Question

I am getting below error at .DetailView line. How do I bind the detailview grid?

the best overloaded method match for
Telerik.web.mvc.ui.fluent.GridDetailsViewBuilder.ClientTemplate(string)
has some invalid arguments

<%= Html.Telerik().Grid<Models.Employee>()
        .Name("GridView1")
        .BindTo(Model)
        .Columns(columns =>
        {
            columns.Bound(o => o.EmpId).Width(100);
        })
         .DetailView(detailView => detailView.ClientTemplate(
                        Html.Telerik().Grid<Models.Employee>()
                             .Name("<#= EmpID #>")
%>

Answer 1

As the exception describes the ClientTemplate method expects a string. You can call the ToHtmlString() extension method at the end of the child Grid declaration.

Just like highlighted in this demo:
