I can't seem to be able to get the ComboBox to (when type-as-you-go LoadOnDemand is enabled) to update my DataList control I have no my page. The Items_Requested event is getting fired, and all my code is being run through, but my DataList is not getting updated. I've input an AjaxManager and have made sure the ComboBox was set to be able to update the DataList. The Text_Changed event, however -- works.
