[Solved] Grid RowAction not working properly

[Abdulmenan]

I was using Telerik Grid with RowAction method to increment an index during binding. the code is as follows

<%       int x = -1;
             Html.Telerik()
                   .Grid(Model.Orders)
                   .Name("Ord")
                   .Columns(columns =>
                       {
                           columns.Template(o =>
                           {%>
    <%= Html.CheckBox("Model.Orders[" + x + "].IsSelected", o.IsSelected)%>
    <%}).Width(10);
                           columns.Bound(o => o.ID).Title("Student Number").Width(80);
                           columns.Bound(o => o.Name).Title("First Name").Width(150);

                       }).RowAction(row =>
             {
                 x++;
             })

 .Sortable()
.Render(); %>

public class CustomerViewModel
    {
        public List<Order> Orders { get; set; }

    }
    public class Order
    {
        public int ID { get; set; }
        public String Name { get; set; }
        public Boolean IsSelected { get; set; }

    }

    public class HomeController : Controller
    {
        public ActionResult Index()
        {
            CustomerViewModel model = new CustomerViewModel()
            {
                Orders = new List<Order> {

                new Order() { ID = 1, Name = "Banana" }, new Order() { ID = 2, Name = "Onion" }, new Order(){ID=3,Name="Car"} }
            };

            return View(model);
        }
    }

public class CustomerViewModel

    {

        public List<Order> Orders { get; set; }

    }

    public class Order

    {

        public int ID { get; set; }

        public String Name { get; set; }

        public Boolean IsSelected { get; set; }

    }

   

    public class HomeController : Controller

    {

        public ActionResult Index()

        {

            CustomerViewModel model = new CustomerViewModel()

            {

                Orders = new List<Order> { 

                

                new Order() { ID = 1, Name = "Banana" }, new Order() { ID = 2, Name = "Onion" } }

            };

            return View(model);

        }

    }

in the renderd Html all check boxes are converted to input controls with same ID.  which is the last row's ID.

<input id="Model_Orders_2__IsSelected" name="Model.Orders[2].IsSelected" type="checkbox" value="true" /><

it was working fine in the previous version of Telerik extension, this error comes when i upgrade from v2009 to the V2010.

can any one help me to fix this

Hi Abdulmenan,

Indeed we changed the way templates were rendered which seems to have affected your code. After further research I think it is the problem described in this stackoverflow thread. The solution is rather simple:

1. Remove the RowAction delegate - you don't need it
2. Render the checkbox like this:
   <%= Html.CheckBox("Model.Orders[" + x++ + "].IsSelected", o.IsSelected)%>
