[Solved] Issue in populating data in Combobox inside a Telerik Grid

[Gurunath]

Hi,

I have a combobox inside a Telerik grid. I am binding the data to the combobox OnRowDataBound event of the grid.

I am able to get the data in the call back function and bind it to the combobox. But  the data is not getting populated in the combobox and it looks like it is disabled.

Please let me know if I am missing anything here. 

@(Html.Telerik().Grid<DirectoryViewModel>()
            .Name("gridPartitions")
            .DataKeys(keys =>
            {
                keys.Add(k => k.Directory_ID);
            })
            .DataBinding(dataBinding =>
            {
                dataBinding.Ajax()
                    .Select("_Grid_SelectDirectories", "Request", new { Guid = @Model.Guid })
                    .Delete("_Grid_DeleteDirectories", "Request", new { Guid = @Model.Guid });
            })
                .Columns(columns =>
                {
                    columns.Bound(c => c.Directory_ID).Visible(false);
                    columns.Bound(c => c.Path).Width(100);
                   // columns.Bound(c => c.Access).Width(100);

                   columns.Bound(c => c.Directory_ID)
                   .Title("Permission Sets")
                   .ClientTemplate(

                   Html.Telerik().ComboBox()
                         .Name("<#= Directory_ID#>" + "_Combobox")
                         .Enable(false)
                         .AutoFill(true)
                         .ToHtmlString()
                     );

                    columns.Command(cmd =>
                    {
                        cmd.Delete().ButtonType(GridButtonType.BareImage);
                    });

                })

                      .ClientEvents(events =>
                     {
                         events.OnRowDataBound("AddAccess");

                      })

                    .Pageable()
                    .Sortable()
                    .Filterable()
                    )

function AddAccess(e) {


     var accessId = "#" + e.dataItem.Directory_ID + "_Combobox";

       url = '@Url.Action("GetAccess", "Request")';

         $.post(url, { nodeId: e.dataItem.Directory_ID, Guid: $("#Guid").val() },

           function (data) {


                  var combobox2 = $(accessId).data('tComboBox');

                  alert(data.length);
                  combobox2.close();
                  combobox2.dataBind(data);

              });

           }
