RadComboBox supports a number of server-side events that let you respond to events with complex actions that can't be performed in client-side code.

• ItemsRequested occurs when the load-on-demand mechanism needs to add items to the combobox.

• ItemCreated occurs when a new item is added to the Items collection.

• ItemDataBound occurs for each item when it is being bound to a data value.

• SelectedIndexChanged occurs when the selected item has just changed.

• TextChanged occurs when the text in the input area has been changed.

Note
The SelectedIndexChanged and TextChanged events do not fire unless you set the AutoPostBack property to True.
