I want to implement the master detail view functionality in telerik's mvc webgrid. The problem is that while the first row comes expanded by default, i cannot collapse the first row and i cannot expand the successive rows to view the data. What do i do to achieve the functionality? The code is:

@{
    
     Html.Telerik().Grid(this.Model)
                   .Name("grdPersonView")
                   .Columns(columns =>
                       {
                           columns.Bound(p => p.id);
                           columns.Bound(p => p.age);
                           columns.Bound(p => p.name);
                       })
                   .DetailView(detailview => detailview.Template(e =>
                       {
                       
                           Html.Telerik().Grid(e.GetPersons())
                               .Name("Subgrid")
                               .Columns(column =>
                                   {
                                       column.Bound(p => p.name);
                                       column.Bound(p => p.age);
                                   })
                                   .Pageable(pager => pager.PageSize(2))
                                   .Render();
                       }))
                   .RowAction(row =>
                       {
                           if (row.Index == 0)
                           {
                               row.DetailRow.Expanded = true;
                           }                        
                       })
                   .Pageable(pager => pager.PageSize(20))
                   .Sortable(sorting =>
                       {
                           sorting.SortMode(GridSortMode.MultipleColumn);
                           sorting.OrderBy(sortOrder => sortOrder.Add(p => p.id));
                       }
                           )
                           .Render();
             
    }

Be sure to use different names for your master and detail grids.

Of course, if I would have looked at your source before posting, I would have quickly seen that you did name them differently :).

Hi,

 The sample posted here has one issue - all subgrids will have the same name which is a problem. Components need to have unique name so they can be identified and initialized client-side. This is why our example is appending the parent id in the name of the subgrids:

.DetailView(detailView => detailView.Template(e =>
        {
            %>
                <% Html.Telerik().Grid(e.Orders)
                       .Name(
"Orders_" + e.EmployeeID)

I hope this helps,
