Hello,

is this code required for Client Edit Templates ( http://demos.telerik.com/aspnet-mvc/grid/clientedittemplates )?
My test works fine without this code.

<script type="text/javascript"
function onEdit(e) { 
    $(e.form).find('#Employee').data('tDropDownList').select(function (dataItem){ 
        return dataItem.Text == e.dataItem['Employee']; 
    }); 
}</script>

Regards,
Timo

Hello Timo,

If you need to select correct item in the DropDownList UI component, then you need to use this javascript code.

Hello,

this is strange.
i have modified your sample and it seems that it works.
where is the difference?

<asp:Content ID="Content1" ContentPlaceHolderID="MainContent" runat="server">
   <%= Html.Telerik().Grid<ClientEditableOrder>()
           .Name("Grid")
           .DataKeys(keys =>
           {
               keys.Add(o => o.OrderID);
           })
           .DataBinding(dataBinding =>
           {
               dataBinding.Ajax()
                   .Select("_ClientEditTemplate", "Grid")
                   .Update("_UpdateOrder", "Grid");
           })
           .Columns(columns =>
           {
               columns.Bound(o => o.OrderID).Width(100);
               columns.Bound(o => o.Employee).Width(230);
               columns.Bound(o => o.OrderDate).Width(150);
               columns.Bound(o => o.Freight).Width(220);
               columns.Command(commands => commands.Edit()).Title("Edit").Width(200);
           })
           .ClientEvents(events=>events.OnEdit("onEdit"))
           .Pageable()
    %>
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="HeadContent" runat="server">
<script type="text/javascript">
    function onEdit(e) {
    }
</script>
</asp:Content>

Timo

Hello Timo,

In Q2 SP1 of Telerik Components for ASP.NET MVC (version 2010.2.930) the code in OnEdit event handler is not required anymore in order to set correct selected item. Some improvements were made, which remove the need of this code.

Sincerely yours,

Hi,

  I just tried this new release, but it does not seems to work when I remove onEdit event.  I'm using a DropDownList in a subGrid (Hierarchical grid) and on Edt, the selected item is not selected.

Here is the code on my bound column
columns.Bound(u => u.Role).Width(100).
    ClientTemplate("<# if (Role) { #><#= Role.RoleName#> <#} else { #> none <# } #>");

Here is the code for EditorTemplate
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<IRoleSimple>" %>
  
<%= Html.DropDownList(null, new SelectList((IEnumerable)ViewData["RolesUsers"], "RoleId", "RoleName"))%>
<script type="text/javascript">
    // find the dropdown first
    var $dropdown = $('#Role');
    $('<option/>', { text: '<none>', value: -1 })
          .prependTo($dropdown);
    // find the table row (tr) which is being edited
    var $tr = $dropdown.closest('tr:has(form)');
  
    // get the grid client object
    var grid = $tr.closest('.t-grid').data('tGrid');
  
    // get the data item bound to this table row
    var dataItem = grid.dataItem($tr);
    // set the value of the dropdown to select the proper item
    $dropdown.val(dataItem.Role ? dataItem.Role.RoleId : -1);
</script>

Here is my Model class
[TypeConverter(typeof(UserConverter))]
public class RoleSimple : IRoleSimple
{
    public Guid RoleId { get; set; }
    public string RoleName { get; set; }
    public override string ToString()
    {
        return RoleName;
    }
}
[TypeConverter(typeof(UserConverter))]
public class UserConverter : TypeConverter
{
    public override bool CanConvertFrom(ITypeDescriptorContext context, Type sourceType)
    {
        return (sourceType == typeof(string)) ? true : base.CanConvertFrom(context, sourceType);
    }
}

I have a null reference exception in OnEdit for that line.
$(e.form).find('#Role') return an object, but
$(e.form).find('#Role').data('tDropDownList')
return null

$(e.form).find('#Role').data('tDropDownList')


Thank you

Hi,
I'm facing the same issue as "returning 'null' in the 

$(e.form).find('#Roles').data('tDropDownList')

I included the "telerik.list.min.js" by my own.
I've also tried the hotfix (v 2010.3.1111), unfortunately the problem is still there.
Anybody got new idea? Thanks in advance.

Just downloaded the latest version 2010.3.1110 in OFFICIAL download page (NOT 2010.3.1111 attached in the other forum post), and included those js files manually via ScriptRegistrar in Site.Master, and it works fine now:

<%= Html.Telerik().ScriptRegistrar()
                .DefaultGroup(group => group.DefaultPath("~/Scripts/2010.3.1110/")
                                            .Add("jquery-1.4.3.min.js")
                                                  ......
                                            .Add("telerik.list.min.js")
                                                  ......
                                              .Compress(true))
 %>

I don't know if it can help, but here is my OnEdit code

function OnEdit(e) {
    var $dropdown = $(e.form).find('#Role');
    $('<option/>', { text: '<none>', value: -1 })
  .prependTo($dropdown);
    $dropdown.val(e.dataItem.Role.RoleId);
}

Hope this help
Steve
