Hello Kjell,
In Load on Demand scenarios, which yours seems to be since you are using the ItemsRequested event, the items are not available on the server, thus RadComboBox1.Items.Count will always return 0 in the Page_Load handler. You can review the following documentation article, which provides more details on the properties that can be used on the server when the ComboBox items are loaded on demand.
