My issue is very similar to the case described in: http://www.telerik.com/community/forums/aspnet-ajax/combobox/2010-1-415-radcombobox-automatic-load-on-demand-broken-after-any-postback.aspx
I have a RadComboBox with LoadOnDemand=true and have implemented the ItemsRequested method in my codebehind. I'm using AutoPostBack=true.
My problem is that after selecting an item (and the postback completes), I see this behaviour:
1) I clicked the arrow to open the combobox
2) The ItemsRequested event fires on the server
3) The combobox opens and shows only the selected item
4) I click elsewhere on the screen to blur the combobox
5) I open the combobox again
6) All the list items appear in the combobox but ItemsRequested wasn't called again.
I'm puzzled why this is happening. If I am trying to open the combobox (after a postback) and this triggers the ItemsRequested event, why do the items not appear in my browser until I re-open the combobox?
Is this a bug in RadComboBox, or is there some client JS I could use to get the items re-populating on a subsequent click? Is there a common use case for RadComboBox using both LoadOnDemand and AutoPostBack, or am I trying to use it in an unintended way?

Hi Stefan,
The same use case works fine in our live demos here. Which version of Telerik.Web.UI are you using? Is your setup different from the one in the demo?
Best wishes,
