The WinForms ComboBoxEdit uses incremental search to find items. This behavior is different from that of a standard combobox. This example demonstrates how to customize the DevExpress ComboBoxEdit control to behave like a standard combobox.
The example creates a custom ComboBoxEdit and overrides the FindItem method and AutoSearchText property. Note that the RepositoryItemButtonEdit.TextEditStyle property should be set to TextEditStyles.DisableTextEditor.
