Group Paging is not working as expected when the Kendo UI Grid is populated from data deserialized from a file and multiple groups are defined.
Using the UI for ASP.NET Core Grid, populate it with a file, set GroupPaging to true, add more than one group, and set the default serialization:
builder.Services.AddControllersWithViews() .AddJsonOptions(options => options.JsonSerializerOptions.PropertyNamingPolicy = null);
@(Html.Kendo().Grid<MyViewModel>() .Name("grid") .Groupable() .Scrollable(s => s.Virtual(true)) .DataSource(dataSource => dataSource .Ajax() .GroupPaging(true) .PageSize(50) .Read("ReadFromFile", "HomeController") .Group(x => { x.Add(y => y.Group1); x.Add(y => y.Group2); }) ) //... )
With multiple groups, the follow error message will appear:

Server GroupPaging should work as expected with multiple groups and the default serialization that is delivered with ASP.NET Core. An example would be this live demo.
Use the Newtonsoft library to set the serialization options for the application:
builder.Services.AddControllersWithViews() .AddNewtonsoftJson(options => options.SerializerSettings.ContractResolver = new Newtonsoft.Json.Serialization.DefaultContractResolver());
