title: Kendo Tabstrip loading Grid with .Content works, .LoadContentFrom doesn't
body: <p>I have a tabstrip loading a grid in 2 different tabs (the same grid, the same data).</p>
  
  <pre><code>    @(Html.Kendo().TabStrip()
      .Name("tabstrip")
      .Items(tabstrip =&gt;
      {     
          tabstrip.Add().Text("Cycle Summary")
              .Content(@&lt;text&gt;@Html.Action("VQCycleSummary", "Sessions", new { id = Model.ID })&lt;/text&gt;).Selected(true);
          tabstrip.Add().Text("Cycle Summary2")
              .LoadContentFrom("VQCycleSummary", "Sessions", new { id = Model.ID });
  
  
      })
  )
  </code></pre>
  
  <p>The Grid:</p>
  
  <pre><code>@(Html.Kendo().Grid(Model)
    .Name("cycleGrid")
    .DataSource(ds =&gt; ds
        .Ajax()
        .Read(read =&gt; read.Action("VqCyclesSummary_Read", "Sessions", new {sessionId = ViewBag.SessionID}))
        .PageSize(100)
    )
    .Columns(columns =&gt;
    {
        columns.Bound(c =&gt; c.TimeStampUTC).Format("{0: MM/dd/yyyy h:mm:ss tt}").Width(180);
  
        for (int i = 1; i &lt;= ((int) ViewBag.MaxChannelNumber); ++i)
        {
            columns.Bound(string.Format("Channel{0}_DL", i)).Format("{0:N5}");
        }
        for (int i = 1; i &lt;= ((int) ViewBag.MaxChannelNumber); ++i)
        {
            columns.Bound(string.Format("Channel{0}_UL", i)).Format("{0:N5}");
        }
        columns.Bound(c =&gt; c.GPS_Lat).Format("{0:N5}");
        columns.Bound(c =&gt; c.GPS_Long).Format("{0:N5}");
    })
    .Filterable()
    .Sortable()
    .Scrollable(c =&gt; c.Height(500)).Scrollable(c =&gt; c.Virtual(true)))

  <p>Controller:</p>
  
  <pre><code>public ActionResult VQCycleSummary(long id)
      {
      using (var context = new Entities())
      {
          short? max = context.TestDevices.Where(td =&gt; td.SessionID == id).Max(td =&gt; td.ChannelNumber);
  
  
          ViewBag.MaxChannelNumber = max.HasValue ? (int) max + 1 : 0;
          ViewBag.SessionID = id;
          return PartialView("VqCycleSummary");
      }
  }
  
  public ActionResult VqCyclesSummary_Read([DataSourceRequest] DataSourceRequest request, int sessionId)
  {
      using (var context = new Entities())
      {
          var cycles = //get data
  
          DataSourceResult result = cycles.ToDataSourceResult(request);
  
          return Json(result);
      }
  }
  </code></pre>
  
  <p>I see the data displayed properly on the first grid, but not the second. I do see the data getting returned from the controller for both grids. The columns are getting created for the second grid, but the rows of actual data aren't displaying.</p>
