Grid with dynamic ajax binding and Column filter issue

[Ravindra]

Hi,
I'm trying to use the MVC grid with dynamic type and Ajax binding. it is working fine until i enable the filterable option enabled in the grid.
When i enable the filter option in the grid, the default filter dropdown has no operators populated in it. below is the code that i have been using and attached a sample screenshot of how the default filter is looking like

Html.Telerik().Grid<dynamic>()
    .Name("Grid")
    .Columns(columns =>
    {
        if (context.Columns != null)
        {
            foreach (ColumnSettings item in context.Columns)
            {
                columns.Bound(item.Key).Title(item.Header).Filterable(item.Filterble).Sortable(item.Sortable);
            }
        }
        else
        {
            columns.AutoGenerate(true);
        }
    })
    .DataBinding(dataBinding => dataBinding.Ajax().Select("_AjaxBinding", "Grid"))
    .Pageable(paging => paging.Enabled(config.IsPagable))
    .Sortable(sorting => sorting.Enabled(config.IsSortable))
    .Filterable(filter => filter.Enabled(config.IsFilterable))
    .Groupable(grouping => grouping.Enabled(config.IsGroupable))

in the above code, you will see 'config' instance. this i'm using it for some configuration purpose. please see the attachment and help me resolving this issue

Thanks in advance!

This got resolved by specifying the column type as below

columns.Bound(typeof(decimal), Key)

Hi alonav,

 Try this instead:

keys.Add(c => c.UnitId)

Server Error in '/' Application.

What about the other issue- empty popup edit window?

Hi alonav,

 You can check this code library project which shows how to use editing in grid bound to dynamic model. If this doesn't help I would ask you to send us your project so we can take a look and see what is wrong with the configuration.
