Hi, i'm usign a RadComboBox (RadControls_for_ASP.NET_AJAX_2010_1_519_dev) with EnableVitualScrolling and ShowMoreResultsBox as in your example
http://demos.telerik.com/aspnet-ajax/combobox/examples/populatingwithdata/autocompletesql/defaultcs.aspx
The loading on demand works, but the ShowMoreResultsBox is graphically different from your example (I have only the down arrow without the items numbers) and using the keyboard it don't loads the next page when the cursors reach the end of the current page, as in your example.
I must use the mouse clicking on the ShowMoreResultsBox arrow.
Attached as it appears to me.
Why this difference? I can't find any missing settings.
Thanks
Alessandro Strazzari
