TValueListEditor.OnGetPickList property
Event handler signalled to load values for the PickList in an item.
Declaration
property OnGetPickList: TGetPickListEvent read FOnGetPickList write FOnGetPickList;Description
OnGetPickList is a
TGetPickListEvent property with the
event handler signalled to load the PickList for the item with a specific key
name.
OnGetPickList allows the application to provide custom selectable values for
an item which uses the
esPickList editor style.
OnGetPickList is signalled from the GetDefaultEditor method when
an item definition in ItemProps uses esPickList in its
EditStyle property.
An application must implement and assign a routine to the event handler to respond to the notification. The arguments for the event handler include the control instance, the key name for the item, and a TStrings instance where the values for the pick list can be stored. Existing values in the pick list can be modified or replaced entirely.
