    <p>I have two Kendo grid definitions, in partial views, that are exactly the same save for the partial view model and the grid item model. Only one of then gives me the JavaScript console error 'Cannot read property 'dataSource' of undefined' on the line of code:</p> <pre><code>$("#index-grid").data("kendoGrid").dataSource.bind("change", function (e) {...}) </code></pre> <p>and the other does not. It is not <code>dataSource</code> that is undefined, but <code>$("#index-grid").data("kendoGrid")</code>. Yet, in the other identical grid, I do not get this error. Can the data provided to the data source perhaps invalidate the grid itself? The grid definitions look like this:</p> <pre><code>@model TerminalIndexModel @using Kendo.Mvc.UI @using ParkPay.Helm.ViewModels @(Html.Kendo().Grid&lt;TerminalIndexItem&gt;() .Name("index-grid") .Columns(columns =&gt; { columns.Bound(p =&gt; p.Name); columns.Template(@&lt;text&gt;&lt;/text&gt;).ClientTemplate("&lt;input type='checkbox' #= IsActive ? checked='checked':'' # class='chkbx' /&gt;").Title("Active").Width(70); columns.Bound(p =&gt; p.Remarks); columns.Command(cmd =&gt; cmd.Destroy()).Width(80); }) .ToolBar(toolbar =&gt; { toolbar.Create(); toolbar.Save(); }) .HtmlAttributes(new { style = "height: 480px;"}) .Editable(editable =&gt; editable.Mode(GridEditMode.InCell)) .Filterable() .Pageable() .Scrollable() .Sortable() .Resizable(resize =&gt; resize.Columns(true)) .Reorderable(reorder =&gt; reorder.Columns(true)) .DataSource(dataSource =&gt; dataSource .Ajax() .ServerOperation(false) .Batch(true) .PageSize(20) .Events(events =&gt; events.Error("kendoGridErrorHandler")) .Model(model =&gt; model.Id(p =&gt; p.Id)) .Read(read =&gt; read.Action("Read", "Terminal")) .Update(update =&gt; update.Action("BatchUpdate", "Terminal")) .Create(create =&gt; create.Action("BatchCreate", "Terminal")) .Destroy(destroy =&gt; destroy.Action("BatchDelete", "Terminal")) ) ) </code></pre> <p>with the only difference being <code>TerminalIndexItem</code> versus <code>LocationIndexItem' and and</code>TerminalIndexModel<code>versus</code>LocationIndexModel<code>, and of course the controller names in the CRUD definitions,</code>Terminal<code>versus</code>Location`. I am at my wit's end finding a difference between the two grids.</p>

    3. COIs there any difference in when the two grids get displayed in relation to when the problematic line executes? Meaning, is it possible that for the grid that works, it is already initialized when the line executes, and for the problematic grid it is not? Also, the grids with the same name aren't used on the same page at the same time, correct?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
