EnableLoadOnDemand in GridDropDownColumn

[Lukasz Kalbarczyk]

We have:     

...
<telerik:GridDropDownColumn DataField="ID_Firma" HeaderText="Firma"

            ListTextField="Nazwa" ListValueField="ID" UniqueName="ID_Firma" DataSourceID="FirmyDataSource" HeaderStyle-Width="480px"></telerik:GridDropDownColumn>
...

...

       protected void Page_Load(object sender, EventArgs e)
        {
            StanowiskaDlaFirmGrid.ItemCreated += new Telerik.Web.UI.GridItemEventHandler(StanowiskaDlaFirmGrid_ItemCreated);
        }




        void StanowiskaDlaFirmGrid_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)
        {
           if (e.Item.OwnerTableView == StanowiskaDlaFirmGrid.MasterTableView && e.Item.IsInEditMode)
            {
                RadComboBox combo = (RadComboBox)e.Item.FindControl("RCB_ID_Firma");

                combo.HighlightTemplatedItems = true;
                combo.AllowCustomText = true;
                combo.EnableLoadOnDemand = true;
                combo.Width = Unit.Pixel(400);

            }
        }

...

But after key was pressed (any) all items are visible, not the filtered only... Could you help me? Or should I use GridTemplateColumn?

combo.Filter = RadComboBoxFilter.Contains;
combo.IsCaseSensitive = false;
combo.Sort = RadComboBoxSort.Ascending;
combo.SortCaseSensitive = false;

I've added this and it works.
