TDBLookupListBox.ListSource property

Declaration

property ListSource: TDataSource read GetListSource write SetListSource;

Description

ListSource is a TDataSource property which contains the datasource component used to access the lookup dataset for the control.

Read and write access to the property value is redirected to the DataSource property in the internal TDBLookup instance used in the control. Assigning a new value to the property causes the UpdateLookup method to be called to re-initialize the TDBLookup instance and the value in the ItemIndex property.

Use ListField or ListFieldIndex to specify the field with the descriptive value displayed in the control. Use KeyField to specify the field with the value stored in the DataField for the control.
