    The grid definition in mvc core chtml



    .Columns(columns => { columns.Bound(p => p.CatalogNumber); columns.Bound(p => p.UsageCode).Width(150); })

    Pageable() .Sortable() .Filterable()

    .DataSource(dataSource => dataSource

           .Ajax() .PageSize(20)

         .Read(read => read.Action("ChangeOrder_Read", "Naco"))

    ).Deferred() )  

    Here is my data returned from ajax call

    { "Data": [ { "CatalogNumber": "Catalog 12345", "UsageCode": "Usage Code 1" }, { "CatalogNumber": "Catalog 8234758", "UsageCode": "Usage Code 2" } ], "Total": 0, "AggregateResults": null, "Errors": null }

    all events are triggering on grid, but no data binding happening.  Here is my entry in startup


    services.AddControllersWithViews(options => { options.Filters.Add(new AbpAutoValidateAntiforgeryTokenAttribute()); })

    .AddJsonOptions(options => { options.JsonSerializerOptions.PropertyNameCaseInsensitive = true; options.JsonSerializerOptions.PropertyNamingPolicy = null; }) 

    Any help greatly appreciated.
    Thanks V

    Hello Prakash,

    Thank you for the code snippet. 

    On my side, the data is binding correctly if I remove the Deffered() method, which will suppress the immediate rendering of the script statements. Attached you will find a project for reference based on the provided code snippet. If removing the Deffered method does not resolve the issue, could you please modify the project to reproduce the issue? I will then debug it and happily assist you.

    Looking forward to your reply.
