Telerik MVC 3 Grid 3 level master detail - asp.net-mvc-3

Question

Here's my grid
Class year > Course > Student
Problem
1. How can I get the key from the first grid? (classyearID from classyear grid?)
The reason I need it because I have more than 5 class years, but only have 2 courses. so basically those two coursse will exist in every class year. and since I cant get the class yearID, students are reappearing on each class year, please help
check my view below:
#(Html.Telerik().Grid<ClassYear>().HtmlAttributes(new { style = "width: 100%" })
.Name("grdClassYear")
.DataBinding(binding => binding.Ajax()
.Select("GetClassYears", "Home"))
.DataKeys(keys => keys
.Add(o => o.ClassYearID)
.RouteKey("classyearID"))
.Columns(cols =>
{
cols.Bound(c => c.ClassYearDate);
cols.Bound(c => c.Name);
})
.DetailView(course => course.ClientTemplate(
Html.Telerik().Grid<Course>()
.Name("grdCourse_<#= ClassYearID #>")
.DataBinding(dataBinding => dataBinding.Ajax()
.Select("GetCourses", "Home"))
.DataKeys(keys => keys.Add(o => o.CourseID))
.Columns(cols =>
{
cols.Bound(c => c.CourseName);
cols.Bound(c => c.Description);
})
.DetailView(stu => stu.ClientTemplate(
Html.Telerik().Grid<Student>()
.Name("grdStudent_<#= CourseID #>")
.DataBinding(dataBinding => dataBinding.Ajax()
.Select("GetStudentsA", "Home", new { classyearID = "<#= ClassYearID #>", courseID = "<#= CourseID #>" })))
.DataKeys(keys => keys.Add(o => o.PersonID))
.Columns(cols =>
{
cols.Bound(c => c.PersonID).ReadOnly().Hidden();
cols.Bound(c => c.MidshipmenNumber);
cols.Bound(c => c.LastName);
cols.Bound(c => c.FirstName);
})
.Sortable()
.ToHtmlString()
))
Thanks

i am not sure, whether this has been resolved yet or not. but just wants to give answer on it, so it might help somebody.
make your detail grid name as example,
.Name("grdStudent_<#= ClassYearID #>_<#= CourseID #>")
basically, each Detail View name should be unique.
