InfoPath Dev

Hello All,
I want to refresh a secondary data source that is bound to a combobox in an infopath 2007 form. When the changing event is called, something happens and a new value is added to the database which is the source for the secondary data source attached to this combobox. Immediately after i want to refresh the SDD so that this new value appears in the list... I have seen on some other posts to do this you would use the following statement in infopath 2003... what is the equivalent in 2007???

XDocument.DataObjects["Secondary DataSource Name"].Query();

thanks!

Hello Everyone,
I actually found another way to refresh the datasource.. using this line of code will do it..

this.CurrentView.ForceUpdate();

thanks,
Erin

Sorry about that, i gave a wrong answer.. it's actually

this.DataConnections[dataconnection].Execute().....
