Hi Hristo,

thanks for your help. In the meantime I did the following:

1 Removed the reference

<script src="~/lib/jquery/dist/jquery.js"></script>

2 Added the reference

@inject Microsoft.ApplicationInsights.Extensibility.TelemetryConfiguration TelemetryConfiguration
in the _ViewImports.cshtml after having added the nuget package Microsoft.ApplicationInsights version 2.7.2

Now I get an ugly error

InvalidOperationException: No service for type 'Microsoft.ApplicationInsights.Extensibility.TelemetryConfiguration' has been registered.

on starting the application (asp.mvc core 2.1) ..?

Second: before I added the @inject line in _ViewImports.cshtml
on debugging the page at

<jqx-grid theme="@ViewData["Theme"]" sortable="true" filterable="true" height="500" width="850" source="Model">

the “Model” contain a List of IEnumerable<Person> passed by the Controller

    public class GridController : Controller
    {
        List<Person> data;

        [HttpGet]
        public ViewResult List()
        {
            PersonService ps = new PersonService();
            data = ps.GetPersons();
            return View(data);
        }

    }

As if the datasource is Ok?
If I remove the source=”Model” Attribute in <jqx-grid an emtpy grid is display, otherwise there is no grid in the page..
That’s still my issue.

In all samples I saw about the jqgrid the object type passed from the controller ist a “List<T>”, seems to be right ?
My question now: Is the error “TypeError: $.jqx is undefined” just due to the missing component TelemetryConfiguration
or do I have a mix of two errors
1. TelemetryConfiguration missing AND 2. any object type mismatch Grid expects another datasource type (not an List<T> ???)
in other word if the first error would be fixed the TypeError would be resolved ?? Then the issue would now be reduced to the InvalidOperationException ?? Any help is appreciated…

the error “TypeError: $.jqx is undefined” appear although the declarations in the header:

<script src=”~/jqwidgets/jqxbuttons.js”></script>
<script src=”~/jqwidgets/jqx-all.js”></script>
<script src=”~/jqwidgets/jqxgrid.columnsresize.js”></script>
<script src=”~/jqwidgets/jqxbuttons.js”></script>
<script src=”~/jqwidgets/jqxscrollbar.js”></script>
<script src=”~/jqwidgets/jqxgrid.js”></script>
<script src=”~/jqwidgets/jqxgrid.edit.js”></script>
<script src=”~/jqwidgets/jqxgrid.columnsresize.js”></script>
<script src=”~/jqwidgets/jqxgrid.filter.js”></script>
<script src=”~/jqwidgets/jqxgrid.selection.js”></script>
<script src=”~/jqwidgets/jqxgrid.sort.js”></script>

the recommendation in the post

https://www.jqwidgets.com/community/topic/typeerror-a-jqx-_jqxgrid-is-undefined/

doesn’t help ..?
