Ensures the internal TDBLookup instance is updated when the control is used in "unbound" mode.

Declaration

Source position: dbctrls.pp line 868

protected procedure TDBLookupComboBox.DoAutoCompleteSelect; override;

Description

DoAutoCompleteSelect is an overridden method in TDBLookComboBox which re-implements the virtual method from the ancestor class. It does not call the inherited method.

DoAutoCompleteSelect ensures that the dataset for the ListSource is re-positioned when the value in ItemIndex has been changed. This includes calling the UpdateData method for the internal TDBLookup instance when the control is used in "unbound" mode (without a DataSource or DataField).

DoAutoCompleteSelect is called when the KeyUp method handles an alphanumeric key entered while the auto-complete feature has been enabled in AutoCompleteText.
