Hi all,

I am trying to make an HtmlHelper to create sub grids by passing an ISubGridBuilder which will contain the construction detail of my sub grid.


public interface ISubGridBuilder
   string ActionName { get; }
   string ControlerName { get; }
   void BuildColumns(GridColumnFactory<dynamic> gcf);
public static MvcHtmlString SubGridClient(this HtmlHelper html, ISubGridBuilder builder)
   return html.Kendo().Grid<dynamic>()
      .Navigatable(n => n.Enabled(true))
      .Selectable(s => s
      .Columns(gcf =>
      .DataSource(d => d
         .Model(m =>
            m.Field("ParentId", typeof(int));
         .Read(r => r.Action(builder.ActionName, builder.ControlerName, new {Id = "#=ParentId#" }))
      .Pageable(p => p
         .PageSizes(new[] { 3 })
      .Events(e => e.Change("function(e) { onChange(e)}"))

The problem is that at runtime I get a reference error:

VM17183:3 Uncaught ReferenceError: ParentId is not defined
    at Object.eval [as tmpl0] (eval at compile (kendo.all.js:234), <anonymous>:3:12352)
    at Object.eval (eval at compile (kendo.all.js:234), <anonymous>:3:185)
    at d (jquery.min.js:2)
    at HTMLAnchorElement.<anonymous> (kendo.all.js:64799)
    at HTMLTableElement.dispatch (jquery.min.js:3)
    at HTMLTableElement.r.handle (jquery.min.js:3)

How can I add the ParentId parameter on the routeValues for the controller call.

Thank you!

Hi Francis,

I have investigated the provided code snippets and I have noticed that the ParentID is a field that is available for the detail grid. However, the template is evaluated at the parent-level, therefore, the parent grid does not have such a field. Could you try alternating the declaration as follows:

         .Read(r => r.Action(builder.ActionName, builder.ControlerName, new {Id = "\\#=ParentId\\#" }))

Let me know in case the issue persists.
