Hi,

I tried ajax code.

in the view I tried the following code. first I wanted to render some data without passing a spcific model to view

@{
    ViewBag.Title = "Test";
}

<h2>Test</h2>
@(Html.Telerik().Grid<myOffice.ViewModels.ActivityViewModel>()
    .Name("Employees")
    .Columns(columns =>
    {
        columns.Bound(e => e.Id).Width(140);
        columns.Bound(e => e.Employee).Width(140);
        columns.Bound(e => e.Embassy).Width(200);
        columns.Bound(e => e.Bank).Width(200);

    })

    .DataBinding(dataBinding => dataBinding.Ajax().Select("_EmployeesHierarchyAjax", "Grid"))
    .Pageable(paging => paging.PageSize(5))
    .Scrollable(scrolling => scrolling.Height(580))
    .Sortable()
)

<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> 

but then I get the grid without data.
if you want any more code deal with this please let me know.

hi another problem is contoller.

[GridAction]
        public ActionResult _EmployeesHierarchyAjax()
        {
            var employees = from e in new  kesofficeEntities().activities
                            orderby e.id
                            select new ActivityViewModel
                            {
                                Id=e.id,
                                Employee=(int)e.employee,
                                Embassy=(int)e.embassy,
                                Bank=(decimal)e.bank
                            };

            return View(new GridModel(employees));
        }

in the code they passe new GridModel(employees)
but this object is not catch in the view.
then how data is catch?

Make sure you have the latest versions of jquery, jquery.validate, and modernizr if you're using them. Some of the older versions will cause telerik to break.

in the code they passe new GridModel(employees)
but this object is not catch in the view.
then how data is catch

When the action is marked with the GridAction attribute it returns the GridModel as a JSON object that is used to update the contents of the telerik grid. Since you are using Ajax databinding this is done with an Ajax call to the server.

thx Cherryhomesj for ur reply, I checked the telerick script and content folders, they have folder with name 2012.2.607. Therefore, I can say I have installed latest jquery and css.I downloaded newly telerik plugins 3 weeks ago.

Can you also post the code for your layout page, should be int eh views/shared folder. Also, just to be sure, the name of your controller is GridController?

DataBinding(dataBinding => dataBinding.Ajax().Select("_EmployeesHierarchyAjax", "Grid"))

The "Grid" in that line is specifying the name of the controller to look for the action in.
