Be sure to clear the entry in the drop-down whenever you switch, otherwise you might get bad input.https://www.infopathdev.com:443/forums/thread/13098.aspxWed, 28 Mar 2007 20:28:32 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:13098dlgross0https://www.infopathdev.com:443/forums/thread/13098.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=45&PostID=13098I would like to be able to change the secondary data connection that is used by a dropdown when a user makes a choice in an option group. How can I do this in VB.Net?
