TcxTreeListBand.OnGetStoredPropertyValue Event
Enables you to provide values for band properties to be saved to external data stores.
Declaration
property OnGetStoredPropertyValue: TcxGetStoredPropertyValueEvent read; write;
Remarks
This event is fired for each property (including default properties) within the list specified in the band’s OnGetStoredProperties event handler. To restore band properties, handle the OnSetStoredPropertyValue event.
The Sender parameter specifies the current band.
The AName parameter identifies the property name.
Pass the property value as the AValue parameter.
The following code represents an OnGetStoredPropertyValue event handler demonstrating how to save the values of a band’s Expandable property previously specified for storing within the band’s OnGetStoredProperties event handler.
procedure <Form>.<Band>GetStoredPropertyValue(Sender: TObject; const AName: String; var AValue: Variant);
begin
if Sender is TcxTreeListBand then
begin
if AName = 'Expandable' then
begin
AValue := TcxTreeListBand(Sender).Expandable;
Exit;
end;
end;
end;
