[Solved] Does GridEditMode.InCell supported in IE

[ken]

Hi All,
I'm currently using Telerik Grid and having issues with IE6 and IE8. There are multiple dropdownlist used in the grid however when I click on the Grid only one dropdown list shows. The same page works fine under IE9 and Firefox. Does any one know what I've done wrong? Thanks

Another question I have is if I have a master/detail view when adding new row. It seems all the columns are shifted. Does any one know how to fix that? Thanks

<%= Html.Telerik().Grid<Category>()
        .Name("Grid")
             .ToolBar(commands =>
             {
                 if(Model.IsAllowAdd)
                 {
                     commands.Insert();
                 }
                 commands.SubmitChanges();
                 commands.Position(GridToolBarPosition.Bottom);
             })

        .DataKeys(keys =>
         {
             keys.Add(p => p.Id);
         })
        .DataBinding(dataBinding =>
                dataBinding.Ajax()
                   .Select("Select", "ReferenceDataManagement")
                   .Update("UpdateCategory", "ReferenceDataManagement")

         )
         .Columns(columns =>
                      {
                          columns.Bound(col => col.Description).ReadOnly(!Model.IsAllowEditDescription);

                          columns.Bound(col => col.SchoolTypeDesc).Title(("School Type")).Width(100);

                          columns.Bound(col => col.FromGradeDesc).Title("From Grade").Width(100);

                          columns.Bound(col => col.ToGradeDesc).Title("To Grade").Width(100);
                          columns.Bound(col => col.IsActive).ReadOnly(!Model.IsAllowInactive).ClientTemplate("<input type='checkbox' name='IsActive' <#= IsActive? checked='checked' : '' #> />");
                      }

                  )

         .ClientEvents((events => events.OnSave("Grid_OnSave").OnDataBinding("Grid_onSelect").OnError("Grid_onError").OnSubmitChanges("Grid_onSubmit").OnDataBound("Grid_onDataBound")))
         .Editable(editing => editing.Mode(GridEditMode.InCell))
         .Pageable(page=>page.PageSize(20))

%>
