How can I get the parent ID when I trying to add new subelement? See attachment.

Sub-grid code template looks like below:
<script id="template" type="text/kendo-tmpl">
@(Html.Kendo().Grid<ZakresViewModel>()
.Name("podzakresy#=IdZakres#")
.Editable(editable => editable.Mode(GridEditMode.PopUp))
.ToolBar(toolbar =>
{
    toolbar.Create().Text("<span class=\"fa fa-plus\"></span> " + SettingsStrings.DodajNowyPodzakres).HtmlAttributes(new { @class = "btn btn-warning", idZakresNadrzedny = "#=IdZakres#" });
})
.Columns(columns =>
{
    columns.Bound(c => c.Numer).Width(80).Title(SharedStrings.Numer);
    columns.Bound(c => c.Nazwa).Title(SharedStrings.Nazwa);
    columns.Command(command => command.Edit().UpdateText(SharedStrings.Zapisz).CancelText(SharedStrings.Anuluj).Text(SharedStrings.Edytuj)).Width(100);
    columns.Command(command => command.Destroy().Text(SharedStrings.Usun)).Width(100);
})
.DataSource(dataSource => dataSource
    .Ajax()
    .PageSize(10)
    .Model(model => { model.Id(p => p.IdZakres); })
    .Read(read => read.Action("GridPodzakresy_Read", "Settings", new { IdZakresNadrzedny = "#=IdZakres#" }))
                        .Create(create => create.Action("GridPodzakresy_PopupCreate", "Settings", new { IdZakresNadrzedny = "#=IdZakres#" }))
                        .Update(update => update.Action("GridZakresy_PopupUpdate", "Settings"))
                        .Destroy(delete => delete.Action("GridZakresy_PopupDestroy", "Settings"))
)
.Pageable()
.Selectable(selectable => selectable.Mode(GridSelectionMode.Single))
.Sortable()
.ToClientTemplate()
)
</script>


Main grid code looks like below:
@(Html.Kendo().Grid<ZakresViewModel>()
.Name("grid-zakresy")
.HtmlAttributes(new { style = "height:100%; cursor:default" })
.ClientDetailTemplateId("template")
.Editable(editable => editable.Mode(GridEditMode.PopUp))
.ToolBar(toolbar => toolbar.Create().Text("<span class=\"fa fa-plus\"></span> " + SettingsStrings.DodajNowyZakres).HtmlAttributes(new { @class = "btn btn-primary" }))
.Columns(columns =>
{
    columns.Bound(c => c.IdKontrakt).Visible(false).Filterable(false);
    columns.Bound(c => c.IdZakres).Visible(false).Filterable(false);
    columns.Bound(c => c.IdZakresNadrzedny).Visible(false).Filterable(false);
    columns.Bound(c => c.Numer).Width(80).Title(SharedStrings.Numer);
    columns.Bound(c => c.Nazwa).Title(SharedStrings.Nazwa);
    columns.Command(command => command.Edit().UpdateText(SharedStrings.Zapisz).CancelText(SharedStrings.Anuluj).Text(SharedStrings.Edytuj)).Width(100);
    columns.Command(command => command.Destroy().Text(SharedStrings.Usun)).Width(100);
})
.Pageable(pageable => pageable.Refresh(true).ButtonCount(3))
.Sortable(s => { s.AllowUnsort(true); s.SortMode(GridSortMode.MultipleColumn); })
.Scrollable(scr => { scr.Height("100%"); scr.Enabled(false); })
.Selectable(selectable => selectable.Mode(GridSelectionMode.Single))
.DataSource(dataSource => dataSource
    .Ajax()
    .PageSize(10)
    .Model(model => { model.Id(p => p.IdZakres); })
    .Read(read => read.Action("GridZakresy_Read", "Settings", new { IdKontrakt = Model.IdKontrakt }))
    .Create(create => create.Action("GridZakresy_PopupCreate", "Settings"))
    .Update(update => update.Action("GridZakresy_PopupUpdate", "Settings"))
    .Destroy(delete => delete.Action("GridZakresy_PopupDestroy", "Settings"))
)
)

Action in controller when I trying to create new element. At this action I need parent ID.
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult GridPodzakresy_PopupCreate([DataSourceRequest] DataSourceRequest request, ZakresViewModel zakres)
{
    if (zakres != null && ModelState.IsValid)
    {
        //some code
    }
 
    return Json(new[] { zakres }.ToDataSourceResult(request, ModelState));
}

Thanks in advance

Hi Artur,

The easiest way will be to pass is as a URL parameter. I noticed that you have already added it to the create action. Then you should change the action method in order to get it mapped as a parameter, something similar to the following:

public ActionResult GridPodzakresy_PopupCreate([DataSourceRequest] DataSourceRequest request, ZakresViewModel zakres, int IdZakresNadrzedny)
{
   /*....*/
}

Note that if the parameter name matches the property name of the model, it may not be bound correctly. In this case you should change the name of the parameter.
