Grid data is undefined after upgrade to Core 3.2

[Brad]

I recently upgraded my project to ASP NET Core 3.2 and now my grids are returning undefined.  I've found a couple threads about this, but nothing that has worked for me so far.  I have an enumerable defined object that I'm creating in my AJAX LoadData method to load my data and returning.  What am I doing wrong?

 

index.cshtml

<ejs-grid id="Grid" allowPaging="true" allowSorting="true" allowFiltering="true">
    <e-data-manager url="/Routes/LoadData" updateUrl="/Routes/UpdateData" adaptor="UrlAdaptor"></e-data-manager>
    <e-grid-columns>
        <e-grid-column field="Name" headerText="Name" allowSorting="true"></e-grid-column>
        <e-grid-column field="Frequency.Name" headerText="Frequency" type="string"></e-grid-column>
        <e-grid-column field="DayOfWeek.Name" headerText="Day" type="string"></e-grid-column>
        <e-grid-column field="TimeOfDay.TimeString" headerText="Time"></e-grid-column>
        <e-grid-column field="RouteId" headerText="" template="#edittemplate"></e-grid-column>
    </e-grid-columns>
</ejs-grid>

<script id="edittemplate" type="text/x-template">
    <div>
        <a rel='nofollow' href="/Routes/Edit/${RouteId}">Edit</a>&nbsp;|&nbsp;
        <a rel='nofollow' href="/Routes/Details/${RouteId}">Details</a>&nbsp;|&nbsp;
        <a rel='nofollow' href="/Routes/Delete/${RouteId}">Delete</a>&nbsp;
    </div>
</script>

 

 

Controller

        public IActionResult LoadData([FromBody]DataManagerRequest dm)
        {
            var sa = new JsonSerializerSettings();
            IEnumerable<Route> DataSource = _context.Route
                .Include(r => r.DayOfWeek)
                .Include(r => r.Frequency)
                .Include(r => r.TimeOfDay)
                .ToList();
            DataOperations operation = new DataOperations();
            if (dm.Search != null && dm.Search.Count > 0)
            {
                DataSource = operation.PerformSearching(DataSource, dm.Search);  //Search
            }
            if (dm.Sorted != null && dm.Sorted.Count > 0) //Sorting
            {
                DataSource = operation.PerformSorting(DataSource, dm.Sorted);
            }
            if (dm.Where != null && dm.Where.Count > 0) //Filtering
            {
                DataSource = operation.PerformFiltering(DataSource, dm.Where, dm.Where[0].Operator);
            }
            int count = DataSource.Cast<Route>().Count();
            if (dm.Skip != 0)
            {
                DataSource = operation.PerformSkip(DataSource, dm.Skip);         //Paging
            }
            if (dm.Take != 0)
            {
                DataSource = operation.PerformTake(DataSource, dm.Take);
            }

            return Json(new { result = DataSource, count = _context.Route.Count() });
        }

Hi, Brad,

Thank you for providing the grid definition which appears to be not a Kendo UI Grid but a SyncFusion one.

Therefore, it is best to check with SyncFusion what could be the reason for the grids not working.

Kind Regards,
