Pass hidden fields in Telerik grid row - asp.net-core

Question

I use Telerik grid in my asp.net core application.
I have a list of Orders, I need to bind some fields (like CreatedBy, by eg.) to be hidded, in order to get them when the user updates them.
I saw similar question without an answer.
my Code
#(Html.Kendo()
.Grid(Model)
.Name("Orders")
.Columns(columns =>
{
columns.Bound(c => c.Name).Width(190);
columns.Bound(c => c.CreatedById).Hidden();
columns.Bound(c => c.ModifiedById).Hidden();
columns.Command(command => { command.Destroy(); }).Width(100);
})
.Editable(editable => editable.Mode(GridEditMode.InCell))
.DataSource(dataSource => dataSource
.Ajax()
.Batch(true)
.PageSize(20)
.ServerOperation(false)
.Events(events => events.Error("error_handler"))
.Model(model => {
model.Id(s => s.Id);
})
.Create(update => update.Action("BatchCreate", "Orders"))
.Read(read => read.Action("BatchRead", "Orders"))
.Update(update => update.Action("BatchUpdate", "Orders"))
.Destroy(update => update.Action("BatchDestroy", "Orders"))
)
)

Answer 1

Finally, solved it by adding the hidden fields to the datasource model:
.Columns(columns =>
{
columns.Bound(c => c.Name).Width(190); // visible
columns.Bound(c => c.HiddenId).Hidden();
columns.Bound(c => c.HiddenOtherFiled).Hidden();
})
.DataSource(dataSource => dataSource
.Ajax()
.ServerOperation(false)
.Events(events => events.Error("error_handler"))
.Model(model =>
{
model.Id(s => s.Id);
model.Field(s => s.HiddenId);
model.Field(s => s.HiddenOtherFiled);
})
