Summary

Base class for Lookup support TJvLookupControl is the base class for controls that provide the user with a list of lookup items for filling in fields that require data from another dataset.

run\JvDBLookup.pas


Pascal

 run\JvDBLookup.pas
 TJvLookupControl = class(TJvCustomControl);


Description

Use TJvLookupControl as a base class when defining controls that permit the user to set a field value by selecting a corresponding value from another dataset. The TJvDBLookupCombo and TJvDBLookupList controls are both descended from the TJvLookupControl and provide the user with automatic lookup capabilities that are implemented in the TJvLookupControl object.
Do not create instances of TJvLookupControl. Instead, instantiate a descendant of TJvLookupControl to allow the user to set field values from a set of lookup values.
