItem(), onClose does not eliminate the element from DOM by default, you are doing it deliberately. To refresh the window content, make some checks as:

function editItem(e) {
        e.preventDefault();
        var dataItem = this.dataItem($(e.currentTarget).closest("tr"));

        // Window variable
        var wnd = $("#kendoWindowPopUp");
        if (!wnd.data("kendoWindow")) {
            // initialized on first call and successive calls will reuse this object
            wnd.kendoWindow({
                width: "600px",
                title: "title",
                actions: [
                    "refresh",
                    "Minimize",
                    "Maximize",
                    "Close"
                ],
                resizable: false,
                modal: true,
                visible: false
                // Leave all events with their default behavior                
            });
        }

        var windowObject = wnd.data("kendoWindow");
        windowObject.refresh({
            url: "/Home/EditorUbicacion?UbicacionId=" + dataItem.UbicacionId
        });
        windowObject.open().center();
    }

The answer is in the comments. Adding it here for those like me hitting this through google :). This issue is usually caused when the page loaded via AJAX contains a script reference to jQuery. When jQuery is reinitialized, all jQuery-based data attributes are cleared, including the data(kendoWidget) attribute that holds the Kendo UI widget object.

1. Please make sure that the Window does not load a duplicate jQuery instance on the page.

2. Use 'iframe'

   $("#dialog").kendoWindow({
      // load complete page...
      content: "/foo",
      // ... and show it in an iframe
      iframe: true
   });
