[Mohamed]

I'm trying to create a master detail page but the data not displayed in the grid
 

this is my View:

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<IEnumerable<MvcApplication43.Models.MasterDetailViewModel>>" %>
 
<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
    test5
 
     <script type="text/javascript">
 
         function expandFirstRow(grid, row) {
             if (grid.$rows().index(row) == 0) {
 
                 grid.expandRow(row);
             }
         }
 
         function employees_onRowDataBound(e) {
             var grid = $(this).data('tGrid');
             expandFirstRow(grid, e.row);
         }
 
         function orders_onRowDataBound(e) {
             var grid = $(this).data('tGrid');
             expandFirstRow(grid, e.row);
         }
    </script>
</asp:Content>
 

 
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">

[GridAction]
public ActionResult _EmployeesHierarchyAjax()
{
var ListMatiere=(from u in new DB_26XEntities().Tbl_Raw_Material_Batch
orderby u.Lot_Number
select new MasterDetailViewModel
 
{

Lot_Number=u.Lot_Number,

});

return View(new GridModel(ListMatiere));
}
[AcceptVerbs(HttpVerbs.Post)]
[GridAction]
public ActionResult _OrdersForEmployeeHierarchyAjax(int RawMaterialResult_Id)
{
var MatResult = (from o in new DB_26XEntities().Tbl_Raw_Material_Result

select new MasterDetailViewModel
{
RawMaterialResult_Id=o.RawMaterialResult_Id,

});
return View(new GridModel(MatResult));
}
[AcceptVerbs(HttpVerbs.Post)]
[GridAction]
public ActionResult _OrderDetailsForOrderHierarchyAjax(int ResultDefinition_Nr)
{
var ResultDef =( from o in new DB_26XEntities().Tbl_ResultDefinition

return View(new GridModel(ResultDef));
}
