Remarks

The TcxLookupDBGridColumn object represents a column within the dropdown list of a lookup combo box. Columns provide a convenient data representation and allow the performing of different actions (sorting, for instance). All columns are stored within the LookupComboBox.Properties.ListColumns collection. Each column corresponds to a LookupComboBox.Properties.ListSource field. The names of all fields to display within the dropdown list are specified via the LookupComboBox.Properties.ListFieldNames property.

A user can create or remove dropdown columns either by using the LookupComboBox.Properties.ListColumns collection editor or by adding or removing names of the required LookupComboBox.Properties.ListSource fields to the LookupComboBox.Properties.ListFieldNames property value.
